摘要： The purpose of the present invention is to provide a diesel engine that can be smoothly started even in a situation where a plunger has become difficult to rotate due to sticking of the plunger that is caused by a fuel film formed on the outer periphery of the plunger. When a key switch 80 is operated from an off-position to an on-position, a control unit 70 of this diesel engine 1 controls an actuator 48 so as to cause a rack 45 to perform a predetermined operation X. If the rack 45 cannot complete the predetermined operation X within a predetermined amount of time Ta, on condition that the key switch 80 is held at a start-position, the control unit controls a starter 60 so as to cause a plunger 34 to perform a preparatory stroke operation whereby the plunger 34 is caused to perform a stroke operation, and the stroke operation by the plunger 34 is stopped before the diesel engine 1 starts.

摘要： A device (10) for controlling the speed of an internal combustion engine comprising a control lever (20) movably associated to a support element (11), which may be the engine casing (101) or a portion thereof. The control lever (20) is moveable at least between a first position, in which the engine is at a first rotation regime, and a second position, in which the engine is at a second rotation regime. A selective locking mechanism (51,521,522) is provided that prohibits the control lever (20) from being stably positioned at any (and all) intermediate positions between the first and second positions. In one embodiment, a biasing force generated by the device (10) automatically forces the control lever (20) into one of the first or second positions when the control lever (20) is located in any of the intermediate positions and an actuation force is ceased.

摘要： An engine (1) is a diesel engine, where a roller (80) that is a rolling body for a tappet for driving a plunger (84) is brought into contact with a cam (21) on a camshaft (13), and thereby a fuel injection pump (12) is driven. A roller tappet (82) supporting the rolling body is provided on a tappet guide (91) that is a projection for limiting the swing of the support portion. Further, a guide groove (92) in which the projection fits is provided in a slide portion (2b) that slidably fits on the support portion. The structure above enables the rolling body and the cam that is in contact with the rolling body to be prevented from wearing, and also enables slide stroke control of the plunger to be maintained at high accuracy.

摘要： The invention relates to a fuel injection device comprising a fuel pump embodied as a double piston pump which is used to pump fuel into the combustion chamber of an internal combustion engine to an injector respectively associated therewith and which is optimized with regard to the injection process thereof. The double piston pump comprises two pistons (70, 73) which pump in parallel along a common line and which are provided with control edges. A control rod (71,74) is associated with each piston (70,73) and is used to control the beginning and end of the pumping. The beginning of the pumping can be adjusted on the first piston (70) and the end of the pumping can be adjusted on the second piston (73). A control pressure is provided prior to the beginning of injection according to engine operation parameters in order to adjust the force acting upon the injector needle (12) in the direction of closure, said pressure enabling pressure to be impinged upon the valve needle (12) in the direction of closure. In order to compensate an alteration in the beginning of injection caused thereby, the control rod (71) of the first piston (70) regulating the beginning of pumping is adjusted accordingly.
