  • Patent number: 11835013
    Abstract: The disclosure relates to a cylinder head for covering a combustion chamber of an internal combustion engine. The cylinder head comprises at least one material recess for heat isolation, which is formed in a main body of the cylinder head and is arranged between a fluid-guide channel and a cooling channel. The material recess can be produced e.g. directly during the shaping (e.g. casting or pressing) of the cylinder head and/or thereafter. For example, in the event that exhaust gas is guided through the fluid-guide channel, a significantly lower heat input occurs from the hot exhaust gas into the cooling fluid. In addition, the thermal decoupling via the material recess leads to the hot exhaust gas cooling to a lesser degree in the fluid-guide channel.

  • Patent number: 11807210
    Abstract: In a driven state phase, target input torque is limited to a first limit value, whereas in a backlash-elimination state phase, the target input torque is limited to a second limit value and target engine torque and torque of a motor-generator are controlled according to the target input torque. In the backlash-elimination state phase, the target input torque is limited to the second limit value that is suitable for mitigating rattling shock, so that rattling shock can be appropriately mitigated. Meanwhile, in the driven state phase, the target input torque is limited to the relatively high first limit value, so that an MG rotation speed can be quickly increased to eliminate a rotational difference, which enhances the responsiveness of driving power up to when required driving power is obtained after elimination of the backlash.
