摘要： A fuel injection device (fuel supply system) of a common rail type fuel injection system for an engine includes a pressure sensor disposed in a fuel inlet of an injector for measuring a fuel pressure at a position where the sensor is disposed and an ECU for sensing various kinds of pressure fluctuations associated with the injection including a pressure leak due to an injection operation of the injector and waving characteristics due to actual injection thereof based on sensor outputs from the pressure sensor. The ECU serially obtains the sensor outputs from the pressure sensor at intervals of 20 μsec.

摘要： Tooth portions are formed at unit angles on a rotor connected with a crankshaft of an internal combustion engine. A toothless portion is formed on the rotor by irregularly changing the regular arrangement of the tooth portions. A controller of the engine estimates times necessary for rotation of unit angles of an arbitrary angular range of 50° CA including the toothless portion and a pair of tooth portions adjacent to the toothless portion by using times necessary for rotation of unit angles of a different angular range of 50° CA distant from the arbitrary angular range by 180° CA. Thus, the controller can maintain high controllability of the engine even when there occurs a range where the time necessary for the rotation of the crankshaft is not sensed appropriately.

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： In an apparatus, an actual fuel spray characteristic obtaining unit obtains, based on an operation of a learning fuel injection instructing unit in a learning mode, an actual fuel spray characteristic of an injector relative to a variable of a target interval period within at least one section in a usable range therefor. A phase difference calculating unit calculates a phase difference between a reference fuel spray characteristic and the obtained actual fuel spray characteristic. A phase correcting unit shifts the reference fuel spray characteristic by the calculated phase difference such that the reference fuel spray characteristic is corrected to approach the obtained actual fuel spray characteristic.
