  • Patent number: 10414390
    Abstract: A control apparatus is applied to an internal combustion engine. The engine comprises a water pump, and an oil pump. The apparatus makes a second motor to drive the water pump drive the oil pump, if the first motor to drive the oil pump malfunctions. Consequently, if the first motor malfunctions, the oil pump can be driven by the second motor. Thus, the possibility of seizing of the sliding portions of the engine can be reduced. Further, if the first motor malfunctions, the friction in the engine can be reduced, since the oil pump is not driven by the crank shaft.

  • Publication number: 20140109856
    Abstract: A starter is disposed with an elastic body which generates slide resistance between the inner circumferential surface of a cylinder hole of a movable core and a first annular groove section of a flange section of a hook and the starter has an air damper function; and consequently, the effect of suppressing compression of a drive spring can be sufficiently obtained without reducing the suction speed of a plunger as much as possible and an engine can be rapidly started up.

  • Patent number: 8490593
    Abstract: The present invention is an installation of an emergency starting switching device and/or direct current boosted boost circuit device. When the power of the starting battery is insufficient, the electric energy of the power storage device battery is used to drive the starting motor in order to start the engine by operating the emergency starting switching device. And when the engine is started, the voltage of the ignition device or the fuel injection device is stepped up to strengthen its starting capability by means of a voltage boost by the direct current boosted boost circuit device.

  • Patent number: 8442717
    Abstract: In an ECU provided for idle-stop control, when a user start command is outputted from an ECU to start an engine in response to a manual start operation of a driver, transistors are turned on and a solenoid is operated to engage a pinion gear of a starter with a ring gear. After a delay period of a delay circuit, a transistor is turned on by an output of the delay circuit and an electromagnetic switch is turned on to energize a motor of the starter. A microcomputer measures an actual delay time from when the user start command is outputted to turn-on of the transistor and checks whether the measured time corresponds to a normal time of the delay time.
