Development of a 3.0 L DI Diesel Engine to Meet Euro III Emission Norms

Extensive research is in progress to reduce both nitrogen oxides (NOx) and particulate (soot) emissions from diesel engines due to environmental considerations. The present work was aimed at demonstrating the capabilities of direct injection diesel engine with an electronically controlled distributor type fuel injection pump to meet stringent emission norms of Euro III.

Emission and performance results are presented from an experimental study done on a 3.0 l DI diesel engine. The mass measurements of particulate emission are based on measurements of smoke and HC emissions, which provides a less expensive way of carrying out preliminary combustion optimization work. It is concluded that higher spray penetration with the help of advanced nozzle technology coupled with advanced fuel injection pump technologies with electronic control and with the optimum combustion system a significant reduction of soot and NOx emissions can be obtained. The understanding gained from the experiments can be used for optimizing diesel combustion systems for improved emissions and fuel consumption in a faster and more efficient manner
