    摘要： A variable valve timing control apparatus includes: a relative rotational phase adjusting mechanism capable of adjusting a relative rotational phase between a drive-side rotational member and a driven-side rotational member between the most advanced angle phase and the most retarded angle phase; and a lock mechanism capable of locking the relative rotational phase at an intermediate phase between the most advanced angle phase and the most retarded angle phase; a first pump operated by a driving force of an engine; and an electrically driven second pump operated as an electrically driven pump. Hydraulic fluid is supplied from at least one of the first pump and the second pump, and the second pump is capable of operating even if the first pump is inoperative when the engine is not running.

    摘要： A cooling system for an engine in the present invention includes a first coolant route for circulating coolant between a water jacket of an engine main body and a heater core, a second coolant route for circulating the coolant between a waste heat recovery unit and the heater core, a first water-temperature sensor provided on the first coolant route, and a second water-temperature sensor provided on the second coolant route. An engine control unit makes an engine stop determination based on the coolant temperatures detected by the first water-temperature sensor and the second water-temperature sensor and, in making the engine stop determination, selectively uses the coolant temperatures detected by the first water-temperature sensor and the second water-temperature sensor in dependence on whether a heater unit including the heater core is in an operation state or in an out-of-operation state.
