Abstract—Present work shows a comparison of performance by using petrol and LPG at no load and different load condition. Work was done in I.C. engine lab of mechanical engineering department UIT RGPV Bhopal and found that fuel consumption was minimum at 2250 RPM in case of both fuels at no load and fuel consumption is minimum at 50% of the load in case of both fuels at loading condition. The experiment also shows that LPG gives maximum Brake Thermal Efficiency (BTE) at 50% of load and 31.32% less Fuel Consumption (FC) than petrol at load, low Brake Specific Fuel Consumption (BSFC), low Brake Specific Energy Consumption (BSEC) than petrol at the loading condition of the engine. The experiment also shows that LPG consumption at different loading was also lower than the petrol and found minimum at 50% of the load and at no load condition, consumption of LPG is comparatively lower than the consumption of petrol. For this experiment minor modification was required wherever done to run the engine by LPG without any problem using some necessary attachments like attachment for lubrication, etc. This article presents the comparative testing results of a two stroke, single cylinder, air cooled, modified, petrol engine operating on petrol and LPG. This comparative performance analysis shows that LPG is one of the better substitutes of petrol. Detailed comparative analysis of the engine performance using petrol and LPG has been made by the graph plotted between various parameters like Fuel Consumption (FC) and speed (RPM) for no load and for the different loading conditions, graphs between load and Fuel Consumption (FC), load and Brake Specific Fuel Consumption (BSFC), load and brake specific energy consumption (BSEC), and load and Brake Thermal Efficiency (BTE) and also done economic analysis. The present study shows that LPG is one of the better substitutes of petrol in terms of performance, consumption and cost.
