A Study on the Effects of EGR on the Performance of Bio-Diesel Engines

Article Preview

Abstract:

Effects of EGR on the performance of bio-diesel engine were studied on a single-cylinder bench. The results showed that EGR can reduce NOx emission and NOx reduction increased with EGR rate. When EGR increases too much, due to the deterioration of combustion, CO and HC emission increased distinctly. When the EGR rate is lower than 25%, CO, HC and PM emissions increasing is tolerable, which means that 25% EGR rate can be used to improve NOx emission of bio-diesel engine.
