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.

摘要： PROBLEM TO BE SOLVED: To prevent an error from occurring in an injection time of a fuel injection valve.
SOLUTION: A primary piston 303a is displaced by a piezoactuator 303, and the displacement of the primary piston is transmitted to a secondary piston 300a via oil in an oil pressure chamber 301, so that the displacement of the primary piston is amplified to be transmitted to the secondary piston, and the secondary piston actuates a control valve 300 to inject fuel. When the oil quantity leaked from the oil pressure chamber after completing the injection fills the oil pressure chamber via a check valve which allows only a flow of the fuel heading from a low pressure fuel passage 213 to the oil pressure chamber, it is so set that an opening valve differential pressure of the check valve becomes larger as the displacement of the secondary piston becomes larger, so as to prevent the excessive filling of oil of the oil pressure chamber.
