This Study, Analysis and Development of a Biogas Run Generator of 50 KW capacity at Pachane Taluka Mawal, District Pune is done for the production of electricity from the Diesel Engine which is run on biogas. The engine has to be modified with the use of 4 spark plugs for the combustion chamber so that biogas can be used as the substitute fuel. The other modification required to be done is to reduce the compression ratio of 16:1 for the diesel engine to 8:1 for the biogas run engine. This reduction of the compression ratio is achieved by grooving the piston to increase the volume of the combustion chamber and reduce the compression ratio of the engine. We also need to filter the gas as the raw gas contains CO2 which is a non-combustive gas and NOx and Sulphur which causes a lot of corrosion in the combustion chamber and thus causes problems of knocking etc. Thus we have a filter installed in between and also we have a gas pump that pumps the gas after the filtration process is over and thus achieves continuous flow of the gas. This avoids the knocking effect on the engine. We have also studied that the major gas generated is methane which is around 67-70 % and the rest are other gasses like CO2, NOx, and SO2 etc. 1.72 KWH is the output recorded for the generator output for the biogas having 63% of methane.
