Abstract
The emission, performance and ignition characters of a four stroke single cylinder variable CR (compression ratio) multi fuel engine when energized with mahua methyl ester and its 20%, 40%, 60% furthermore, 80% mixes with diesel (on a volume Basis). The mahua methyl ester as a bio-fuel has been set up in this investigation. Bio-diesel produced from transesterification process has been utilized as a part of this investigation. Trial has been carried at a constant engine speed of 1500 rpm, 50% load and at CR (compression ratio) of 14: 1, 16.38: 1 and 17.5: 1. The effect of CR on fuel utilization, combustion pressure furthermore, exhaust emission has been researched and displayed. Ideal pressure proportion which gives best execution has been distinguished. The outcomes show higher ignition delay, raise in pressure, heat relies rate is lower at higher CR for mahua methyl ester when contrasted with that of diesel. The brake thermal efficiency of mahua methyl ester blends and diesel has been computed and the B20 is found to give most BTE. The different blends when utilized as fuel bring about reduced emissions of carbon monoxide, hydrocarbon and increment in nitrogen oxides.
