Title Study of direct injection and pre-chamber application in light duty gaseous fuel engines
Author(s) Mazlan, S

Abstract The application of pre-chamber in lean combustion proved to promote fast combustion and produce high thermal efficiency. This research demonstrated the potential of pre-chamber and direct injection in gaseous fuel engine in terms of engine performance.The research provided better understanding of combustion and mixture formation in CNG engine with pre-chamber ignition system and direct fuel injection strategy. This research demonstrated that the fuel injection timing (early and late) has significant effects on lean limit as late fuel injection enable the lean limit to be extended. In pre-chamber application, the performance of passive pre-chamber is affected by the geometry of the pre-chamber, location of the ignition source and the mixture in the main chamber.

This research contributes to an insight for a successful system to produce a faster combustion in natural gas fuelled engines.
