Carnage in Kishtwar

Gun toting militants swooped on two remote hamlets of Kishtwar and gunned down 20 civilians, including 4 women in a display of crass barbarianism. The carnage, coming close on the heels of the massacre at Sheshnag, which claimed 13 lives including 6 Amarnath pilgrims, has caused widespread resentment all over Jammu and Kashmir. The authorities, fearing violence, have clamped curfew in tehsil headquaters of Kishtwar and Bhaderwah in Doda district. Security has been beefed up in Jammu, Udhampur, Kathua and other towns of the region apprehending communal clashes. The Shiv Sena has given a bandh call in Jammu and humblings of simmering anger can be heard in other towns around Jammu. The blood-thirsty hounds of Pakistan's Inter Services Intelligence, masquerading as "freedom fighter" have not really crowned themselves with glory by snuffing out lives of 20 unarmed men and women in cold blood. It was a shameful act of cowardice to mow down hapless civilians, who could not have put up any resistance against the heavily armed barbarians. However, there was a method in the militants' madness. Like last year, after the bloodshed at Pahalgam in which 35 Amarnath pilgrims lost their lives, the militants had struck at several remote, places the very next day to gun down over 65 innocent members of the minority community likewise the militants, on this occasion, have resorted to selective killings of members of the minority community. Their objective is to trigger off communal clashes. Hopefully, the people at large will refuse to play in the hands of the enemy. The need of the hour is to maintain peace and communal harmony and frustrate the designs of the ISI to plunge the State in chaos and anarchy. Public resentment and anger against the Government for its perceived failure in protecting the lives and links of people residing in remote, inaccessible hilly regions is understandable. All the same, there need to understand the limitations of the authorities in providing security to each and every hamlet in remote interior. Militancy in Jammu and Kashmir has been raging for about 12 years now. There is no likelihood of its crumbling in the forseeable future. Therefore, we have to learn with it. At the same time we have to draw up long-term plans to deal with menace. The task of providing security to isolated hamlets can perhaps be achieved with regrouping of villages at vantage points and linking the regrouped villages with motorable roads. The experiments in Mizoram had paid rich dividends. The men in-charge of security could possibly examine the feasibility of regrouping the villages into adequately guarded smaller towns. Meanwhile, there is urgent need to step up the operations against the terrorists all over the State. They have mistaken Prime Minister's various peace initiatives as a sign of weakness and mounted series of attacks on soft target like pilgrims and unarmed civilians. The current situation calls for giving the army to crush the militant movement with ruthlessness. Terrorism and terrorists cannot be eliminated by pursuing a kid-glove policy. There is urgent need to launch all-out operations against the so-called jehadis. The Kashmir tangle is undoubtedly a political problem. But terrorism is basically a military problem. While there is no denying that the Kashmir imbroglio would ultimately have to be resolved through a political dialogue, we can ill-afford to let the terrorists get away with murder and mayhem. And as the pressure is mounted on the terrorists, the lackeys of Pakistan in the separatist Hurriyat Conference are likely to intensify their disinformation campaign to malign the security forces. However, this should not deter the security forces to deal mortal blows to the mechants of death.

