EXPERIMENTAL STUDY OF PERFORMANCE AND EMISSION CHARACTERISTICS OF A SINGLE CYLINDER DIESEL ENGINE USING KARANJA BIODIESEL AND DIESEL BLENDS

The primary source for propulsion in many vehicles is an internal combustion engine. The biggest challenge for engineers is to meet the current emission norm. Injection pressure, injection timing, combustion chamber geometry, climatic conditions, swirl rate are the factors which influence in direct injection diesel engine characteristics. The electronic fuel injection system is the advanced technology which uses high pressure fuel system and accurate timing of fuel injection controlled by electronics. In this work the study of properties of fuel and mechanical and electronic injection system are done. This experiment is done in 5HP, single cylinder direct injection diesel engine with a constant speed of 1500rpm. The mechanical spring loaded injector and electronic fuel injector is used to perform the test. In this work karanja oil methyl ester is blended with diesel based on volume fraction 20% of karanja with 80% of diesel. Performance and emissions are compared by using mechanical injection system. Adavnced electronic fuel injection system is replaced the mechanical injection system and the comparison is done.
