Abstract

DISPOSITIVO PARA SUPRIMENTO DE COMBUSTìVEL PARA UM MOTOR DE COMBUSTãO, MéTODO PARA OPERAçãO DO REFERIDO DISPOSITIVO E DISPOSITIVO PARA CONTROLE DA OPERAçãO DE UM MOTOR DE COMBUSTãO. A invenção se refere a um método usados para suprimento de combustível para um motor de combustão. O método envolve a abertura do injetor de gás para a injeção de combustível gasoso em um motor de combustão, a abertura da válvula de comutação quando a pressão no volume de injetor cair abaixo de uma primeira pressão e o fechamento da válvula de comutação quando a pressão no volume exceder a uma segunda pressão, a segunda pressão sendo mais alta do que a primeira pressão.
