Summary:

The new type of Diesel combustion engine has been developed.The new Idea Incorporates an impingement part in the central piston cavity. The fuel jet is injected against the impingement part, spreads and form fuel-air mixture.Single hole fuel injection nozzle is used and the relatively low opening pressure is needed. Intake air swirl is not needed.The re-entrant type combustion chamber is employed to get a relatively strong squish speed. Experimental with single cylinder 4 stroke prototype test engine showed that the brake mean effective pressure was 0.82 MPa and the maximum net specific fuel consumption was 220 g/kW.h. The NOx and smoke emissions was reduced compared with the conventional DI Diesel engine.The authors have developed a new type of Direct Injection Stratified Charge SI engine called "Direct Fuel Injection Impingement Diffusion Stratified Charge System" (hereafter called OSKA). The authors have already reported on the performance and exhaust emissions of the methanol and gasoline spark ignition version 4 stroke engines utilizing this OSKA system(1), (2), (3) and (4)*.Now, the authors report about development of OSKA Diesel version (OSKA-D)
