Abstract
A method of predicting NOx generation amount of a compression ignition engine is provided. The method includes predicting a composition ratio of a gas in a mixture and a flame temperature using driving variables of an engine and calculating a nitrogen oxide generation rate using the composition ratio of the gas in the mixture and the flame temperature. Additionally, a nitrogen oxide generation concentration around flame is calculated using the nitrogen oxide generation rate and a total nitrogen oxide generation amount of a cylinder is predicted using the nitrogen oxide generation rate and the nitrogen oxide generation concentration.
