Experimental Analysis of the Effect of Exhaust Gas Recirculation (EGR) on Engine Performance and Exhaust Emissions on Diesel Engines

When the temperature of the combustion chamber rises beyond 1800 K in internal combustion engines, the nitrogen and oxygen in the air combine chemically and become a gas called nitrogen oxide, which is harmful to human health and the environment. Nitrogen oxides combine with humidity in the lungs and become nitric acid, which causes breathing illnesses. Diesel engines use excess air for combustion…