AJIT'S INDUCTION INTO CABINET

With an eye on the Assembly elections in Uttar Pradesh, Jat leaders Ajit Singh was into the Union Cabinet on Monday ahead of formalising an alliance between the BJP and his party Rashtriya Lok Dal. Singh, son of erstwhile Prime Minister Choudhary Charan Singh, was elected from Baghpat in Uttar Pradesh. He makes a comback into the Cabinet for the third time. His earlier stints were as Industry Minister in the V. P Singh Government and as Food Minister in the Narasimha Rao Ministry. Of late, he has been compaigning for a separate 'Harit Pradesh' to be carved out of Western UP's jat belt. Ajit's co-option into the NDA comes amidst reservations expressed by another Jat leader and Haryana Chief Minister Om Prakash Chautala. With his entry, the strength of the Union Council of Ministers has gone upto 78. RLD has two members in the Lok Sabha. With his induction in the Union Cabinet, Ajit's flip-flop has finally come to a halt. It has also ended speculation about the poll pact talks with various groups including Rashtriya Kranti Party of Kalyan Singh, Congress or the Bahujan Samaj Party, Ajit's RKD has substantial following in the jat-belt in Western Uttar Pradesh and the RKD - BJP combination will be a potent force in the area. The BJP, facing the prospects of a rout in view of the anti-incumbency factor and intense infighting party, is expected to draw some solace from the tie-up with RKD. But this may not be enough to shore the fortunes of the BJP. The saffron party is working on various permutations and combinations in UP. It can ill-afford to lose power in Uttar Pradesh. Therefore, it will go to any length to retain its hold in UP. Prime Minister's invitation to the Agra summit and his subsequent hard-line approach on Kashmir is believed to have been prompted by the compulsions of electoral politics in Uttar Pradesh. If that be so, it would be naive to expect any meaningful dialogue on Kashmir with Pakistan till after the polls in UP. Meanwhile, the BJP, piggy - riding the Rashtriya Lok Dal, will be busy cultivating greener pastures in Western UP and Ajit Singh could pursue his sole agenda of the creation of Harit Pradesh while staying in the National Democratic Alliance Government. The minor Cabinet reshuffle had a good news for the denizens of Jammu and Kashmir. Omar Abdullah, who made a favourable impression with his deft handling of the Commerce and Industries portfolio, has been shifted to the glamorous External Affairs Ministry. Omar, who is being groomed by his father, Dr Farooq Abdullah, as his successor, will now have the opportunity of studying first-hand the hurly burly of international politics and widen his perspective on international relations. The idea behind shifting Omar Abdullah from Commere to External Affairs was to field the articulate junior Abdulalh in explaining India's position on Kashmir, particularly to the Islamic world, to counter Pakistani propaganda. The installation of Ajit Singh as a Minister in the NDA Government sets the stage for a BJP-RJD tie-up in UP which could have a bearing on 90 seats in the western part of the State.

What ails the education in India

By Preduman K. Joseph Dhar

In India education has always re-mained the first casualty. It is not without reason. The politicians never want the common man to get sufficiently educated for fear of posing a challenge and threat to their very existence. The Bureaucrat also never wants it. He shall find his counterpart from the commonfolk than his own household. In his budget speech for the fiscal year 2000-2001 owe Finance Minister accorded highest priority to human resources development through programmes, and policies in Education, health and other social services, with special emphasis on the poorest and weakest sections of the society. The outcome as observed by us in India of this speech is before us all.

Every student of economics can easily understand that India enters the second phase of liberalisation, the Government is expected to reduce its fiscal deficit by cutting down public expenditure and confining its activities to the minimum. Under the market economy which economic liberation aims at, the Government is expected to concentrate only on Defence, Law and order and Justice. But we in India, should at the same time take due note of the fact that eduction is one of the importnat factors that decide the fact education is one of the important factors that decide the fate and quality of life of a society, Literacy is one of the important elements included in working of Human Resource Development Index (HDI) that ranks countries in order of development. India's rank of 132 in 1999 leaves us with a high illeteracy rate of 38 percent combined with low per capita income (US $370 or US $1900 adjusted for purchasing power party). If we care to read the book Indian Economic Development and social opportunity by Dreze and Amartya Sen, we will know for ourselves very clearly the importance of education in economic and social transformation in a developing country like ours.

The Government, therefore, cannot hoodwink the innocent people of India by taking recourse to be proposed 83rd Amendment to our constitution which aims at a making primary education in the age group of 6-14 compulsory. We have a provision of the type in part IV of our Constitution - Article.

