Abstract: An EGR valve includes a valve seat in a flow passage of a housing, a valve element seatable on the valve seat, a rotary shaft to open or close the valve element, a motor and a speed reducing mechanism, a return spring urging the valve element in a valve closing direction, and an opening-degree sensor to detect an opening degree of the valve element. An electronic control unit (ECU) diagnoses abnormality due to lodging of foreign matter between the valve seat and the valve element during full close. When driving the motor to urge the valve element in the valve closing direction during full close of the valve element, the ECU determines the EGR valve to be abnormal because of lodging of foreign matter if a difference between a value detected by the opening-degree sensor and a predetermined reference value is larger than a first determination value.

Abstract: A grille shutter device includes a grille shutter configured to change its opening degree and placed in a grille opening continuous with an engine room of a vehicle. An ECU controls a motor to control an opening degree of the grille shutter to regulate running air from the grille opening to an engine. The running air passing through the grille shutter flows to a lower part of the cylinder block. The ECU controls the motor to control the opening degree of the grille shutter according to a detected temperature of the lower part of the cylinder block by a temperature sensor. When judging that warm-up of the lower part of the cylinder block is not yet completed, the ECU controls the motor to close the grille shutter in order to block the running air flow from the grille opening to the lower part of the cylinder block

Abstract: An intake bypass passage is provided between an intake passage downstream of a compressor and the intake passage upstream of the compressor and provided with an ABV. The ABV is a diaphragm valve in which a housing is defined by a diaphragm to form a pressure chamber. A valve seat is provided in the intake bypass passage, and a valve element provided integrally with the diaphragm is arranged to seat on the valve seat. The valve element is urged by a spring in a direction to seat on the valve seat. A pressure passage communicated with a surge tank downstream of a throttle valve is connected to the pressure chamber. The valve element is formed with a communication hole communicating the intake passage downstream of the compressor with the pressure chamber.
