Performance and emission characteristics of a diesel engine runs with corn oil biodiesel blends and air pre-heater

Abstract

The demand of diesel fuel has been increasing all over the world. To overcome this energy demand, an alternative fuel or biodiesel is the need of the hour. The objective of this work is to investigate the CI engine performance and emission parameters using corn oil Methyl Ester biodiesel fuel. The engine performance characteristics such as thermal efficiency, brake specific fuel consumption (BSFC), and exhaust emissions such as CO2, HC, NOx and particulate matter were evaluated. In this experimental work, the diesel engine performance and emission parameters have been investigated with two different inlet air temperature of 35°C and 50°C for different bio diesel blends like 100% D, 90% D+10% CME (Corn oil Methyl Ester), 80% D+20% CME, 70% D+30% CME and 60% D+40% CME. Air pre-heater has been designed to preheat the inlet air by using the waste exhaust heat energy coming out of the engine. Higher inlet air temperature causes reduction in the fuel consumption and increasing the thermal efficiency. Corn oil blends with diesel with or without preheating of inlet air can be used in CI engines for obtaining improved engine performance and lower emissions.