In 1986 the Congress Government headed by the late Mr. Rajiv Ratna Gandhi emphatically said on various occasions that his Government would spend 6 percent of Gross Domestic Product (GDP) on education. But statistics of 1996 reveal that the Government of India has spent 3.4 percent of GDP on education. As against this a country like Kenya has spent 6.6 percent of its GDP on Education if the world development Report 1999-2000 could be any guide. Our expenditure on education has increased from 0.65 percent of GDP in 1951-52 to 3.40 percent GDP in 1996-97. If we compare the increase in the budgetary expenditure during the same period, it has gone up from 7.92 percent to 13.35 percent. This increase has not succeeded in making the country fully literate. The India Development Report prepared by the Indira Gandhi Institute of Development Research suggests providing of 2.85 percent of GDP against 1.5 percent of GDP actually being expended to provide Universal Parimary Education.

The National Council of Applied Economic Research says "Sixty Eight percent of the students go to Government Aided schools and the remaining ten percent to private schools where the expenditure is 230 percent more than the Government Schools. Under the Directive Principles of State Policy, the Government is obliged to provide 8 years of free and compulsory education. Here it shall be apt to suggest that the proposed 83rd. Amendment to the Constitution should extend this education to 10 years that is 19th standard, the first public examination. It shall definitely require Government to spend all the 6 percent of the GDP and even more. If the Government is sincerely wishing to provide qualitative education suitable for the requirement of the present day economy and society, then it should not be found wanting.

Now the question arises -- If we base our approach on the principles as enumerated herein above what about +2 Education and above? Who spends for higher education? Educationists and economists opine that those who have the benefit of higher education will be economically and socially better off than those who could not avail of such opportunities.

World Bank Report 1998-99 says, "Laburve Markets rewards those who possess college degrees and other tangible signals of ability. It is, therefore, the bounden duty of the Government to bear the burden of such education. Qualitative education means excellent infrastructure and competent teachers who cannot be had by paying peanuts.

It is a stark truth that higher education does not cover the priority sector vis-a-vis expenditure on it. But here it can be suggested that Government should say good bye to populist policy of spending for it. But at the same time let the Government advance education loans to economically poor students who derive to acquire higher education. Such schemes were already introduced in Australia in 1989 and Newzealand in 1992. The repayment of loan begins when the student starts earning.

In a liberalised economy, the market will decide the worth of higher education. The economic Survey Report says "The early success of our IT industry owes a great deal to relative absence of Government controls". In this context it shall be proper for the Government to exercise minimum control and greater freedom in the field of higher education.

India has rolled out a red carpet to global economy. She is also a player in this field. But to be a player does not fulfill the requirements. We have to be a successful player. What we need for this purpose is revamping of our education system from the primary stage onwards. This not only needs huge expenditure on school education but also proper direction. Let the Government take care of school education and leave higher education, by and large to the market.

Here it shall be pertinent to State tha school education should not be made like a ruderless vessel to be drifted any time ashore. It should be left to the care Educationists and not to IAS Officers who have no knowledge in the field as is the case in Jammu and Kashmir. In our State we find Principal's of Higher Secondary Schools, lecturers of Higher Secondary Schools without the B.Ed. degree. In our State Institute of Education the syllabi planners and those who train teachers in various disciples without B.Ed. degree. Our Chief Education Officers constitute such a lot who have never managed and taught primary, middle and secondary schools. Our J & K Board of School Education has always been administered by college teachers with no basic knowledge of the psyche of those whose affairs they conduct.

If India is to progress education should not be the casualty.

Post-summit Pakistan offensive in Kashmir

By Avinash Shirodkar

Indians like to say Pakistan's econ-omy cannot sustain what some New Delhi officials call its "compulsive hostility" to India. Actually, that's untrue. The proxy war is cheap and self-sustaining. The real burden is the negative impact the war has on third countries, including ones crucial to Pakistan's economic revival. And as the Agra summit made evident, Musharraf hasn't realised this yet.

