    Abstract: 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.

    Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection device with a control valve element keeping accurate opening/closing by preventing the entry of foreign matter into a displacement enlarging chamber.
    SOLUTION: The fuel injection device comprises an actuator and the displacement enlarging chamber 21 for enlarging the displacement of the actuator. The displacement enlarging chamber is communicated with a fuel passage via fuel resupply passages 16b', 16c' having check valves 22, 23 allowing the flow of fuel only into the displacement enlarging chamber, and the fuel resupply passage has a throttle portion 16c'.

    Abstract: PROBLEM TO BE SOLVED: To surely inject a fuel in a predetermined fuel injection mode in a fuel injection valve composed such that the injection mode is changeable. SOLUTION: The fuel injection valve is provided with a housing 3 having the first and second injection ports 4 and 5 at its tip part, a main valve element 1 housed in the housing to be liftable and a sub valve element 2 arranged between the tip part of the housing and the main valve element. When both main and sub valve elements are lifted in such a manner that they are detached from the inner wall of the housing, a fuel is injected from the first and second injection ports. Further, when the main valve element is lifted so as to detach from the housing inner wall in such a state that the sub valve element is seated thereon, the fuel is injected from the first port. Accordingly, the lifting operations of the main and sub valve elements can be controlled individually.

    Abstract: PROBLEM TO BE SOLVED: To attain both an improvement in mounting property and economic property and the ensuring of functional reliability in a fuel supply unit for an internal combustion engine having the function of additively supplying fuel as a reducing agent to a reduction catalyst provided on an exhaust system of the internal combustion engine and the function of accumulating the pressurized fuel once and injecting and supplying it to each cylinder. SOLUTION: In this fuel supply unit 10 for supplying each cylinder of the engine 100 and an exhaust passage 101, a device structure for arranging a control valve structure (suction shut-off valve) 80 containing a linear solenoid in a branch point branching a passage P2 for fuel sucked to a feed pump 30 to a fuel passage P3 directed to a fuel addition valve 40 and a fuel passage P4 directed to a high-pressure pump 50 is adapted. The suction shut-off valve 80 controls both the quantity of the fuel directed from the fuel passage P2 to the fuel passage P3 and the quantity of the fuel directed from the fuel passage P2 to the fuel passage P4 on the basis of an instruction signal from an electronic control unit(ECU).
