Fuel Effect on Reciprocating Engine Performance 860085

A single cylinder reciprocating engine test rig was used to measure power output, specific fuel consumption, exhaust gas temperature and energy balance for different speeds, air-fuel ratios and compression ratios with gasoline and diesel as fuels. Comparison of the results for the same compression ratios and range of running speeds shows that gasoline produces higher power and exhaust temperatures than diesel. However, it produced less thermal efficiency up to 2000 rpm speed. Energy balance shows slightly higher percentage in power and exhaust energy but markedly less radiation energy to the atmosphere with diesel.