The general has a long and distinguished record of beating on India. That's par for the course. He's a good soldier, an ardent nationalist. Musharraf isn't anti-Indian because of religion or Partition. For him, it's about geopolitics. He told officers in 1999 that even if the Kashmir dispute is resolved, "our problems with India may not end, because India wants to keep Pakistan weak. Pakistan is a thorn in India's side, constantly thwarting India's ambition to become a world power".

With the above mind set, it would he a worthwhile exercise to examine the collapse of the Agra summit. Whether to call it a roller-coaster ride, or a Cheshire cat which, having started off with a big grin, vanishes without trace. But there could have been absolutely no question about the tragic fate that has overtaken it. Observers who had scaled euphoric heights following the initial description of the talks as 'fruitful', 'constructive' and 'positive' have come down to earth, with nothing more than a few photo-ops to show for it.

Last-minute efforts by participants furiously searching for some semantic fig leaves or diplomatic camouflage to justify their having met at all, and roused expectations of some momentous breakthrough have also collapsed. Thus, there is not even a bland declaration or a joint statement whose significance would, in any case, have been not in what it said but in what it papered over - that for the umpteenth time the two sides have met only to part after having engaged themselves in a dialogue of the deaf.

The denouement should not have come altogether as a surprise. During the run up to the summit itself, it was clear from the pronouncements by various sources and at various levels - political and official - emanating from India and Pakistan that neither country was going to yield an inch of ground on what each regarded as its paramount concern : Cross-border terrorism on India's side and Kashmir on Pakistan's. Neither the Prime Minister, Mr Atal Bihari Vajpayee, nor the Pakistani President, Gen. Pervez Musharraf, could have survived a day in their respective capacities if they were seen to backtrack on asseverations that they themselves had helped burn into the psyche of the people of their respective countries as inviolate, sacred and sacrosanct.

It is necessary to take with a pinch of salt the familiar refrain that the pitch was queered for the summiteers by the hardliners - the obdurate Shiv Sainiks and Sangh Parivaris on the side of India and the fanatical Lashkarites, Jamaatis and Hurriyatis on the side of Pakistan. To persist in this belief will be an act of self-delusion. In both countries, there is a sizeable section of opinion in every walk of which is convinced of the rightness of the stance taken by their own countries so far and would have considered any abrupt climb down as a suspicious sell-out. Included within its ambit are the academia, media, intelligentsia, professionals, litterateurs, apart from the political class and the military, all of them trying to be objective and dispassionate after their own fashion.

Apart from the intrinsic complexities of the issues bedeviling relations between India and Pakistan for more than half a century, there were genuine misgivings on the Indian side on the durability, or even legality, of any entente cordiale entered into with one who had anointed himself President after seizing power from a democratically-elected Prime Minister and summarily dismissing a President who had been duly installed by a legitimate process.

Also, there could well have been honest doubts about the trustworthiness of a person with whom the Prime Minister, Mr Vajpayee, had forsworn any dealings at all knowing that the blood of 500 men of India's Defence forces was on his hands in the flare-up at Kargil planned and instigated while the ink on the Lahore Declaration was not even dry.

In a sense, therefore, the talks were foredoomed to failure. What India had not foreseen was that their failure would give a ready and heavy propaganda advantage for Pakistan. It has already thrown the blame on India for the breakdown. It will now surely present itself before world opinion as the injured party and India as a country unreasonably brushing aside the existence of a dispute over Kashmir and bent on crushing a "freedom struggle" by Kashmiris with the armed might of six lakh soldiers of the Indian Army.

Gen. Musharraf has very cleverly scored points in advance by setting out all these arguments for Pakistan's brief for world forums when he met the editors on July 16 over breakfast. Since governments of other countries will have nothing to go by except the plausible sob-sister stuff put out by Pakistan, by the time India catches up with the disinformation campaign, much mischief would have been done. Instead of focussing time and energy on his other worries such as the economy. Manipur, Tamil Nadu, and the like, Mr Vajpayee will be sorely distracted devising strategies to combat the mischief on all the fronts.

