Experimental Investigation on Multi-cylinder Engine Using Petrol and LPG as a Fuel

Today's changing social and industrial scenario demands extensive use of fuel in vehicles which may lead to its depletion in near future. In view of the possible depletion of fossil fuel reserves, research is being done on various alternative fuels including renewable and non-renewable resources. In the present study, experiments have been conducted on a conventional multi-cylinder engine, which was modified to work on a duel fuel mode with LPG and petrol as fuels. Engine testing was carried out at variable speed and load using both the fuels. For the measurement of friction power loss Morse test was carried out. In order to measure the unaccountable losses heat balance sheets were prepared.
