摘要： In an apparatus, a shift quantity calculating unit tentatively shifts a reference fuel spray characteristic to an obtained actual fuel spray characteristic in a phase direction and in a magnitude offset direction while monitoring a distance between the reference fuel spray characteristic and the obtained actual fuel spray characteristic therebetween. The shift quantity calculating unit calculates a shift quantity between the reference fuel spray characteristic and the obtained actual fuel spray characteristic in the phase direction when the monitored distance is minimized. A phase correcting unit shifts the reference fuel spray characteristic by the calculated shift quantity in the phase direction to thereby correct the reference fuel spray characteristic.

摘要： A fuel injection system designed to execute a learning operation to spray fuel through fuel injectors at each of given pressures of the fuel to determine the quantity of fuel sprayed actually from each of the fuel injectors (i.e., an actual injection quantity) into an internal combustion engine. The system calculates a deviation of each of the actual injection quantities from a target quantity to determine an injection correction value required to eliminate such a deviation. The system determines whether each of the injection correction values has an error or not and analyzes the mode in which the errors appear at the injection correction values to specify types of malfunction occurring in the system. The system relearns ones of the injection correction values as determined to have the errors.

摘要： A fuel injection system designed to determine a correction value for correcting the quantity of fuel sprayed from a fuel injector into an internal combustion engine. The fuel injection system instructs the fuel injector to inject the fuel into the engine a plurality of times cyclically to learn an injection characteristic unique to the fuel injector and changes an injection duration for which the fuel is to be sprayed in each of injection events to disperse the injection durations evenly around a target injection quantity, thereby enabling the correction value to be determined in a decreased number of injections of fuel for a decreased amount of time.

摘要： A fuel injection characteristic detection apparatus is applied to a fuel feed system. The fuel feed system is configured to inject fuel into one of a cylinder, an intake passage, and an exhaust passage of an internal combustion engine by using a fuel injection valve. The fuel injection characteristic detection apparatus includes fuel pressure obtaining unit for successively obtaining pressure of fuel supplied to the fuel injection valve. The fuel injection characteristic detection apparatus further includes pulsation pattern storing unit for associating a pulsation pattern of fuel pressure, which accompanies an injection operation of the fuel injection valve, with at least a fuel injection mode and a fuel pressure level at a present time point and for storing the associated pulsation pattern in a storage medium.
