摘要： An electronic control unit, in an idle operating state, detects a crankshaft rotation fluctuation in each cylinder using a crank angle sensor, and updates an individual correction value for a control value for each fuel injection valve as a first learned value such that a degree of deviation in the crankshaft rotation fluctuation among the cylinders reduces. The electronic control unit uses a fuel pressure sensor to detect a manner of a fuel pressure fluctuation with fuel injection by each fuel injection valve, and updates an individual correction value for a control value for each fuel injection valve as a second learned value based on a result of comparison between a detected temporal waveform and a basic temporal waveform. In an idle operating state, a learning rate of the second learned value is reduced until the first learned value converges for the first time as compared with after its convergence.

摘要： This apparatus is applied to an engine equipped with a fuel supply system that supplies pressure-increased fuel to a fuel injection valve, and performs the fuel injection from the injection valve in one combustion cycle by a multiple injection process that includes a pre-injection and a main injection that are executed with an interval therebetween. The apparatus calculates a deviation between a required value (one-dot chain line) and an actual value (solid line) regarding the end timing of the pre-injection, based on the manner of fluctuation of the fuel pressure in the fuel injection that is detected by a pressure sensor. A target main injection timing and a target pre-interval are individually set on the basis of the state of operation of the engine. Based on the deviation, the target main injection timing and the target pre-interval, the apparatus sets control target values regarding the execution period of the pre-injection.

摘要： A fuel injection amount control apparatus for an internal combustion engine includes an ECU that commands a learning-purpose injection when a first learning condition regarding operation state and a second learning condition regarding load connection state are satisfied, and calculates an injection performance value that corresponds to the actual injection amount based on the amount of change in rotation speed, and further determines whether a delay of the learning process is permitted based on whether the learning process, despite occurrence of the delay, can be completed before the injector performance reaches a permissible limit value, and forces, when the delay is not permitted, the load connection state to be a specific connection state so as to satisfy the second learning condition. When it is determined that the delay of the learning process is permitted, the delay is permitted until the two learning conditions are satisfied.

摘要： A device executes a power limiting process when the number of pressure sensors determined to be normal in a second determination process made by a second processing unit is smaller than or equal to one. When only one pressure sensor is determined to be normal through the second determination process, and when that pressure sensor and a pressure sensor connected to only a first processing unit are determined to be normal in a first determination process made by the first processing unit, a process associated with fuel injection based on a detected value of the pressure sensor determined to be normal in the second determination process is executed, and a degree of limiting engine power through the power limiting process is reduced as compared with when both the pressure sensors are determined to be abnormal in the first determination process.
