This paper presents a study of premixed combustion in a compression ignition (CI) engine. An electrically controlled fuel injection system was installed in the intake manifold of the engine. Dimethoxymethane (DMM) fuel with a low cetane number and low boiling point was injected into the manifold. The homogeneous mixture was formed in the compression stroke and ignited by a small amount of injected diesel fuel near the TDC (top dead centre). The effects of pre-mixed fuel ratio, engine load, CO2 concentration in the intake gas and nozzle hole diameter on the engine combustion and emissions were investigated. The results show that the pre-mixed combustion by DMM fuel port injection exhibits a substantial reduction of NOx and smoke emissions simultaneously, which might make it possible to develop a technique for controlling diesel engine exhaust emissions.
