Comparative Assessment on Performance of Multi cylinder Engine Using CNG, LPG and Petrol as a Fuel 2005-01-1056

In present study experiments have been conducted on a conventional multi-cylinder (MARUTI make) engine, which was modified to work on a dual fuel mode with CNG, LPG and petrol as fuels. Results of comparative tests involving spark ignition engines over a wide range of operating conditions are presented and discussed. Some of the performance characteristics considered are those relating to power output, friction power, indicated thermal efficiency, brake thermal efficiency, volumetric efficiency, fuel consumption, specific fuel consumption heat balance etc were studied at constant speed and variable load conditions. Finally, the relative operational aspects of two fuels are evaluated. It is then suggested that in this regard, LPG has some excellent physical, chemical and combustion characteristics that make it as a preferable fuel.
