  • Patent number: 11549460
    Abstract: There is provided a water cooled engine including a cylinder head with minimized thermal strain. A head water jacket includes an inter-exhaust-port-wall water channel between a first exhaust entrance port wall and a second exhaust entrance port wall. A cylinder head includes a cooling water injection passage provided at a bottom wall of the cylinder head. The cooling water injection passage is positioned on the exhaust end side, and includes a passage entrance provided on the exhaust end side, and a passage exit directed toward the inter-exhaust-port-wall water channel. An exhaust port wall includes a heat dissipation fin extending from a first exhaust entrance port wall toward an exhaust end. The space between the heat dissipation fin and a second exhaust entrance port wall forms a water channel entrance of the inter-exhaust-port-wall water channel.

  • Publication number: 20220094168
    Abstract: The power conversion system includes an inverter circuit. The inverter circuit performs a grid-connected operation and an independent operation. When performing the independent operation, the inverter circuit may output, via a terminal, AC power converted to a load disconnected from a power grid. When the inverter circuit performs the independent operation, a control unit controls, when operating in a first mode, the power conversion system in a first time range such that an AC voltage is applied to the terminal, and controls, when operating in a second mode, the power conversion system in a second time range different from the first time range. The second mode includes control of stopping an operation of having the AC voltage applied to the terminal.
