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： A fuel injector (1) in an internal combustion engine, wherein an intermediate chamber control valve (26) operated by the fuel pressure in a common rail (2) is arranged in a fuel flow passage (25) connecting a two-position switching type three-way valve (8) and an intermediate chamber (20) of a booster piston (17). When the fuel pressure in the common rail (2) is in a high pressure side fuel region, the booster piston (17) is operated by this intermediate chamber control valve (26), while when the fuel pressure in the common rail (2) is in a low pressure side fuel region, the operation of the booster piston (17) is stopped by this intermediate chamber control valve (26).

摘要： In controlling power supply time, a variation in the fuel injection quantity caused by a variation in the fuel injection rate at the in-cylinder pressure of the engine (detected or estimated value in the running state of the internal combustion engine) relative to the fuel injection rate at a reference in-cylinder pressure (under the condition of an injector characteristic measuring benchmark test), and in addition, a variation in the fuel injection start time is corrected. In the calculation of the variation in the fuel injection quantity, a fuel injection rate changing behavior model in which changing behavior of the fuel injection rate is modeled as a trapezoid is used to calculate the areas of Δq1 and Δq2. The variation in the fuel injection start time Δτd is calculated based on the rail pressure and the variation in the in-cylinder pressure. In this way, there is provided a technology for controlling the fuel injection quantity that changes with a change in the in-cylinder pressure with improved accuracy.

摘要： Injectors 2 are connected to a common rail 4 via respective dispensing conduits 3. A mixture of a liquid fuel fed from a liquid fuel tank 2 and an additional fluid fed from an additional fluid tank 9 is formed, and is fed to the common rail 4. The additional fluid contained in the mixture is turned to its supercritical state, and the mixture is injected from the injectors 2 to the engine. The inlets of the dispensing conduits 3 are positioned, with respect to the common rail 4, to open out into a liquid fuel layer which will be formed in the common rail 4 when a separation of the mixture occurs.
