摘要： A fuel injection system for an internal combustion engine is provided which calculates the quantity of fuel required to bring the pressure in a fuel accumulator into agreement with a target pressure and then control an operation of a high-pressure pump based on the required quantity. Even in the absence of a change in pressure in the accumulator, the system controls the high-pressure pump based on the required quantity. Specifically, the system calculates a feedback fuel quantity required to compensate for a difference between the required quantity and a quantity of the fuel actually supplied to the accumulator, in other words, leans such a quantity difference to correct the required quantity, thus resulting in an enhanced response of the system to control the high-pressure pump to a change in pressure in the accumulator.

摘要： A characteristics-detecting-portion analyzes a fuel injection condition based on a fuel pressure waveform which represents a variation in a detection value of the fuel pressure sensor and then detects the fuel-injection-characteristic value based on the analyzed fuel injection condition. The detected parameter is learned and stored in a memory in association with a fuel temperature detected by a fuel temperature sensor. A fuel-injection-rate model is established based on the learned detected parameters. A command-fuel-injection start time and a command-fuel-injection period are defined by use of the fuel-injection-rate model and the current fuel temperature.

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： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with at least one of a combustion parameter or a controlled variable arithmetic expression. The combustion parameter arithmetic expression defines combustion conditions of the engine needed to achieve required values of engine output-related values such as exhaust emissions. The controlled variable arithmetic expression defines how to operate actuators for an operation of the engine to meet desired combustion conditions of the engine. The use of the combustion parameter or controlled variable arithmetic expression achieves simultaneous agreement of the engine output-related values with required values without mutual interference between combustion parameters associated with the combustion conditions. The engine control apparatus also works to correct target values of fuel injection-related combustion parameters based on a response delay of an air-related combustion parameter, thereby ensuring the accuracy in achieving required values of the engine output-related values.

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.
