Compression self-igniting gasoline engine

摘要: Stroke cycles of a self-igniting gasoline engine (10) comprising an intake stroke, compression power stroke and exhaust are performed sequentially by piston (12), self ignition the fuel mixture is in stroke. The strokes (12) detected sensor (23), electronic control unit (1) controls valve timing adjustment mechanism (15, 18) so that sealed period occurs when both (17) (14) closed vicinity top dead center also injection injector (19) injected into combustion chamber (11) during period. hot gas causes pre-combustion reactions, thereby modifies composition to more reactive containing aldehydes self-ignition easily.
