In the past research, the effect of close post injection strategy on engine-out emissions as various load conditions was evaluated. Close post injection strategy means the split injection strategy with the shortest dwell time between main and post injections for heavy EGR rate conditions. By using a close post injection strategy, ignition delay is prolonged due to the latent heat of post injected fuel and fuel stratification is improved. Therefore, combustion efficiency is improved due to lower CO and THC emissions and PM emission can be reduced drastically, with low NOx emission level (~10 ppm).
However, close post injection strategy does not always work well, so specific conditions would be satisfied to improve the effect of close post injection strategy on the reduction of engine-out emissions. Thus, in this research, the effect of close post injection strategy on the reduction of engine-out emissions as various EGR rate condition was evaluated. By analyzing rate of heat release, the result shows enough time to ignition delay is needed to avoid bad effect on emissions, so higher EGR rate condition is recommended to improve the force of this injection strategy.
