EXPERIMENTAL INVESTIGATION OF COMPARATIVE PERFORMANCE OF 4 - STROKE 4 - CYLINDER C.I. ENGINE OPERATING ON METHANOL , PETROL

Extensive research is under execution for attention diesel fuel through out the world as well as in india. The major research for this need are of two type , first is related to environment i.e. global warming due to conventional hydro carbon diesel fuel and second is economical i.e. increase the demand ,which causes increases in per barrel rate of this non - renewable source. The main objective of this work is to obtain a feasible solution to reduce fuel consumption .As we know in any country the main energy source for vehicle are petroleum product (i.e. petrol and diesel). The work is carried out on vegetable oil (non - edible). Karanja oil use for blending with petrol and mthanol in diesel. The purpose of using petrol and mthanol is to reduce viscosity of karanja oil. The testing of this blend fuel is carried out on a four stroke, four cylinder diesel engine . This work presents the experimental investigation performance characteristics of a diesel engine fueled with karanja oil (KO) and its 3.0 vol%, 5 vol%, 7.0 vol% and 10vol% blends with methanol (MKO), petrol (PKO) and both improving agents applied in equal proportions as 50:50 vol% (MPKO). The purpose of this work is to examine the effects of KO inclusion in Diesel fuel on the brake specific fuel consumption (bsfc) of a Diesel engine, its brake thermal efficiency, brake mean effective pressure, mechanical efficiency and volumetric efficiency, the tests were performed in a 4 - strokes, 4 - cylinder, and naturally aspirated, air - cooled and direct injection stationary diesel engine, diameter of cylinde r is 78mm and stroke length is 92mm at the different engine speed under full - load conditions. The results obtained with karanja oil blends were compared with the diesel fuel as reference fuel. The engine torque and power obtained with Karanja oil blends we re less, and the specific fuel consumption was found to be higher, which could be attributed to lower calorific value of blends, this work says that the performance of the engine for the blends of BPMKD10 is nearly pure diesel but fuel consumption increa ses in little amount. But we reduce about 20% consumption of petroleum product, which is using only 70% diesel and 30% mixture of one liter fuel, We also save non - renewable source i.e. diesel . The production of biodiesel from these oil provides numerou s local, regional and national economic benefits. To develop biodiesel into an economically important option in India biotechnological innovations to increase the seed yield are essential.
