  • Patent number: 6990950
    Abstract: An electronic control unit (an ECU) of a fuel injection system performs a learning injection based on a learning injection quantity and obtains multiple influence values of an operating state of an engine generated through the learning injection. The ECU calculates a learning value for correcting the injection quantity in a normal operation based on the multiple influence values. The ECU determines whether the influence value obtained during the learning injection is within a predetermined range of the influence value. The ECU calculates a provisional learning injection quantity for bringing a subsequent influence value into the predetermined range if the influence value obtained in an early stage of the obtainment is out of the predetermined range. Then, the ECU calculates the other influence values by performing the other learning injections based on the provisional learning injection quantity.

  • Patent number: 6990952
    Abstract: An air amount control valve is connected to a sidewall of a throttle body in which a main air passage for supplying intake air into an internal combustion engine is formed. The air amount control valve has a bypass air passage bypassing the main passage and controls an amount of air flowing through the bypass air passage, thereby controlling an idling speed of the engine. The air amount control valve includes an aluminum alloy housing having a valve hole and a rotatable valve body having a valve surface facing a fringe wall of the valve hole. To prevent deposits from adhering to the fringe wall facing the valve surface, an anodic oxide film is formed to cover the fringe wall and further a fluororesin film is formed on the anodic oxide film.

  • Patent number: 6990953
    Abstract: A controller 21 controls an intake air flow rate via an electronic throttle 14 based on a feedback correction amount set so that a rotation speed (NE) of an internal combustion engine (11) during idle running gradually approaches a target value (tNE). When the deviation (?NE) between the rotation speed (NE) and the target value (tNE) becomes equal to or greater than a predetermined value (XNE), increase correction of the intake air flow rate is performed according to the deviation (?NE). When the deviation (?NE) falls below the predetermined value (XNE), a value corresponding to the increase correction amount at that time is added to the feedback correction amount, and subsequent increase correction amounts are set to zero, so the decreased engine rotation speed (NE) can be returned to the target value (tNE) with a rapid response, and future drops of the returned engine rotation speed (NE) are prevented.

  • Patent number: 6990955
    Abstract: There is provided a spark ignition engine having a low RON fuel tank to store a low RON fuel and a high RON fuel tank to store a high RON fuel, which can detect storage failure. It is judged that the two kinds of fuels are properly stored when differences between the base ignition timing and the practical ignition timing at different loads are identical. When the differences are not identical, for example, it is judged that the high RON fuel is stored both in the two fuel tanks when a difference between the proper mix fuel knocking-occur ignition timing and the practical ignition timing is decreased as the load is increased.

  • Patent number: 6990958
    Abstract: An electronic control unit (ECU) of an injection control system of an internal combustion engine determines that a load of a fuel pump is stabilized when a pressure-feeding operation delay elapses since a command pressure-feeding quantity outputted to the fuel pump reaches a certain pressure-feeding quantity necessary to maintain a target injection pressure. The ECU permits a single injection when a waiting period necessary to measure rotation speeds once for each cylinder before the single injection is performed elapses since the load of the fuel pump is stabilized. Thus, the single injection timing is determined based on the time point when the command pressure-feeding quantity is stabilized, the pressure-feeding operation delay, and the waiting period. Therefore, an injection quantity learning operation can be performed highly accurately in a short period.
