摘要： An internal combustion engine control device has a cylinder pressure sensor for sensing pressure in a combustion chamber and a fuel pressure sensor for sensing fuel pressure fluctuating in connection with fuel injection from an injector. The control device calculates a combustion characteristic of a cylinder (for example, an ignition delay or a combustion rate) based on both of a cylinder pressure sensing value and a fuel pressure sensing value. The control device corrects an EGR quantity, supercharging pressure, and injection start timing in accordance with the calculated combustion characteristic. Thus, the control device performs cooperative control of the injection start timing (an injection mode), the supercharging pressure and the EGR quantity (intake air conditions) in accordance with the combustion characteristic of the cylinder.

摘要： A fuel-injector-replacement device obtains a learning value of characteristic data of an injector while an engine is running. The learning value stored in an ECU is updated into the learning value. When the engine is stopped, the characteristic data stored in an INJ-EEPROM are updated into the characteristic data stored in the ECU. When the engine is started, it is determined whether the characteristic data stored in the ECU agrees with the characteristic data stored in the INJ-EEPROM. When these data do not agree with each other, it is determined that the fuel-injector is improperly replaced without updating the characteristic data stored in the ECU.

摘要： A pressure sensor is located in a fuel passage, which extends from a pressure-accumulation vessel to a nozzle hole of a fuel injection valve. The pressure sensor is located closer to a nozzle hole than the pressure-accumulation vessel for detecting pressure fluctuated by injection of fuel through the nozzle hole. An instruction signal output unit outputs an injection instruction signal so as to instruct an injection mode of fuel to the fuel injection valve. A defective injection determination unit determines whether a detected pressure of the fuel pressure sensor is fluctuated in a fluctuation mode in a range assumed from the injection instruction signal. The defective injection determination unit determines that a defective injection occurs when determining that the detected pressure is out of the fluctuation mode in the assumed range.

摘要： A common-rail fuel injection system is equipped with a common-rail, a fuel pump 11, and an injector. The fuel pump has a plurality of fuel pumping systems. A pressure sensor is provided at a fuel inlet of the injector. When the fuel pump supplies fuel to each of the fuel pumping systems, an ECU detects a variation in fuel pressure in a fuel passage between the fuel pump and the injector. Based on the detected fuel pressure variation, the ECU computes a pumping characteristic with respect to each of the fuel pumping systems.

摘要： A fuel injection controller includes an ECU controlling an operation of a fuel injector based on a characteristic data of the fuel injector, an EEPROM provided to the injector, and an EEPROM provided to the ECU. Identification information by which the fuel injector is individually identified is stored in both of the EEPROMs. It is determined whether the identification information stored in the injector-side EEPROM is identical to the identification information stored in the ECU-side EEPROM. Based on this determination result, it can be determined whether the injector and/or the ECU are exchanged to new one.

摘要： A fuel injection detecting device computes an actual fuel-injection-start timing based on a falling waveform of the fuel pressure detected by a fuel sensor during a period in which the fuel pressure decreases due to a fuel injection rate increase. The falling waveform is modeled by a modeling formula. A reference pressure is substituted into the modeling formula, whereby a timing is obtained as the fuel-injection-start timing.

摘要： During a short duration injection, a triangular geometry is drawn in terms of the injection rate with respect to time, while a trapezoidal geometry is drawn during a long duration injection. The ON timing of the drive pulse is determined to be at a valve opening pressure achieving time before the start point of formation in time of the geometry. An injection pulse duration is determined from “the valve opening pressure achieving time+a needle rise time−a valve closing pressure achieving time,” and then the OFF timing of the drive pulse is determined.
