Abstract

"MéTODO DE INJEçãO DIRETA DE COMBUSTìVEL EM MOTOR A COMBUSTãO INTERNA". Em que uma bomba de alta pressão (4) com velocidade de fluxo variável fornece o combustível a um trilho comum (3) que, por sua vez, fornece o combustível a uma série de injetores (2); a velocidade de fluxo da bomba de alta pressão (4) é controlada pela sufocação de cada impulso de bomba através da variação do tempo de fechamento de uma válvula de entrada (16) da mencionada bomba de alta pressão (4); o acionamento mecânico da bomba de alta pressão (4) é programado de tal forma que cada intervalo de injeção (1) esteja localizado no início de uma ação de sufocação correspondente e cada impulso de bomba seja sufocado pelo menos em intervalo angular que possua duração de não menos que os intervalos de injeção (1), independentemente da quantidade de combustível a ser fornecida ao trilho comum (3), de tal forma que a fase de injeção de cada injetor (2) sempre tenha lugar quando a bomba de alta pressão (4) não estiver bombeando combustível para o trilho comum (3).