This is not all. Pakistan will make the breakdown an excuse to throw all its weight behind the militants in Kashmir in order to intensify acts of subversion and violence, and create an illusion for the outside world of widespread escalation of resistance to Indian 'occupation' of Kashmir. India's use of the armed forces to control the situation will be depicted as a heartless oppression of a "freedom movement" in violation of canons of international law. In the process, India may even be hauled up before the Security Council or the International Court of Justice for trampling on human rights and the principle of self-determination. Nothing can be taken as far-fetched when other nations are either ignorant or biased or are eager to fish in troubled waters.

Where does India go from here? Pinning hopes on the visit of Mr Vajpayee to Islamabad, or his meeting Gen. Musharraf at the time of UN or SAARC meeting is to exhibit naivete of the first order. So long as the concerns which each side regards as core and non-negotiable remain the same, more parleys will not mean getting closer to agreement.

The time has come to make clear that the problems pertaining to Kashmir are to be sorted out between India and the people of one of its constituent States, and it was a mistake to concede any status or stake to Pakistan in what principally is a matter of upholding India's integrity and sovereignty. It was this approach that has helped India meet with a degree of success in countering separatist movements in Nagaland and Mizoram which at one time loomed large and ominous.

It would be a wise policy for India to tell Pakistan where it gets off, and concentrate on winning over the people of Kashmir by talking to them within the spirit of the Constitution and by giving topmost priority to economic development and creation of employment opportunities.

It will have to put in a lot of patience, imagination, empathy and sensitivity in effecting a turnaround in the situation. Kashmir does not lend itself to the conventional methods of deputations and postings of functionaries subjected to shuffling and shunting after short durations. It is time a special corps of committed, sympathetic and innovative public servants who have the reputation of achievers in various fields, professions and disciplines was constituted exclusively for Kashmir and given the support and authority to solve the problems encountered by them in the best interests of the State and the nation.

After Agra Summit

By Mohan Singh

India had already held dialogues at Simla Summit, at Lahore Summit and at othe places at the highest level. The Agra Summit was one of such Summits to hold dialogues to discuss the issues and solutions thereof being faced by the two countries. We should continue to hold dialogue with Pakistan in the interest of both the countries and for peace in South East Asia. But it should not be at the cost of Democracy and Secularism, the two cherished principles of India. Jammu and Kashmir is part of India, as it has not be at the cost of Democracy and Secularism, the two cherished principles of India. Jammu and Kashmir is part of India, as it has not been corved out of Pakistan.

I would not hesitate to express that at Agra Summit India lost the bout in diplomatic area. General Mushharaf was forthright and put forth his case on Kashmir in such a way that it gave an imprssion that India's position on Kashmir is weak and that Pakistan has the right to ask for its settlement on the basis of two-nation theory. General Mushharaf has had his way in putting his views by talking to Hurriyat leaders, by not giving recognition to official level talk and not considering Shimla Agreement and Lahore and Pakistan support to militant organisations on the ground that it is a freedom struggle for liberation of Kashmir, though Kashmir is legarlly and constitutionally a part of India and not its colony. He even gave an impression that Pakistan was morally correct to invade Kargil to avenge for providing help by India to Bangladesh for its separation and occupation of Siachinly India.

We invited him when he was Chief of Pakistan Army Staff and Chief Executive Officer; at that time he was not the President of Pakistan. India wanted to find a solution to the vital problems being faced by the two countries and reach a mutual settlement over Kashmir in the interest of people and peace in South Kashmir in the interest of people and peace in South Asia inspite of the fact that he was the Chief Architect in invading Kargils. It was with that view that he was accorded suprecented welcome and was given the widest possible publicity by media. By coming to India Gen. Mushharaf in a way legitimised his position and wanted to stablize himself by clinching a deal over Kashmir.

