Abstract

dispositivo de controle de motor de combustão interna a invenção refere-se a um dispositivo de controle de um motor de combustão interna para calcular, com base na diferença da relação ar-combustível, uma correção para a correção de quantidade de fornecimento de combustível estimada, para corrigir a quantidade de fornecimento de combustível estimada fazer a relação ar-combustível estimada corresponder à relação ar-combustível detectada, calcular os valores de correção para a compensação de diferença de fornecimento de combustível e a compensação de diferença de detecção de quantidade de ar através da divisão do valor de correção pela correção de quantidade de fornecimento de combustível estimada, usando as proporções de diferença de detecção de quantidade de ar e fornecimento de combustível, e executar o controle da razão de ar-combustível, usando as quantidades de ar detectadas e de fornecimento de combustível estimadas corrigidas por esse valor de correção. nesta invenção, o valor de correção para a correção da quantidade de fornecimento de combustível estimada é dividido pelos valores de correção para a compensação de diferença de fornecimetno de combustível e para a compensação de diferença de detecção de quantidade de ar de modo que um valor equivalente à diferença de relação ar-combustível se torne igual à diferença de relação ar-combustível, usando esses valores de correção.
