Abstract

dispositivo de controle de injeção para combustível de motor de combustível de tipo múltiplo. a presente invenção refere-se a um dispositivo de controle de injeção de combustível de motor de combustível de tipo múltiplo, que inclui uma pluralidade de mapas para determinar um tempo de injeção de combustível básico que corresponde a um estado de um motor e troca o mapa que corresponde à concentração de álcool. um dispositivo de controle de injeção de combustível utilizado em um motor de combustível do tipo múltiplo (1) é configurado para incluir: uma região de memória (26) que armazena uma pluralidade de mapas de controle de injeção de combustível (30) nos quais um estado de um motor (1) e um tempo de injeção de combustível básico (ti) são feitos para corresponder um com o outro em resposta à concentração de álcool contido no combustível; um sensor de o~ 2~ (15) que é arranjado em um tubo de descarga (4) e detecta a concentração de oxigênio em um gás de descarga; uma parte de determinação de tempo de injeção de combustível básico (22) que determina o tempo de injeção de combustível básico (ti) utilizando o mapa de controle de injeção de combustível selecionado atualmente (30) da concentração de álcool; uma parte de determinação de coeficiente de correção (24) que determina o coeficiente k~ 02~ de correção de relação de ar-combustível para corrigir o tempo de injeção de combustível básico (ti) de tal modo que uma relação de ar-combustível do motor (1) se torna uma relação de ar-combustível objetivada em resposta a um valor de detecção do sensor de o~ 2~ (15); uma parte de determinação de quantidade de injeção de combustível (25) que determina uma quantidade de injeção de combustível com base no tempo de injeção de combustível básico (ti) e o coeficiente de correção da relação de ar-combustível k~ o2~; e uma parte de troca de mapa (21) que seleciona o mapa de controle de injeção de combustível (30) da concentração de álcool próxima à concentração de álcool do combustível com base no coeficiente de correção da relação de ar-combustível k~ o2~.