Right from 1972 onwards we have been following a policy of appeasement with Pakistan which has not paid dividends. At Agra Summit Gen. Mushharaf did not reconcile to his stand on cross-border terrorism and Kashmir issue, to which he termed as dispute. In fact India is the 2nd largest Muslim populated Country, which includes Muslims of Jammu and Kashmir. In 1947 Muslim majority State of Jammu and Kashmir acceded to India led by Sheikh Mohd. Abdullah ignoring two-nation theory. If Muslim majority is the consideration for Pakistan and claim Afghanisthan as well as it used to be part of India earlier. Religion is no criteria or consideration for creating or alterin States. India is a multi-religious, multi-racial and multi-lingual country. It has, as such, to remain a secular State and work to strengthen it.

Any compromise on Kashmir would weaken the secular fabric of this country, Kashmir is a symbol of unity and integrity of India. It is in the larger interest of both India and Pakistan that status quo of Kashmir should be maintained.

We should continue to talk to alleviate poverty, illiteracy and unemployment and work for development and welfare of the people of Jammu and Kashmir. Both the countries should take measures to restore peace in the strife-torn State. It should be made centre of Trade by opening trade routes with Central Asian countries, China and other countries. Kashmir should again become a centre of learning. There is need for revial of handicrafts industry and tourism and harnessing of natural resources for the development and the welfare of people. Both the countries should make endeaour to settle the people instead of unsettling them.

Unrest in the Kashmir Valley needs to be looked into and its causes to be dealt with for restoration of confidence of the people. The promises given to them should be fulfilled and consitutional gurantees given to them should be maintained to win over the people of Kashmir. They may be mentally prepared for peace. At the same time all out efforts should be made to preserve Kashmiriat so that the identity of the Kashmiries remain intact. We should continue talking on nuclear control, peace and trade issue. To reach this destination and solve the issues including that of Kashmir let us construct the road firsgt by holding dialogues in future.

Alcohol in diesel engines

By B. S. Murthy

In spite of the proven merits of etha-nol as an environmentally safe and high-performance renewable motor fuel for nearly three quarters of a century, it is unfortunate that India has not shown the political will towards wide application of alcohol fuels for motor vehicles. It is only after the recent article by Mr Ram Naik, Union Minister for Petroleum and Natural Gas that new hope has emerged for a revival of interest in this renewable energy source that could gradually replace patrol, thus greatly benefiting the economy.

In the mid-1930's, petrol/alcohol blends were used in the city bus service of Bangalore as an experimental measure, owing to the vision of the then Dewan of Mysore, Sir Mirza Ismail. And in Brazil, there was a strong political will to implement alcohol fuels as a national policy and be free from the burden of importing petroleum fuels. Mr Ram Naik's timely article has indicated that India too can gradually implement alcohol fuel technology for automobiles - first, as a blend in petrol cars, and subsequently as a sole fuel for both petrol and diesel vehicles.

Alcohol, especially ethanol or ethyl alcohol, has been recognised as a quality motor fuel, as the design of the first automobile (the original Ford Model-T) for the spark-ignition engine because of its high anti-knock value designated by the 'octane Number' and better performance in terms of power and efficiency. It is only recently (since the 1970s) that interest was shown in the use of ethanol and methanol as diesel fuels.

Alcohols are very difficult to burn by compression - ignition, because of their low ignition quality, usually designated by a low 'cetane number'. A high-octane fuel (a virtue for a petrol engine), necessarily has a low cetane value (a cure for the diesel engine). The main research in diesel-alcohol technology was to find ways and means to force alcohol to ignite by compression in the diesel engine.

It is interesting that India was the earliest to recognise the merits of burning ethanol in diesel engines. The bi-fuel system developed by the Prof H. A. Havemann and his colleagues at the Indian Institute of Science (IISc) Bangalore, in the early 1950s, was the subject of the earliest original published work in technical literature regarding alcohol diesels.

