Abstract

resumo patente de invenção: "dispositivo de controle para um motor de combustão interna que usa um combustível no qual álcool é misturado". a presente invenção refere-se a um dispositivo de controle de motor de combustão interna para um motor de combustão interna de injeção dupla que obtém um primeiro e segundo valores de aumento, que vêm a ser as razões de aumento de combustível de acordo com as respectivas concentrações de álcool de um combustível injetado por uma injeção de cilindro (dl) e de um combustível injetado por uma injeção de orifício (pfi). o dispositivo de controle determina uma quantidade de injeção total básica de combustível (total) que deve ser suprida para cada cilindro no caso em que a concentração de álcool no combustível é zero. uma quantidade de combustível injetado a partir de uma válvula de injeção de cilindro (quantidade equivalente à e0 da injeção dl) é determinada como se a concentração de álcool no combustível fosse zero. uma quantidade total de injeção deve corresponder a uma quantidade de acordo com a quantidade de injeção total básica (total) e a ambos o primeiro valor de aumento e o segundo valor de aumento, de modo que o aumento na quantidade de combustível injetado seja suportado pela injeção de orifício (pfi). 1/1
