Abstract

trata-se de uma primeira válvula de injeção de combustível concebida para injetar combustível diretamente em uma câmara de combustão. quando uma condição de corte de combustível predeterminada é satisfeita, um corte de combustível, durante o qual a injeção de combustível pela primeira válvula de injeção de combustível é interrompida, é executado. quando uma condição de recuperação do corte de combustível predeterminada é satisfeita durante o corte de combustível, a injeção de combustível pela primeira válvula de injeção de combustível é reiniciada. quando do reinício da injeção de combustível após o corte de combustível, a pressão do combustível alimentado à primeira válvula de injeção de combustível aumenta acima de uma pressão de combustível em estado normal determinada de acordo com um estado de acionamento. com isso, é possível promover a atomização e vaporização do jato quando do reinício da injeção de combustível, além de suprimir a quantidade de descarga dos particulados de escapamento e o número de descarga dos particulados de escapamento.
