Simulation and experimental study of NOx emission control in direct injection diesel engine

Abstract

Diesel engines are the main prime movers for heavy duty vehicle applications worldwide Due to their fuel efficiency presently they are also used in light duty applications The pollutant emissions from diesel engines such as NOx and particulate matter are main contributors to environmental pollution Engine designers are striving to improve the fuel economy and to reduce the NOx emission from diesel engines Understanding the combustion in diesel engine will help the researchers to achieve these goals Computer simulation is considered as an important tool to understand the combustion and NOx formation in diesel engine Water injection into the combustion chamber of diesel engine was found to be one of the effective methods to simultaneously increase the fuel economy and to reduce the NOx and particulate matter emissions in diesel engine
