摘要： In one embodiment, a small-diameter opening (42b) is formed in the central portion of a valve element (42) included in a check valve (40) of a high pressure fuel pump (1). A needle valve (44) is provided integrally with a valve element (35a) of an electromagnetic spill valve (30), and the opening (42b) of the valve element (42) can be opened and closed with a tip portion of the needle valve (44). When the high pressure fuel pump (1) switches from the drive state to the stopped state, the needle valve (44) retreats from the opening (42b) of the valve element (42) in conjunction with the movement of the valve element (35a) of the electromagnetic spill valve 30, thus forming a micro gap. When the high pressure fuel pump (1) is driven and the intake stroke is performed, the needle valve (44) obstructs the opening 42b of the valve element (42) in conjunction with the movement of the valve element (35a) of the electromagnetic spill valve 30, thus preventing the back-flow of fuel due to the existence of the micro gap.

摘要： A fuel injection pump 100 comprises a thermoelement CSD 47 for advancing injection timing in a cold temperature condition. The CSD 47 uses a piston 46 for opening and closing a sub port 42 formed in a plunger barrel 8. An electronic governor 2 is provided with a mechanism for decreasing an injected fuel quantity when an engine starts in a cold temperature condition. The mechanism shifts a rack position in a fuel-decrease direction in a cold temperature condition, and switches the rack position to a normal position in a normal temperature condition. A timing TR for shifting the rack position is set before or simultaneous to a timing TC for switch-off of the CSD 47.

摘要： A fuel supply system is incorporated into a diesel engine including a low-pressure fuel pump 2, a high-pressure fuel pump 3, a common rail 4, fuel injection valves 5 and a fuel return line 14. The fuel supply system reduces the discharge rate of the low-pressure fuel pump 2 supplying the fuel to the high-pressure fuel pump 3 when the diesel engine is in an idling state and the temperature of the fuel is below a lower fuel temperature threshold and when the diesel engine is in an idling state and the temperature of the fuel is above an upper fuel temperature threshold. The flow rate of the feed fuel discharged from the low-pressure fuel pump is reduced when an idling state or a specific state where the fuel is at a specific temperature. Thus the fuel line system of the fuel supply system can be built in a lightweight arrangement and the piping of the fuel line system can be simplified.

摘要： A method and system for controlling an internal combustion engine is provide. The engine has a fuel-supply device, a low-pressure circuit and a high-pressure pump, to which a control valve for a volumetric flow is allocated is provided. Said pump is coupled on the inlet side to the low-pressure circuit and transports fuel to a fuel accumulator. An estimated value of the drive torque of the high-pressure pump is determined in accordance with the fuel pressure in the fuel accumulator. A loss torque is determined in accordance with the estimated value for the drive torque of the high-pressure pump and additional loss-torque fractions, which are dependent on a motor speed and additional operating variables. A target torque is determined in accordance with the loss torque and an actuating signal for controlling an actuator of the internal combustion engine is generated from the target torque.
