摘要： A fuel injection valve (2) includes a first injection hole group (14), a second injection hole group (15), a control chamber (20), a first needle valve (12), and a second needle valve (13). The first needle valve (12) opens/closes an injection hole in the first injection hole group (14). The second needle valve (13) opens/closes an injection hole in the second injection hole group (15). Lifting of the first needle valve (12), and lifting of the second needle valve (13) are controlled by a pressure of fuel in the control chamber (20). An automatic valve (32) is further provided to change a flow rate at which the fuel flows into the control chamber (20), or a flow rate at which the fuel flows out from the control chamber (20), based on a common-rail pressure in a fuel supply source (1), when the needle valves (12, 13) are lifted. Thus, the fuel injection valve (2) injects fuel at the optimum fuel injection rate in various engine operating states.

摘要： In a fuel system of an internal combustion engine, a fuel pressure sensor is disposed on a high pressure fuel pipe connecting common rail and a fuel injection valve. An electronic control unit (ECU) of the engine calculates the magnitude P of the fuel pressure fluctuation from the fuel pressure detected by the pressure sensor when a pilot fuel injection is executed. The ECU calculates the actual amount Qpl of the pilot fuel injection from the magnitude P and pressure Pc in the high pressure fuel pipe based on the relationship between Qpl and P, Pc determined beforehand by experiment. The ECU further corrects the fuel injection period of the fuel injection valve in such a manner that the difference dQpli between the actual amount Qpl and a target amount Qplt of pilot fuel injection becomes within an allowable range. Thus, the fuel injection amount of the fuel injection valve always agrees with the target fuel injection amount even if a fuel injection characteristics have changed after long period of operating the engine.
摘要翻译： 在内燃机的燃料系统中，燃料压力传感器设置在连接共轨和燃料喷射阀的高压燃料管上。 发动机的电子控制单元（ECU）根据执行先导燃料喷射时由压力传感器检测出的燃料压力来计算燃料压力波动的大小P. 基于通过实验预先确定的Qpl和P，Pc之间的关系，ECU从高压燃料管中的大小P和压力Pc计算先导燃料喷射的实际量Qpl。 ECU进一步校正燃料喷射阀的燃料喷射期间，使得实际量Qpl和引燃燃料喷射的目标量Qplt之间的差dQpli变为允许范围。 因此，即使在长时间运转发动机后燃料喷射特性发生变化，燃料喷射阀的燃料喷射量总是与目标燃料喷射量一致。

摘要： An injected fuel pressure boosting device provided with a large diameter piston, a medium diameter piston, and a small diameter piston. A high pressure chamber filled at high pressure at all times is formed at the outer end of the medium diameter pistons, while a pressure boosting chamber is formed at the outer end of the small diameter piston. A pressure control chamber is formed on the end face of the large diameter piston on the small diameter piston side. When high pressure fuel is supplied to the pressure control chamber, the large diameter piston moves to the medium diameter piston side, that is, the pressure boosting preparation position. At this time, the leaked fuel outflow port is closed by the end face of the large diameter piston.

摘要： A pressure boosting unit (110) is provided in each fuel injection valve of an engine (1). A pressure of fuel to be supplied to the fuel injection valve from a common rail (3) is boosted as required. An ECU (20) causes low pressure injection to be performed with the pressure boosting unit 110 being in a non-operated state, and high pressure injection to be performed with the pressure boosting unit (110) being in an operated state, and the pressure of the fuel being maintained at a boosted pressure. Based on the result, the ECU (20) corrects a fuel injection period of the fuel injection valve. Also, after the correction of the fuel injection period is completed, fuel injection is performed before the pressure of the fuel reaches the boosted pressure after the pressure boosting unit starts to be operated. Based on the result, operation starting timing of the pressure boosting unit is adjusted.

摘要： A first valve element (32) and second valve element (34) are arranged in a pressure switching chamber (30) of a three-way valve (8). When switching a destination of a fuel flow passage (15) from a high pressure fuel feed passage (5a) to a low pressure fuel return passage (26a), the state where the first valve element (32) is open and the second valve element (34) is closed is switched through a state where the first valve element (32) and second valve element (34) are both closed to a state where the first valve element (32) is closed and the second valve element (34) is open. Fuel pressure of a pressure control port (55) sealed by a sliding seal face (53) formed at an outer circumference of the second valve element (34) is used to control an opening timing of a needle valve (9).
