IPC: F02M47/00
Filed: 1988-01-28
Abstract: PURPOSE:To perform the fuel injection even if the fuel injection by the electronic control method becomes difficult by providing bypass pipes and fuel passage selector valves. CONSTITUTION:When one of devices provided between pipes 50, 52 functionally fails and the fuel injection or its control becomes difficult, passage directions of selector valves 45, 46 are switched so that pipes 49, 54, 53 are communicated and pipes 49, 50 and pipes 52, 53 are cut off. In addition, a selector switch 48 normally connecting cables 59, 61 is switched so as to connect cables 60, 61 and cut off cables 59, 61. Accordingly, a fuel pump 18 is a normal plunger type pump and a fuel injection valve 38 is a normal automatic injection valve, thus the fuel injection can be performed only by switching the fuel passage via the selector valves 45, 46 and the pipe 54. A discharge quantity adjusting device 19 is controlled by a governor 47 through the cables 60, 61.
