Abstract

CONTROLADOR DE MOTOR DE COMBUSTãO INTERNA. Um controlador de um motor de combustão interna inclui: um controlador de purga, operável para controlar uma quantidade de purga do combustível vaporizado purgado pra o sistema de entrada de ar; um detector de relação de ar de exaustão-combustível; um controlador de realimentação de relação de ar-combustível; um determinador de período, operável para determinar se é um período de permissão de estimativa; e um estimador de concentração de álcool, operável para estimar a concentração de álcool. Quando a purga do combustível vaporizado é interrompida durante o período de permissão de estimativa, o controlador de purga: realiza o controle de modo que a purga é interrompida com um grande grau de tailing, em uma região de operação onde uma carga do motor de combustão interna é alta e uma velocidade de rotação é alta; e realiza o controle de modo que a purga é interrompida com um pequeno grau de tailing que o grau maior de tailing, em uma região de operação onde a carga do motor de combustão interna é baixa e a velocidade de rotação é baixa.
