Abstract

DISPOSITIVO DE CONTROLE DE INJEçãO DE COMBUSTìVEL PARA MOTOR DE COMBUSTãO INTERNA E VEìCULO DO TIPO DE MONTAR PROVIDO COM O MESMO. [Problema] - Permitir um dispositivo de controle de injeção de combustível capaz de suprir um motor de combustão interna com uma quantidade apropriada de combustível mesmo no caso em que uma proporção de mistura de álcool varia para ser colocada em prática sem complicação excessiva de uma estrutura do mesmo. [Meios para Solução] - Uma ECU de uma motocicleta inclui uma parte de cálculo 201 para calcular um coeficiente de correção de realimentação de 02 com base em um valor detectado de um sensor de O~ 2~ 56, uma parte de cálculo 202 para calcular uma proporção de mistura de etanol de um combustível misturado com base no coeficiente de correção de realímentação de O~ 2~, uma parte de cálculo 203 para calcular uma proporção de ar-combustível teórica do combustível misturado e uma parte de cálculo de coeficiente de reflexão 300. A parte de cálculo de coeficiente de reflexão 300 armazena vários valores determinados de um coeficiente de correção de proporção de ar-combustível determinado com base na proporção de mistura de etanol e temperatura de um motor. Os valores determinados do coeficiente de correção de proporção de ar-combustível são usados para realizar o cálculo de interpolação de um valor do coeficiente de correção de proporção de ar-combustível refletindo uma proporção de mistura de álcool calculada por meio da parte de cálculo 202 e a temperatura do motor detectada por meio do sensor de temperatura. Uma proporção de ar-combustível alvo é calculada com base no valor calculado de coeficiente de correção de proporção de ar-combustível, usando a proporção de ar-combustível teórica.
