摘要： An engine cooling device (100) includes: a water pump; a radiator (2); a first cooling water channel (8a) going through the radiator (2); a second cooling water channel (8b) not going through the radiator (2); a solenoid valve (6) provided in the second cooling water channel (8b); and a control unit (7). The control unit (7) moves, at a time of closing the solenoid valve (6), a valve body (62) in a valve closing direction while the cooling water is passing at a decreased flow rate so as to close the solenoid valve (6) to cut off passage of the cooling water in the second cooling water channel (8b).

摘要： In changing over each of liquid shutoff valves (26, 27) from an open-valve state to a closed-valve state, this device seats a valve body with the aid of an urging force of a spring by stopping the operation of a pump (17), changes over an energization state of a coil of at least one of the liquid shutoff valves (26, 27) which is changed over to the closed-valve state from a state where the coil is not energized to a state where the coil is energized, and then resumes the operation of the pump (17). Upon detecting the start of operation of the pump (17), a valve control unit (35b) causes a pump control unit (35a) to perform opening-closing force-feed control. In opening-closing force-feed control, an amount of the cooling liquid force-fed by the pump (17) is set to an amount within such a range that the valve body of at least one of the liquid shutoff valves (26, 27) whose coil is energized is not displaced in a valve-opening direction while the valve body of at least one of the liquid shutoff valves (26, 27) whose coil is not energized is displaced in the valve-opening direction.

摘要： A cooling device includes an inner passage, an outer passage, an engine-driven pump, an electromagnetic control valve, and a driving circuit that regulates current flowing through the electromagnetic control valve by activating and deactivating a switching element. A cooling controller for the cooling device includes a processing circuit configured to execute an operation process for operating, when the engine-driven pump is driven, the switching element by setting a duty cycle of an activation time to a switching cycle, which is a reciprocal of a switching frequency of the switching element, to be a larger value when a temperature of the internal combustion engine is low than when the temperature is high and a cycle varying process for setting a longer switching cycle when the temperature of the internal combustion engine is less than a preset temperature than when the temperature is greater than or equal to the preset temperature.

摘要： In the case where an intake valve has its phase in a first region between a most retarded angle and CA(1), the rotational speed of relative rotation between an output shaft of an electric motor and a sprocket is reduced at a reduction gear ratio R(1) to change the phase of the intake valve. In the case where the intake valve has its phase in a second region between CA(2) and a most advanced angle, the rotational speed of relative rotation is reduced at a reduction gear ratio R(2) to change the phase of the intake valve. As long as the rotational direction of relative rotation is the same, the phase of the intake valve is changed in the same direction for both of the first region between the most retarded angle and CA(1) and the second region between CA(2) and the most advanced angle.

摘要： A control apparatus for a cylinder injection type internal combustion engine (10) is disclosed, wherein the fuel injection mode of the engine (10) is switched between a compression stroke injection and an intake stroke injection. When the engine (10) is cold, the compression stroke injection is selected for the injection mode so that injected fuel collides with the top surface of a piston (14) and is directed toward the vicinity of a spark plug (23). The control apparatus comprises decrease correction means. When the fuel injection mode is switched to the intake stroke injection, the decrease correction means decreases the fuel injection amount during the execution of the intake stroke injection from when the fuel injection mode is switched until a predetermined period elapses. The control apparatus comprises determining means, wherein, based on the condition of the engine (10) when the compression stroke injection is selected for the fuel injection mode, the determining means estimates the amount of fuel adhered on the top surface of the piston (14) at a time when the fuel injection mode is switched to the intake stroke injection.

摘要： When both a position sensor (407) and a motor (408) are malfunction, an ECU (500) limits the engine rotation speed to such a speed range that the pressure inside a circulation route remains at or below a predetermined value even when the opening degree of a control valve (4) is a minimum opening degree. When the position sensor (407) is malfunction but the motor (408) is not malfunction, the ECU (500) relaxes the limits on the engine rotation speed, compared with when both the position sensor (407) and the motor (408) are malfunction, by driving the motor (408) to an end of a motion range thereof and increasing the opening degree of the control valve (4) to an opening degree larger than the minimum opening degree.
