Abstract: A heat transfer apparatus includes: an evaporating portion that evaporates a working medium by heat of an exhaust gas from an internal combustion engine; a condensing portion that condenses the working medium having been evaporated; a circulation path portion that causes the working medium to circulate between the evaporating portion and the condensing portion; a heat storage member that is provided within the evaporating portion; and a supplying and collecting portion that supplies the working medium to the evaporating portion when the internal combustion engine starts, and that collects the working medium having been condensed when the internal combustion engine stops such that the working medium having been condensed does not contact with the heat storage member.

Abstract: A cooling device includes: an evaporator cooling a cooling object by evaporating a heat medium in a liquid phase by a heat exchange between the cooling object and the heat medium; a condenser, disposed above the evaporator, radiating a heat of the heat medium to an external fluid by condensing the heat medium in a gas phase by a heat exchange between the heat medium and the external fluid; a gas-phase passage for guiding the gas-phase heat medium from the evaporator to the condenser; and a liquid-phase passage for guiding the liquid-phase heat medium from the condenser to the evaporator. Further, the gas-phase passage includes a rising portion on one side of the cooling device in a predetermined direction orthogonal to a vertical direction and at least a part of the rising portion rises above surroundings.

Abstract: A control device for controlling an internal combustion engine equipped with an engine body, a variable compression ratio mechanism A configured to be able to change a mechanical compression ratio of the engine body, and an intake system configured to be able to make exhaust discharged from combustion chambers of the engine body be recirculated to an intake passage of the engine body. The control device is provided with a compression ratio control part controlling the variable compression ratio mechanism A so that the mechanical compression ratio becomes the target compression ratio. The compression ratio control part sets the target compression ratio at a lower value when exhaust is being recirculated at a predetermined operating region at an engine low load side than when exhaust is not being recirculated.

Abstract: A control device for an internal combustion engine includes a knock control system, a cooling system, and an electronic control unit. The knock control system is configured to ignite a spark plug an ignition crank angle obtained by retarding the ignition crank angle in response to an occurrence of the knocking. The electronic control unit is configured to supply a command value corresponding to a target value of a cooling parameter to the cooling system such that the cooling system performs cooling of the internal combustion engine according to the command value. The electronic control unit is configured to correct the command value based on a KCS learned value such that as the KCS learned value increases, a correction amount for correcting the command value increases in correction amount in a direction in which a cooling capacity of the cooling system increases.
