Abstract

The experimental investigation was led for a better understanding about the reduction of exhaust emissions in CRDI diesel engine such as NOx, HC and CO employing the multiple injection strategies. Two multiple injection strategies were used: pilot injection and split injection. It was revealed that maximum value of combustion pressure in two pilot injections was increased to almost the same level of single injection combustion although its maximum heat release rate (HRR) was decreased compared to single injection combustion. It was also observed that two pilot injections improves combustion efficiency, based on the results of increased IMEP (0.8% and 2.4% under medium and high load respectively). Moreover, in early pilot injection combustion, more CO formation and less HC emission were observed during combustion process. Reduction of NOx up to 22.23% and 6.7% was recorded under medium and high load.
