The depletion of oil resource and change in global warming has led to the development of alternate energy resources. Commercially the LPG gas is used as alternate fuel for the spark ignition engine. In this work an experimental investigation is done on Liquefied Petroleum Gas (LPG) along with dual fuel mode of diesel as an alternative fuel for four stroke compression ignition engines. The primary objective of this study was to analyze the performance and the exhaust emissions of the engine using different LPG flow rate. The engine used in the study was originally a single cylinder, four-stroke compression ignition engine and minor modifications were carried out to permit the experiments to run on LPG fuel. The LPG is supplied in the suction stroke mixed with air while diesel is injected at the end of the compression stroke to initiate the combustion process. The LPG is made to flow with different levels of 3%, 6%, 9%, 12%, 18% and 21% on the volume basis with Diesel 100%.
