Use of biomass as an alternative fuel in S.I. Engine - emission and comparative studies with conventional fuels

摘要

The background behind this work is the millions of Biomass gas plants across the rural India and the potential to enable power generation simple retrofit to a conventionally available maruthi engine so as to enable 100% biogas power on is attempted. Employments on one such 3 cylinder four stroke S.I. engine have been carried out with modification to supply gas. The performance of spark ignition engine using flue gas generated in a fixed bed down draft suction type gasifier using agricultural and forestry residues was measured on a eddy current dynamometer test bench. The parameter measured includes torque, power output emission measurement, exhaust gas temperature and combustion analysis for the operation on gasoline LPG and producer gas. Reductionof CO and hydrocarbons emission where attained. And the engine suffered less thermal stress under producer gas operation when compared to other fuels. While analyzing the combustion study it was found that heat release as well as the cylinder heat release the cylinder pressure are less for producer gas when compared to other two fuels.
