Abstract

aparelho de injeção de combustível para motor à combustão interna. a presente invenção refere-se a um aparelho de injeção de combustível para um motor à combustão interna que usa um combustível misturado de gasolina e álcool, que é fornecido. o aparelho de injeção de combustível é capaz de inibir, com uma estrutura simples, que emissões sejam pioradas durante o uso do combustível misturado. o aparelho de injeção de combustível inclui: um injetor de combustível (26) que tem uma parte de extremidade frontal (261) que tem um espaço interno (263) no qual o combustível é acumulado e tem uma porta de injeção (262) para injetar combustível; e um adsorvente (58) disposto no espaço interno (263), em que o absorvente (58) é capaz de absorver seletivamente um componente de álcool em um combustível misturado de gasolina e álcool. o aparelho de injeção de combustível controla uma quantidade de injeção do injetor de combustível (26) de modo que uma relação arcombustível de um motor à combustão interna (10) seja uma relação arcombustível alvo controlada baseado em uma concentração de álcool de um combustível misturado fornecido para injetor de combustível (26) (a primeiraconcentração de álcool). neste aparelho de injeção de combustível, uma pressão de combustível é trazida para uma pressão alta predeterminada de combustível durante a partida fria do motor à combustão interna (10). neste momento, uma quantidade adsorvida de álcool no absorvente (58) é estimada e qualquer desvio na relação ar-combustível do motor à combustão interna (10) é corrigido baseado na quantidade adsorvida de álcool.
