摘要： A switching mechanism switches the pressure stage of oil, which is fed from an oil pan to the individual parts of an internal combustion engine, between two stages, which are a low-pressure stage and a high-pressure stage. An electronic control device controls the action of the switching mechanism. The electronic control device determines that the liquid level of the oil is abnormal on the basis of the fact that the liquid level of the oil, which is detected by a liquid level sensor, in the oil pan becomes lower than a predetermined value. If the pressure stage of the oil is set at the low-pressure stage through the switching mechanism, the predetermined value is set at a higher value than that when the pressure stage is set at the high-pressure stage.

摘要： An electromagnetic PCV valve includes a valve seat, a valve element, a step motor for moving the valve element, and a housing that houses the valve seat, the valve element, and the step motor. When the valve element is moved by the step motor, a size (an opening degree) of a blow-by gas passage defined between the valve seat and the valve element is changed. The step motor is configured to selectively receive energization for moving the valve element and energization for holding the valve element in a fixed position. A heating apparatus of the PCV valve 1 includes a cover member and an output shaft that conducts heat generated in the step motor by energization to the valve element and the valve seat, and an electronic control unit (ECU) for conducting energization of the step motor to hold the valve element in the fixed position.
