Abstract
The step-down of petroleum fuels has forced researchers to identify alternative fuels in the industrial and transportation sectors to satisfy energy demands. The most frequently used fuel alternative in compression ignition engines is methyl esters derived from vegetable oils. The present work aims to examine the performance, combustion, and emission characteristics of corn oil blends in a variable-compression-ratio engine. The Corn bio-diesel blends B20, B40, B60, B80, and B100 were compared with diesel for compression ratios of 13:1 and 14:1. The same blends were used in the experiments. The results of various parameters, such as brake thermal efficiency, specific fuel consumption, and emissions, showed that B100 had better outcomes than diesel. The average cylinder pressure and heat release rate compared with those of different blends and diesel at a compression ratio of 14 were also used in this study.
