This book contains the successful experimental work to evaluate performance characteristics of a single cylinder-four stroke-water cooled compression ignition such as brake specific fuel consumption, brake thermal efficiency, and exhaust gas temperature for corn oil, corn oil methyl ester, corn oil ethyl ester and their blends with diesel. Similarly, emission characteristics such as CO, HC, CO2, and NOx have been compared for different test fuels as mentioned above. Finally, a comparison is made for performance and emission characteristics of diesel engine for RCO100, COME100, COEE100, and D100 test fuels. Key Features: Various Graphs and visuals for better understanding.
