  • Patent number: 10968796
    Abstract: The disclosure prevents oil separated from blow-by gas by using a breather chamber and discharged to a valve chamber from leaking to the outside from a breather chamber mounting surface between the breather chamber and the valve chamber. A breather chamber includes cylindrical drain passages communicating with a valve chamber, and tips of the drain passages exceed breather chamber mounting surfaces of a cylinder head and a head cover and protrude from opening parts toward a side of the valve chamber, so the oil separated from the blow-by gas in the breather chamber can be reliably discharged to the valve chamber and prevented from leaking to the outside from the breather chamber mounting surfaces.

  • Patent number: 10961964
    Abstract: A multi-injection process includes performing intake synchronized injection in which fuel is injected in synchronism with an open valve period of an intake valve, and an intake asynchronous injection in which fuel is injected at a more advanced timing than during intake synchronized injection. A single-injection process includes injecting a required injection amount of fuel by intake asynchronous injection. An operating process includes operating a port injection valve for injecting fuel into an intake passageway. A selection process includes selecting the single-injection process if the temperature of an intake system of an internal combustion engine is not lower than a prescribed temperature, and selecting the multi-injection process if the temperature of the intake system is less than the prescribed temperature.
