Research on the Stratified Charge Control of the Nitrogen-Enriched Intake Air

Abstract:

Nitrogen-enriched intake air (NEA) can reduce the formation of NOx by inhibiting the combustion temperature in cylinder. This paper discusses the research progress on engines using NEA. The result indicates that nitrogen-enriched air can reduce engine NOx emissions remarkably. Besides, this paper analyzes the basic characteristics of the stratified charge control of the nitrogen-enriched intake air. In order to optimize the nitrogen stratification charge, a new nitrogen direct injection engine of stratified charge has been designed.