Essentially, this method involves giving carburettor benefits to a diesel engine. Part of the fuel-energy is supplied by inducting ethanol through a carburettor, while only a small quantity of diesel fuel is injected in the conventional injection system. Since alcohol and diesel oil (unlike petrol, which can be blended) do not mix, these fuels are sent through two different routes - by induction and injection.

Injected fuel, which is a smaller quantity, only serves as an ignition source, like millions of distributed spark plugs. By a proper choice of injected fuel, either diesel oil or vegetable oil, a large portion of ethanol --40-90 per cent - can be utilised by this method. This pioneering technique did not attract widespread application as the availability of petroleum fuels eased up, and there were no environmental constraints on the use of diesel oil in those days.

Similar approaches were concurrently investigated in the US and UK, but they did not use alcohol. Prof Paul Schweitzer of Penn State University "fumigated" the induction system of a diesel engine with different volatile fuels, while injecting conventional diesel oil to improve the air utilisation of the diesel engine and boost power.

In an impressive SAE publication on "Hybrid Engines", Professor Schweitzer referred to the research efforts at Bangalore on the novel attempts to burn a low-cetane fuel like alcohol by "fumigating" it to the induction manifold. Pennsylvania Sate Railway also showed interest in applying this technique for using alcohol in diesel locomotives.

The UK experience, in King's College, was aimed at improving combustion characteristics of a diesel engine by introducing small quantities of 'Secondary fuels' in the induction manifold and promote smooth pressure rise and low smoke emission. Though different names were adopted, the Indian, US and UK efforts were all directed at improving diesel combustion and promoting the use of alternative fuels. But only the Indian researchers directed their work towards ethanol for the partial substitution of diesel using this bi-fuel approach.

This alcohol-diesel powered vehicle (Standard 20 microbus) was demonstrated at the exhibition held by at Pragati Maidan, New Delhi. The results are briefly summarised below. (Details are documented in the Special Publication SP-480 of SAE on alternative fuels).

The heart of the technique was a special air-alcohol inductor, designed after extensive tests on a laboratory dynamometer. The novelty of this gadget is that under starting and idling conditions, the throttle of the single jet carburettor is closed an there is no flow of alcohol and the vehicle works on neat diesel oil. The throttle in the air arm is fully open when the throttle in the carburettor arm is fully closed. They are complementarily ganged. Together, they are linked by a flexible coaxial cable to the control lever of the diesel injection system which, in turn, is linked to the accelerator pedal.

The relative sizes of the venturi and the carburettor jet, and its position relative to the venturi, are designed such that the jet does not allow any alcohol till the predetermined speed compatible to efficiency and smoke number (as determined by the static dynamometer tests) is reached. At speeds higher than this, there is automatic controlled flow of predetermined alcohol flow conducive to the fuel efficiency and low smoke number. This technique permits complete working on diesel fuel in case of disruption in the supply of alcohol.

Road trials with the retrofitted diesel vehicle indicated that unto 45 per cent of diesel oil substitution was possible under transient conditions of driving on our roads. Bi-fuel systems can be introduced without major changes in the vehicle hardware excepting that two tanks are needed. Material compatibility with alcohol fuels has already been solved, just as in the case of petrol engines.

This system, while admirably suited to stationary engines, works on maximum alcohol substitution on diesel locomotives, which run at high speeds and constant load for long distances. Rectified spirit instead of anhydrous alcohol can be used. Fueling for fleet vehicles can be done without major changes in fuel supply and distribution infrastructure.

IIT Madras is credited with research on the use of alcohol as a sole fuel. Ignition of alcohol on catalytically activated surfaces in the combustion chamber has enabled its used as a sole fuel. Many results of collaborative work of IIT Madras and Santa Clara University as well as the Technical University at Aachen, Germany have become an important source of reference for research.

India can well start diesel-alcohol programmes on fleet buses, locomotives and stationary engines using the skills and potentials of the IITs, IIP and the universities. Expertise developed in India is already being used in other parts of the world ! INAV
