When it is determined by the determination means 16 that the exhaust emission control device 17 is damaged, the exhaust throttle valve 10 is fully opened. Thereby, even when the broken pieces of the damaged exhaust emission control device 17 are made to flow into the downstream side of the exhaust passage 9, the broken pieces are passed through without being accumulated in the exhaust throttle valve 10. Therefore, closing of the exhaust passage 9 by the broken pieces is suppressed. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a diesel engine lubricated with fuel such as diesel oil, for lubricating an engine lubrication system or the like, early consuming fuel susceptible to mixing of a dirty component such as soot therein, and efficiently cleaning exhaust. SOLUTION: The diesel engine 1 lubricated with fuel such as diesel oil has a fuel adding means (fuel adding valve 25) for adding the fuel to a diesel catalyst 24 disposed to an exhaust system. The fuel added by the fuel adding means 25 functions as additive for NO x reduction or additive of increasing catalyst temperature in the diesel catalyst 24. Since the fuel containing soot or the like supplied to the engine body 7 of the diesel engine 1 lubricated with fuel such as diesel oil can be consumed early, the effect on a component of an injection system such as an injection pump and a fuel injection valve is mitigated.
