摘要： A diesel engine has a fuel injection nozzle to which pressurized fuel is supplied from a pump. The nozzle has a pressure sensor detecting the fuel pressure and a lift sensor sensing a lift magnitude of a needle valve. An electronic control unit (ECU) computes a variation ratio of the fuel pressure value which is measured by the pressure sensor. The ECU computes a non-increasing point in an increasing part of variation ratio and judge the point to be a timing for starting the fuel injection of the nozzle. The EPU also computes the actual fuel injection amount in accordance with the fuel injection timing as well as the fuel pressure and the lift amount of the needle valve both at the various points. The EPU control the actual injection amount to be identical to a target fuel injection amount.

摘要： An air-fuel ratio control device of an internal combustion engine is provided. The control device includes a learning section, a correction section, and an inhibiting section. When an execution condition is met, the learning section learns, as a deviation amount learned value, a constant deviation amount between a correction amount and its reference value in different manners between a case in which the lift amount of the intake valve is in a first lift amount region used only when the execution condition is not met and a case in which the lift amount is in a second lift amount region used only when the execution condition is met. The learning section computes and stores the relationship between the deviation amount and the lift amount based on the deviation amount learned value. A correction section computes the deviation amount correction value from the stored relationship based on the lift amount, and corrects the fuel injection amount command value using the deviation amount correction value. When there is no record of completing learning of the deviation amount when the lift amount is in the first lift amount region, an inhibiting section inhibits the lift amount from being shifted from the first lift amount region to other lift amount region.

摘要： In air-fuel ratio feedback control, a rich skip amount is made larger than a lean skip amount by an offset amount OS such that a feedback control center is offset to the rich side. As a result, the amount of error from an erroneous detection by an O2 sensor is absorbed and deterioration of gas emissions in a multiple-injection mode is minimized.
