Abstract

"SISTEMA DE CONTROLE DE ADMISSãO PARA MOTOR DE COMBUSTãO INTERNA". Fornecer um sistema de controle de admissão para um motor de combustão interna com o qual é possível impedir um aumento no custo e impedir efeitos adversos nas características de partida do motor de combustão interna. No momento de executar um ajuste de posição de referência de uma válvula de controle de fluxo de ar de admissão auxiliar, onde tanto uma primeira condição de releitura onde o valor absoluto da diferença entre uma velocidade alvo de marcha lenta do motor e uma velocidade atual de marcha lenta do motor é menor do que um primeiro limite quanto uma segunda condição de releitura onde o valor absoluto da diferença entre uma taxa de fluxo de admissão calculada e uma taxa de fluxo de admissão de referência é maior do que um segundo limite são estabelecidas, a etapa S5 é executada na qual uma abertura de válvula que corresponde à taxa de fluxo de ar de admissão de referência em uma base de característica de referência é utilizada no lugar de uma abertura de válvula que corresponde à taxa de fluxo de admissão calculada."ADMISSION CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE". Provide an intake control system for an internal combustion engine with which it is possible to prevent an increase in cost and to prevent adverse effects on the internal combustion engine starting characteristics. When performing a reference position adjustment of an auxiliary intake airflow control valve where both a first reread condition where the absolute value of the difference between a target engine idle speed and a current engine idle is less than a first limit as a second reread condition where the absolute value of the difference between a calculated inlet flow rate and a reference inlet flow rate is greater than a second limit is established, Step S5 is performed in which a valve opening that corresponds to the reference intake air flow rate on a reference characteristic basis is used in place of a valve opening that corresponds to the calculated intake flow rate.
