  • Patent number: 10578060
    Abstract: A preset compression ratio of a gasket is set to be larger at a center segment than at fixation segments. In order to set the preset compression ratio in the above-described manner, a depth of a center-segment-side bottom surface of a cover is set to be smaller than a depth of each fixation-segment-side bottom surface at the cover. In this way, even when a phenomenon, which causes a reduction of the compression ratio of the center segment of the gasket relative to the compression ratio of the fixation segments, occurs, it is possible to limit the reduction of the compression ratio of the center segment to a value that is lower than the compression ratio of the fixation segment.

  • Patent number: 10514015
    Abstract: A control device of an internal combustion engine is provided. In the case where a switch request for switching from all-cylinder operation to partial-cylinder operation is made, before a switch from the all-cylinder operation to the partial-cylinder operation is executed, an intake air amount increase control increasing an intake air flow rate of an engine by increasing an opening degree of a throttle valve is performed, an ignition timing retardation control retarding an ignition timing is performed, and based on a retardation limit value of the ignition timing at a time point when the switch request is made, a start timing of the intake air amount increase control is changed. As a retardable amount being a difference between an initial ignition timing and the retardation limit value decreases, the start timing of the intake air amount increase control is delayed further.
