Investigation on LPG-Biogas Blends in Spark Ignition Engine

Abstract

Internal combustion engines normally operate with the nonrenewable sources such as petrol and diesel, which are diminishing at a faster rate. To avoid these problem alternative sources of energy must be opted for the operation of internal combustion engines. In this work biogas is selected as an alternative source of energy for the working of internal combustion engines but possess some limitations due to its high auto ignition temperature and high CO2 content in it. To overcome the limitations biogas is blended with LPG at different proportions of 5%, 10%, 15% are done. The modification of the internal combustion engine is performed to convert it into a gas engine and the tests are conducted on the modified engine with different proportions of blending at various loads. Based on the results of the test conducted the performance characteristics are analyzed.
