摘要： A fuel injection system for an internal combustion engine is provided. The fuel injection system comprises a primary fuel injector, a sensor, at least one secondary fuel injector and a controller. The primary fuel injector is configured to inject fuel into an ignition chamber of the internal combustion engine. The sensor is coupled to the primary fuel injector, wherein the sensor is configured to sense a fuel pressure of the fuel being injected by the primary fuel injector throughout each injection cycle of the primary fuel injector. The at least one secondary fuel injector is configured to inject fuel into a respective ignition chamber of the internal combustion engine. The controller is configured to receive data indicative of the fuel pressure value throughout each injection cycle. The controller is configured to determine a fuel quantity drift parameter over a plurality of fuel injection cycles based on the data indicative of the fuel pressure value. The controller is configured to adjust a fuel quantity delivered by the primary fuel injector and each secondary fuel injector based on the fuel quantity drift parameter.

摘要： A fuel injector for an internal combustion engine, comprising: an injection nozzle (12) with a body (16) in which a needle (14) is arranged; a control chamber (46) collaborating with a control valve driven by an actuator. A device for detecting the position of the needle comprises a contactor element (62) actuated by the upper part of the needle (42), the device being designed so that the contactor element is in contact, in the closed position, with terminal-forming element (64) of the position detection device, and so that the lifting of the needle causes a break in contact. The contactor element may be a spring, installed in the control chamber (46) and which is deformed radially in the closed position so as to touch an end of a rod and thus close the detection circuit.

摘要： A common rail type fuel injection system of an engine includes: a common rail (12) for accumulating and holding high-pressure fuel; a fuel pump (11) for pressure-feeding fuel to the common rail (12); and an injector (20) for injecting the high-pressure fuel accumulated and held in the common rail (12). A pressure sensor (20a) is disposed in a fuel suction port of the injector (20). An ECU (30) sequentially detects a fuel pressure varied when the injector (20) injects the fuel and sequentially detects a fuel pressure varied when the fuel pump (11) pressure-feeds the fuel. When the injector (20) injects the fuel, the ECU (30) computes injection pressure by the detection values of these pressures and computes injection characteristics by the injector (20) on the basis of the injection pressure.
