Abstract

resumo "dispositivo de controle de injeção de combustível e método de controle de injeção de combustível para motor de combustão interna" trata-se de um motor de combustão interna que inclui um injetor de porta que injeta combustível em uma porta de admissão e um injetor de injeção direta que injeta combustível diretamente em uma câmara de combustão. quando o motor de combustão interna está em uma condição de carga baixa enquanto requer injeção de combustível, um controlador interrompe a injeção de combustível através do injetor de porta de modo que uma quantidade de injeção de combustível necessária inteira seja injetada através do injetor de injeção direta. como resultado deste proces-samento, a pressão de combustível do injetor de injeção direta é reduzida rapidamente na condição de carga baixa.
