Summary:

The authors previously reported the performance of the "Stratified Charge Methanol Engine by Impingement of Fuel Jet (OSKA System) with Spark Plug Ignition." In that report, the impinging part was installed in the center of the piston cavity and a spark plug was used for ignition.In this report, the impinging part is installed on the cylinder head and a glow plug is used for ignition.A single-hole fuel injector (throttle type) is used. The centerline of the fuel injector coincides with that of the impinging part.A relatively low opening pressure (7.MPa) of the fuel injector is needed for this OSKA system. The fuel is injected against the impinging part, spreads and forms the fuel-air mixture.A glow plug is located just beside the impinging part.Experiments with a single-cylinder 4-stroke cycle prototype engine (bore stroke = 94 90 mm) showed that the maximum Brake Mean Effective Pressure (BMEP) was 1.04 MPa and the Maximum Brake Thermal Efficiency was 41.9 % (429.6 g/kW.h). The NOx emission was lower than that of the Diesel engine and the Unburnt Methanol was lower than that of the OSKA Methanol Engine with Spark Plug. Low combustion noise was observed and confirmed by the cylinder pressure analysis
