  • Patent number: 11293547
    Abstract: A rotation position detection device includes a change drum, a magnetic field generator, and a magnetic field detector. The magnetic field generator is fixed to the change drum and rotates along with the change drum to differentiate an ambient magnetic field.

  • Publication number: 20210156320
    Abstract: An internal-combustion engine includes a variable compression ratio mechanism for changing a mechanical compression ratio, and a variable valve timing mechanism for changing the valve timing of an intake valve. When acceleration is demanded, a target compression ratio is set to a lower compression ratio than the target value in a normal condition, and the valve timing is set to the advance angle side. Since the allowable combustion pressure decreases in a prescribed intermediate compression ratio region, if an actual compression ratio exists in the prescribed intermediate compression ratio region in the course of a compression ratio change accompanying acceleration, the variable compression ratio mechanism restricts the intake pressure by increasing a degree of opening of a wastegate valve or reducing a degree of opening of a throttle valve, for example.
