Abstract

DISPOSITIVO DE CONTROLE PARA INJEçãO DE COMBUSTìVEL. A presente invenção fornece um dispositivo de controle para injeção de combustível de um motor de combustão interna de diversos tipos de combustível, que pode realizar um controle de suprimento de combustível átimo e estável em resposta a relações de mistura de diversos tipos de combustíveis e ao mesmo tempo encurta o tempo de partida e impede a cobertura da vela. Uma ROM 23 de uma ECU 10 armazena uma pluralidade de mapas de quantidade de injeção de combustível de referência que correspondem a concentrações de mistura de combustíveis de diversos tipos. Um programa de controle da CUP 21 armazena que mapa é utilizado a partir da pluralidade de mapas de quantidade de injeção de combustível de referência na EEP-ROM 24, realiza um controle de partida de um motor utilizando o mapa de quantidade de injeção de combustível de referência que é utilizado imediatamente antes do tempo de uma parada precedente no tempo de iniciar a partida com base em mapas armazenados e, ao mesmo tempo, realiza o controle de partida aumentando gradualmente a quantidade de injeção de combustível até que a partida de um motor seja esteja terminada.
