摘要： A high pressure pump has a fuel passage and a pump chamber. Fuel flows into the pump chamber through the fuel passage. The high pressure pump includes a valve member and a plunger. The valve member is movable along a movable axis in a substantially axial direction of the valve member for controlling an amount of fuel flowing into the pump chamber through the fuel passage. The plunger is movable substantially along a movable axis in a substantially axial direction of the plunger. The plunger is capable of pressurizing fuel in the pump chamber to discharge fuel in the pump chamber. The movable axis of the valve member is displaced from the movable axis of the plunger substantially in parallel with each other.

摘要： A delivery valve is connected to a discharge passage, through which fuel in a compression chamber is discharged. The delivery valve is screwed to a mount hole formed in the cylinder. A communication passage is formed in a body to extend through the sidewall between a screwed part in which the mount hole and the body are screwed to each other, and a gasket. A small clearance is formed between an inner peripheral surface of the mount hole and an outer peripheral surface of the body. The communication passage provides communication between a fuel passage downstream of a valve seat member and the clearance. The clearance communicates with the suction chamber through a return passage formed in the cylinder.

摘要： A high-pressure pump is formed with a secondary suction passage, which branches from a fuel suction passage and communicates with a pump chamber. Check valves for preventing a backflow of fuel are disposed respectively in the secondary suction passage and a discharge passage. An electromagnetic valve for regulating a fuel discharge quantity is disposed in the fuel suction passage. Normal control for controlling the fuel discharge quantity by controlling opening timing and closing timing of the electromagnetic valve with respect to reciprocating movement of a plunger is performed when an engine rotation speed is higher than a predetermined value during operation of an engine. Valve closing control for holding the electromagnetic valve at a closed state is performed when the engine rotation speed is equal to or lower than the predetermined value.

摘要： A fuel injection apparatus for a diesel engine has a fuel injection pump for feeding fuel under pressure and fuel injection nozzles provided in the engine to inject fuel fed from the injection pump. A pressure sensor for detecting fuel pressure is provided in a midway in a fuel line connecting the injection pump to the injection nozzles. An electronic control unit (ECU) computes the frequency of the fuel pressure based on a detected value from the pressure sensor immediately after fuel is injected from the injection nozzles. The ECU then computes a fuel bulk modulus based on the result of the computation of the frequency of the fuel pressure. Based on the computed bulk modulus, the ECU computes a fuel injection start and end time. Further, the ECU adjusts an instruction value for fuel injection control based on the result of the computation of injection start and end, and controls the injection pump based on the adjusted instruction value.
