Abstract

MéTODO DE CONTROLE DE UM SISTEMA DE INJEçãO DIRETA DO TIPO TUBO COMUM PROVIDO DE UMA BOMBA DE COMBUSTìVEL DE ALTA PRESSãO. Trata-se de um método de controle de um sistema de injeção direta (1) do tipo tubo comum em um motor de combustão interna (2); o método de controle contemplando as etapas de: alimentar o combustível pressurizado a um tubo comum (5) por meio de uma bomba de alta pressão (6) apresentando pelo menos um elemento de bombeamento (15) operado mecanicamente por um eixo cardá (21) do motor de combustão interna (2); medir a posição angular do eixo cardã (21); medir a pressão de combustível (P~ rail~) no tubo comum (5); analisar as oscilações da pressão de combustível (P~ rail~) no tubo comum (5); e determinar a fase do elemento de bombeamento (15) da bomba de alta pressão (6) em relação ao eixo cardã (21) de acordo com as oscilações da pressão de combustível (P~ rail~) no tubo comum (5).
