Experimental Investigation on CI Engine using Diesel-CNSL-Ethanol as a Renewable Alternate Fuel

Abstract

Increased demand of fossil fueled to development alternative fuels like bio fuels and vegetables oils as fuel. All most all the CI-Compression Ignition engines use diesel as a fuel, but the diesel is one of the largest contributors to environmental pollution problems. Application of biodiesel as a substitute for conventional petroleum fuel in diesel engine gain ever increasing demand throughout the world wide, because it is produced from renewable resources, bio degradable and potential to exhaust emission more ever, use of biodiesel generates rural employment opportunities by cultivating such oil producing crops. Energy from biomass and more specific bio-diesel is one of the opportunities that could cover the future demand of fossil fuel shortage. Biomass in the form of cashew nut shell liquid (CNSL) represents a new energy source and abundant source of energy in India. In this, investigation on performance of four stroke single cylinder CI-Compression Ignition s engine with variable loads were studied, charged with 25%CNSLBiofuel and 75% Diesel blend (B25) with ethanol by volume tricot 5, 10, 15, 20, and 25% are used; compared with both Diesel and B25. The brake specific fuel consumption, brake thermal efficiency, Smoke of B25E10 is closer to that of Diesel and B25.
