Abstract

dispositivo de controle para motor de combustão interna e método de controle para este. um período de sobreposição (o/l) de válvula entre uma válvula de admissão e uma válvula de exaustão do motor de combustão interna é estabelecido para incluir um período após um ponto morto superior de exaustão e a temporização final de injeção de uma válvula de injeção de combustível que injeta combustível em uma porta de admissão que é aberta e fechada pela válvula de admissão é estabelecida de modo que o combustível injetado a partir da válvula de injeção de combustível na temporização final de injeção flua para uma câmara de combustão durante uma parte do período de o/l de válvula que é após o ponto morto superior de exaustão.control device for internal combustion engine and control method for it. a valve overlap period (o/l) between an inlet valve and an exhaust valve of the internal combustion engine is established to include a period after an exhaust top dead center and the final injection timing of an injection valve system that injects fuel into an inlet port that is opened and closed by the inlet valve is set up so that fuel injected from the fuel injection valve at the final injection timing flows into a combustion chamber during a portion of the valve o/l period which is after exhaust top dead center.
