Abstract: A vehicle includes a chain tensioner that serves as an oil damper using oil supplied from an oil pump. The vehicle includes a controller that controls a traveling mode of the vehicle in a BEV mode or a non-BEV mode. When shifting the traveling mode from the BEV mode to the non-BEV mode, the controller executes a high-pressure process for controlling the oil pump such that a supply pressure of oil supplied to the chain tensioner becomes higher when a duration of the BEV mode is greater than or equal to a specified time than when the BEV mode duration is less than the specified time.

The vehicle includes a controller that controls a traveling mode of the vehicle in a BEV mode or a non-BEV mode. When shifting the traveling mode from the BEV mode to the non-BEV mode, the controller executes a high-pressure process for calculating a supply pressure of oil supplied to the chain tensioner that is higher when a duration of the BEV mode is greater than or equal to a specified time than when the BEV mode duration is less than the specified time.

Abstract: A water jacket coolant passage division member includes: a partition member that has a planar shape that conforms to a groove-like coolant passage provided to a cylinder block that is provided to an internal combustion engine; an inner-side rubber member that is provided to an inner side of the partition member, and comes in contact with a cylinder bore-side wall surface of the groove-like coolant passage; and an outer-side rubber member that is provided to an outer side of the partition member, and comes in contact with an outer wall surface of the groove-like coolant passage. An internal combustion engine in which a cylinder bore wall has a uniform temperature can be provided by utilizing the water jacket coolant passage division member.

Abstract: A protective structure for a fuel pump includes a protector including a connecting wall, a first protective wall, and a second protective wall. The first protective wall and the second protective wall are disposed outside the fuel pump assembled to an internal combustion engine. A standing surface of the second protective wall on a side opposite to a second base end surface in a standing direction of the second protective wall includes a curved surface that is concave on the second base end surface side and that becomes closer to the second base end surface side as the curved surface becomes farther from the first protective wall.

Abstract: A water jacket spacer is provided that ensures that a cylinder bore wall has a uniform temperature. When a contact member that comes in contact with the all surface of a groove-like coolant passage is provided to either or both of the inner wall side and the outer wall side of the water jacket spacer along the longitudinal direction of the water jacket spacer to divide the groove-like coolant passage into an upper part and a lower part, it is possible to separately control the flow rate of the coolant that flows through the upper passage of the groove-like coolant passage, and the flow rate of the coolant that flows through the lower passage of the groove-like coolant passage, and separately adjust the degree of cooling with respect to the upper part and the lower part of the cylinder bore wall.

Abstract: A temperature control device for an internal combustion engine includes a determining drive processor and an abnormality determining processor. The determining drive processor drives an electric pump when the difference between the water temperature and the ambient temperature is greater than or equal to a predetermined value while the electric pump is stopped. The abnormality determining processor determines that at least one of the water temperature sensor and the ambient temperature sensor is abnormal on a condition that the decrease amount of the water temperature. The determining drive processor includes a stopping processor, which stops driving of the electric pump when the cumulative amount of coolant discharged from the electric pump reaches the predetermined cumulative amount with driving of the electric pump. The predetermined cumulative amount is set according to the volume of the engine passage between the inlet of the engine passage and the water temperature sensor.

Abstract: A cooler apparatus includes: a coolant passageway; a water pump that circulates coolant in the coolant passageway; a thermostat that includes a heater that heats a temperature sensitive portion; and a controller. The controller is configured to drive the water pump and cause electric current to flow through the heater at a first energization amount when an operation in which the coolant is injected into the coolant passageway is started. The controller is also configured to stop electric current to flow through the heater if the water pump races when the electric current flows through the heater at the first energization amount.
