Based on the Closed Internal Combustion HCCI Engine Simulator model in CHEMKIN, this paper simulates the NOx emission of a four-stroke single-cylinder non-supercharged 135 diesel engine operating at different exhaust gas circulation rates and temperatures. Simulation experiments and analysis find that when the exhaust gas is cooled, the maximum temperature of in-cylinder combustion and the emission of NOx decrease with the increase of the exhaust gas circulation rate; when the recirculated exhaust gas is not cooled, the maximum temperature of the in-cylinder combustion barely changes with different exhaust gas circulation rates, and the NOx emission will not be greatly decreased.
