The pump-pipe-injector system is that most commonly used type of injection equipment for diesel engines. In this study, a new electromagnetic fuel injection system was designed and carried out the experiment of single cylinder direct injection(DI) diesel engine. This system do not need the earn shaft for fuel injection. The effects of the injection timing on the combustion process and and emission were investigated. The results are that 1) atomization was improved, 2) combustion pressure was increased and ignition delay became shorter than before, 3) Low smoke level guar-antee with more advanced injection timing without abnormal combustion but NOx concentration was increased as the injection time advanced.
