A PRESSURE-CHARGED GASOLINE INTERNAL COMBUSTION ENGINE

摘要

A pressure-charged gasoline internal combustion engine (200) comprising a combustion chamber (210, 211, 212) ; inlet valve means (i) ; exhaust valve means (a, b) ; a compressor (205) ; an intercooler (209) which receives compressed charge air from the compressor (205) ; an expander (220) which receives cooled compressed charge air from the intercooler (209) ; and an injector which injects gasoline directly into the combustion chamber (210, 211, 212) for mixing with the charge air conditioned previously by the compressor (205), the intercooler (209) and the expander (220). The compressor (205) is a supercharger.
