    摘要: An electronic control unit detects a manner of fluctuation of a fuel pressure with injection of fuel by a fuel injection valve with the use of a fuel pressure sensor, and calculates a tendency of deviation of an actual fuel injection characteristic of the fuel injection valve with respect to a basic fuel injection characteristic on the basis of a result of comparison between a detected temporal waveform and a basic temporal waveform. The tendency of deviation is reflected at a predetermined reflection rate (R) at the time of updating a learned value (Gij) for compensating for an individual difference of the fuel injection valve. The predetermined reflection rate (R) is increased when an accumulated value (D) of a vehicle travel distance is shorter than a predetermined value (Dth) as compared with when the accumulated value (D) is longer than or equal to the predetermined value (Dth).

    摘要: A cetane number estimation apparatus injects fuel from a fuel injection valve in a diesel engine based on a target fuel injection amount, calculates an indicator of output torque of the diesel engine produced through fuel injection, and estimates the cetane number of the fuel using the calculated indicator. The cetane number estimation apparatus includes a pressure sensor for detecting fuel pressure varied by variation in actual fuel pressure in the fuel injection valve at the time of the fuel injection. The cetane number estimation apparatus also has a pressure correcting section that is adapted to calculate actual operating characteristics of the fuel injection valve based on a variation waveform of the detected fuel pressure and corrects the target fuel injection amount based on the difference between the calculated actual operating characteristics and prescribed reference operating characteristics.

    摘要: A fuel injection control apparatus of an internal combustion engine is disclosed. This apparatus is provided with a crank angle detector that includes a signal rotor having a number of tooth portions and a toothless portion. The crank angle detector outputs a first signal corresponding to each tooth portion and a second signal corresponding to the toothless portion. A control computer selectively carries out a first calculation process for calculating the timing of fuel injection using the first signal and a second calculation process for calculating the timing of fuel injection using the second signal. When carrying out the second calculation process, the control computer calculates the timing of fuel injection using the length of time gained by dividing the length of time gained through detection of the toothless portion by the number of tooth portions which can be aligned in the toothless portion.
