Professor, Department of Mechanical Engineering, S.S.P.A.C.E Wardha, Maharastra, India ABSTRACT The diesel engine is the most efficient power plant among all known types of internal combustion engines. Heavy trucks, urban buses, and industrial equipment are powered almost exclusively by diesel engines all over the world and diesel powered passenger cars are increasingly popular. Increase in petroleum prices, threat of global warming has generated an interest in developing alternative fuels for engine. Technologies now focusing on development of plant based fuels, plant oils, plant fats as an alternative fuel. In diesel-Cotton seed oil, Mahua oil blend, the specific fuel consumption of blends is more than that of diesel, this is due to lower calorific value of the fuel, and engine consumes more amount of the fuel in order to produce the same out-put power as in the case of pure diesel and the brake thermal efficiency of all the blends are lower than that of pure diesel [2]. This project Thermal Analysis of Four Stroke C.I Engine Using Biodiesel (Cotton Seed and Mahua oil with diesel blend under different load conditions. This project will give the perfect combination of diesel- Cotton seed oil, diesel- Mahua oil blend, so that problem of lower calorific value as well as more fuel consumption will be avoided. In rural area Mahua oil is mostly mixed with diesel, It causes some effects on environment as well as engine performance and life of the engine. As Mahua oil is easily available, it will be use with diesel and Mahua oil especially in rural areas. In this project the properties of the different blended fuel will be test in the laboratories. Several engine parameters like brake specific fuel consumption, brake power, brake thermal efficiency, etc. will be determine for all blended fuel.

INTRODUCTION Energy is one of the most significant inputs for growth of all sectors including agricultural, industrial service and transport sectors. Energy has been at the centre stage of national & global economic development from several decades. The demand for energy, around the world is increasing exponentially; specifically the demand for petroleum-based energy [2]. India with the high rate of economic growth and increase in the population is the significant consumer of energy resources. India lacks in sufficient energy reserves and dependent on oil imports, but India has an abundant re-source of vegetable oils. The use of vegetable oil in a diesel engine is not a new concept. In fact early engines were demonstrated with straight vegetable oils (SVO). Vegetable oils were proved to be very costlier during those days. However due to limited reserves of fossil fuels, escalation nature of diesel fuel prices and increase in environmental pollution, created a renewed interest of research in vegetable oil as substitute fuel for diesel engines. Vegetable oil is easily available, renewable and environment friendly. Vegetable oils have energy content suitable for use as a fuel in diesel engines. Some of these oils have already been evaluated as substitutes for diesel fuels. However, several operational and durability problems of using straight vegetable oils in diesel, caused by their relatively higher viscosity compared to mineral diesel. This viscosity can be brought into the acceptable range by transesterification, by blending of vegetable oil with diesel, or by preheating the vegetable oil.
