The issue of inflation of petroleum products and exploitation of the petroleum reserves which are already at the extreme of getting abolished. Also, the Environmental concerns and fuel availability are significantly influencing fuel trends for transportation vehicles. Renewable fuels like biodiesel are ahead of other technologies to meet increasing energy demands. Additives are also used to improve ignition and combustion efficiency and elevate the engine performance. In the current study, it is attempted to optimize the brake thermal efficiency (BTE) and reduce the brake specific fuel consumption (BSFC) of cottonseed oil methyl ester by introduction of diethyl ether as an additive. In this investigation blend B20 is optimized for performance parameters by varying the percentage of diethyl ether additive as 4%, 5%, & 6% at different compression ratios i.e. 18 to 18. The BTE increased and BSFC decreased with the addition of diethyl ether in B20 blend for all the compression ratios 14-18. The highest BTE and and lowest BSFC were observed for B20+6% at compression ratio 16.
