ンジン。 A compressor directly connected to a turbine driven by exhaust gas compresses intake air and supplies it into the cylinder, and a fuel injection pump pumps pressurized fuel into the cylinder through a fuel injection nozzle. In a turbocharged engine, the fuel injection pump is injected sequentially, and a boost compensator is attached to the governor of the fuel injection pump, and when the boost pressure is low, the control rack of the fuel injection pump is pulled back to suppress the amount of fuel injected. , a solenoid valve is attached to the boost compensator or a conduit connected to the boost compensator, and an abnormality detection means is provided, and the solenoid valve is opened in response to detection by the abnormality detection means. A turbocharged engine.
