Zusammenfassung
(PT)
SISTEMA DE CONTROLE PARA MOTOR DE COMBUSTÃO INTERNA E MÉTODO DE CONTROLE. A presente invenção refere-se a um sistema de controle para um motor de combustão interna (1) em que o combustível contendo álcool é usado. No sistema de controle, a abertura máxima de uma válvula reguladora (3) no motor (1) é ajustada, e a abertura-alvo da válvula reguladora (3) é ajustada para um valor que é igual ou menor do que a abertura máxima. A abertura da válvula reguladora (3) é controlada de modo a coincidir com a abertura-alvo. A abertura máxima é de acordo com um parâmetro de concentração indicativo de uma concentração de álcool no combustível, um parâmetro de temperatura indicativo de uma temperatura do motor (1), e um número de ignições executadas depois da partida do motor (1).
