Abstract
SISTEMA DE INJEÇÃO DE COMBUSTÍVEL DE MOTOR DE COMBUSTÃO INTERNA DE VEÍCULO. A presente invenção refere-se a um método para se permitir o controle de modo que a razão adequada de ar para combustível seja também adquirida quando uma válvula de ultrapassagem (24) que controla uma taxa de fluxo de ar de entrada que flui em uma passagem de ultrapassagem (23) para ultrapassar uma válvula de aceleração (21) é aberta de modo a aumentar a taxa de fluxo de ar de entrada em um sistema de injeção de combustível de um motor de combustão interna (E) de veículo que prescreve a quantidade básica de injeção de combustível para tornar a razão de ar para combustível a razão-alvo de ar para combustível com base em uma abertura de aceleração e executa o controle de injeção de combustível para que seja a quantidade de injeção de combustível adquirida pela correção da quantidade básica de injeção de combustível com um valor aprendido de acordo com um valor detectado por um sensor de oxigênio (32). Uma unidade de controle (C) corrige a quantidade de injeção utilizando um primeiro valor aprendido influenciado pela abertura de aceleração com relação ao ar de entrada passando pela válvula de aceleração (21) e fluindo em uma passagem de entrada (17) e corrige a quantidade de injeção utilizando um segundo valor aprendido não relacionado com a abertura de aceleração com relação ao ar de entrada fluindo na passagem de ultrapassagem (23).VEHICLE INTERNAL COMBUSTION ENGINE FUEL INJECTION SYSTEM. The present invention relates to a method of enabling control so that the proper ratio of air to fuel is also acquired when a bypass valve (24) which controls a flow rate of inlet air flowing in a passage (23) to bypass an throttle valve (21) is opened so as to increase the rate of flow of inlet air into a fuel injection system of a vehicle internal combustion engine (E) which prescribes the amount basic fuel injection to make the air to fuel ratio the target air to fuel ratio based on a throttle opening and run the fuel injection control to be the amount of fuel injection gained by correcting the amount basic fuel injection with a learned value according to a value detected by an oxygen sensor (32). A control unit (C) corrects the injection amount using a first learned value influenced by the throttle opening with respect to inlet air passing through the throttle valve (21) and flowing in an inlet passage (17) and corrects the amount injection using a second learned value unrelated to the throttle opening with respect to inlet air flowing in the overtaking passage (23).
