Abstract

resumo patente de invenção: "aparelho de determinação de anormalidade e método de determinação de anormalidade para sistema de suprimento de combustível". este aparelho detecta, durante um período de detecção de um tempo intermediário (um ponto no tempo t11) entre respectivos tempos de ponto morto superior de compressão de dos dois cilindros que são sucessivos um ao outro em sequência de ignição para um tempo (um ponto no tempo t12) imediatamente antes do início de injeção de combustível naquele destes cilindros o qual é o último na sequência de ignição, uma pressão de combustível por um sensor de detecção de pressão que está provido em um modo que corresponde ao cilindro que é o último na sequência de ignição, e determina, com base em uma velocidade de diminuição na pressão de combustível pq detectada, se ocorreu ou não uma anormalidade de vazamento de combustível.
