Alternative fuels for IC engine

Alternative fuels for IC engine

Abstract

Edible & Non-edible vegetable oils have been projected as promising liquid bio-fuels as alternative diesel either for partial or full substitute towards power & transport requirements. There penetration to these sectors is confronted with two challenges, namely the need for alteration in the existing engines if they have to be used as exclusive fuel in them or to process the raw oils suitably to generate bio-diesel so as to directly use them in the present generation of engines However, these edible & non-edible vegetable oils in there verging state of availability are good candidates as full substitute for generating thermal energy in the existing devices like stoves, ovens, furnaces with a possibility of replacing diesel in diesel fired boilers & even in diesel base power plants, C.I. engines. To substantiate this & to gain experience to make us ready for such a well come transition, a few controlled experiments were carried out on Jatropha oil, Honge oil, & Rice bran oil as governing fuels. To standardize the methodologies, experiments were also repeated with blended fuels. Since the oil production in fact is rural based with the proper agricultural practices for growing the oil generating plant, the benefit of such a transition would go immediately to the rural community who can rely on the supply of this fuel for their every day energy needs. The environmental benefits of such an intervention also have been examined in our present study. In this paper we share this inventions with the hope that similar efforts from different quarters in order to fulfill most of our thermal energy needs devoid of fossil fuels in the near future.

Introduction

Oil is the engine of today’s economic growth. The erratic supply & threaten on availability force the oil price pass the $45 mark per barrel. Economists predicted that oil price will increase above $50 per barrel. The ever increasing price of oil & its limited source force many countries to look for alternative sources of liquid fuels to run the vehicles, power plants & industries. Already a few countries like Brazil, US, France have made headway in using ethanol as an alternate liquid fuel in place of petroleum products. Now, with a renewed effort on finding alternate fuel, edible & non-edible plant oils which once occupied a predominant place as an energy source breathes a new lease of life. Today every measure country has its own energy program based on vegetable oils/ plants oils. Preliminary studies proved that plants oils can be good replacements of petroleum oils. Many experiments are being carried out on the suitability of diesel engine to run with these oils. The quantity of diesel & furnace oil being used in industries for thermal applications & the requirement of kerosene in domestic usage these oil are considered a good candidate as a replacement fuel. Very few experiments are being done on this line today. So here in our center an attempt is made to find the suitability of plant oils for replacement of kerosene in domestic cooking stoves & diesel/furnace oil in oil burners & C.I. engines with these oils (i.e. Jatropha oil, Honge oil, Rice Bran oil) as a governing fuel. The initial outcomes of these experiments are encouraging to carry out detail analysis. In this paper we have made a brief summary of the scope of these oils in thermal applications.
