Abstract

CONTROLE DE PRESSAO DE COMBUSTIVEL. Um método de alívio de pressão de mergulho a quente em uma flauta de combustível de um motor de combustão interna de combustível injetado inclui a pressurização de combustível com uma bomba de combustível, quando o motor estiver operando, e o transporte do fluido pressurizado através de uma válvula de retenção que impede um fluxo de retorno de combustível a partir da flauta de combustível em direção à bomba de combustível. Um percurso de desvio está em comunicação de fluido entre uma localização a jusante da válvula de retenção e uma localização a jusante da bomba de combustível e a montante da válvula de retenção. O percurso de desvio é aberto quando o motor não estiver operando, de modo a se aliviar a pressão de combustível a jusante da válvula de retenção para um nível abaixo de uma pressão de operação de sistema. São providos aparelhos para a realização do método.
