Abstract

This paper presents, the performance comparison between carburetor and Multi-point Fuel-Injection (MPFI) spark ignition (SI) engines for different blends of gasoline-ethanol. Ethanol from biomass is an ecologically sustainable fuel for automobile engines. In this work, tests were conducted on both carburetor and MPFI SI engines under different loads for all blends. For each blends reading were taken for varying load. The analyses were conducted using gasoline-ethanol blends with the volumetric ratio of 0% to 50% with an increment of 5% ethanol. The performance parameters such as air-fuel ratio, brake thermal efficiency, volumetric efficiency, fuel consumption and mechanical efficiency were done for both the engine under condition. The results show that at 20% ethanol blend with gasoline both the engine gives better performance. However, the MPFI SI engine provides better results than the carburetor SI engine.
