Abstract
This paper analyzes the impact of nitrogen enriched air on emissions, in cylinder pressure, heat released during the working cycle and fuel consumption of a diesel engine. The experiment was performed on a naturally aspirated single cylinder diesel engine by increasing the nitrogen concentration supplied through a cylinder and NOx, CO, THC emissions were all measured with the help of a five gas analyzer. It was observed that enriching the inlet air with nitrogen decreases the NOx concentration considerably with a penalty on hydrocarbon emissions and thus the fuel conversion efficiency.
