Abstract

UNIDADE DE CONTROLE DE MOTOR A COMBUSTìVEL FLEXìVEL. Ao dar partida a um motor a combustível flexível (10), que utiliza combustível principal à base de álcool e combustível auxiliar à base de gasolina, se o motor (10) está em uma condição desfavorável para iniciar a combustão é determinada com base na saída de um sensor de temperatura de motor (30) e a saída de um sensor de concentração de álcool (39) que detecta a concentração de álcool na vizinhança de uma abertura de admissão (16). Quando se determina que o sensor de temperatura de água (30) está defeituoso por uma unidade de detecção de defeito (35), uma unidade de controle de injeção de combustível (36) forçadamente executa o controle de alimentação de combustível de o combustível auxiliar.
