| Abstract: | An in-cylinder gasoline direct injection (GDI) engine, incorporating novel combustion technologies, has been developed. Such innovative technologies consist of the upright straight ports to generate tumble motion, the electro magnetic swirl injector to realize optimized spray dispersion and atomization and the compact piston cavity to maintain charge stratification, and in addition other highly advanced technologies to achieve desirable engine management. This new GDI engine is thus available with ultra lean stratified combustion for higher thermal efficiency under partial loads as well as homogenous combustion to realize higher performance under full load. |
