Mixture Formation Analysis of a Schnurle-Type Two-Stroke Gasoline DI Engine 2001-01-1091
Because the two-stroke gasoline engine has a feature of high power density, it might become a choice for automobiles' power train if the high HC exhaust emissions and high fuel consumption rate could be improved. As the GDI technology is quite effective for two-stroke engines, a Schnurle-type small engine was modified to a GDI engine, and its performance was tested. Also, numerical analysis of the mixture-formation process was carried out. Results indicated it was possible to reduce both the HC emissions and fuel consumption drastically with the same maximum power as a carbureted engine at WOT condition. However, misfiring in light load condition was left unresolved. Numerical analysis clarified the process of how the mixture formation got affected by the injector location, injection timing, and gas motion.
