摘要： A cooling apparatus for an internal combustion engine includes a pump, a radiator, a flow rate adjustment valve, a bypass passage, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a valve member biasing component that biases the valve member in a valve-closing direction in which the open degree decreases. The valve member rotates in a valve-opening direction in which the open degree increases when a pressure difference increases between positions upstream and downstream of the valve member in a flow direction of coolant in the circulation circuit and rotate in the valve-closing direction when the pressure difference decreases. The controller increases the pump discharge amount as a target radiator flow rate that is a target of an amount of coolant passing through the radiator increases.

摘要： A control device for an onboard engine is configured to control the oil discharge pressure of an oil pump and execute, when determining that there may be an abnormality in the control of the oil discharge pressure, a change process that increases the target discharge pressure to a value that is greater than that before it is determined that there may be an abnormality in the control. When a discharge pressure sensor value in a situation in which the discharge pressure is being controlled based on the target discharge pressure increased through execution of the change process does not become greater than or equal to a discharge pressure threshold, the control device sets an upper limit for the engine rotation speed and increases the upper limit as the discharge pressure sensor value increases.

摘要： A flow passage device includes a circulation flow passage, a swing valve provided in the circulation flow passage, an energizing part, and a lock mechanism including a lock pin. The lock pin is configured so as to hinder the swing valve from opening, and to allow the swing valve to open. The swing valve is configured so as to rotate from a first valve position to a second valve position. The lock mechanism is configured so as to set a locked state and to set an unlocked state. The lock pin is configured so as to protrude as being energized by pressure of the fluid on an upstream side of the swing valve, and to retract as being energized by pressure of the fluid on a downstream side of the swing valve.

摘要： A cooling apparatus includes a circulation circuit, a pump, a flow rate adjustment valve, and a controller. The flow rate adjustment valve includes a valve member that rotates to change an open degree of the flow rate adjustment valve and a stopper that moves between a restriction position and a retraction position. The controller is configured to execute, when maintaining the open degree of the flow rate adjustment, a preparatory process of moving the stopper to the restriction position after arranging the stopper at the retraction position and arranging the valve member further in the valve-closing direction than the stopper through control of the pump discharge amount.

摘要： A cooling control device includes a first heat exchanger to which a coolant of an internal combustion engine is supplied, a radiator to which the coolant of is supplied, a coolant pump supplying the coolant, a flow amount control valve controlling a flow amount of the coolant, and a control unit controlling the flow amount control valve. The control unit acquires a first amount of heat which is accumulated in the coolant, a second amount of heat which is accumulated in the coolant by a heat exchange with the first heat exchanger, and a third amount of heat for changing a temperature level of the coolant to a targeted temperature level. A targeted dissipation amount is set from the first, second and third amounts of heat, and an opening of the flow amount control valve is set by a feedforward control.
