    Abstract: An engine is configured to ignite an air-fuel mixture with an electric spark to ignite an air-fuel mixture. The engine includes: a cylinder head including a chamber partition wall having through holes and defining a main combustion chamber and a sub-combustion chamber; a fuel injector that injects fuel into the main combustion chamber; an air injector that injects air into the sub-combustion chamber; an ignition device causes an electric discharge between an ignition electrode and the chamber partition wall; and a control system that controls the fuel and air injectors, and the ignition device. At a compression stroke during a warm-up operation, the fuel is injected throughout a first period, and the air is injected throughout a second period at least partially overlapping the first period. At a power stroke during the warm-up operation, the electric discharge is caused after the fuel is injected.

  • Patent number: 11945431
    Abstract: A vehicle control apparatus includes a braking controller individually controlling braking forces of braking devices for left and right front and rear wheels, a side collision detector detecting a side collision against a vehicle, and a yaw behavior detector detecting yaw behavior of a vehicle body. If the yaw behavior detected after the side collision is such that a rear of the vehicle body shifts away from a collision side relative to a front thereof, the braking controller executes yaw amplification control to cause the braking device for the collision-side front wheel to generate a braking force larger than the remaining wheels. If the detected yaw behavior is such that the front shifts away from the collision side relative to the rear, the braking controller executes the yaw amplification control to cause the braking device for the collision-side rear wheel to generate a braking force larger than the remaining wheels.
