Abstract: An auxiliary oil circuit for a heat-generating assembly having a main oil sump and a fluid pump for controlling oil flow from the sump includes a first fluid passage in communication with the pump. The circuit additionally includes a remote reservoir for receiving sump oil via the first passage and an orifice in the first passage for controlling an amount of sump oil transferred to the reservoir. The circuit additionally includes an active first valve in the first fluid passage for selectively opening and closing communication between the sump and the reservoir. The circuit also includes a second fluid passage in communication with the auxiliary reservoir for returning the oil from the reservoir to the sump. Furthermore, the circuit includes an active second valve arranged in the second passage for selectively opening and closing communication between the reservoir and the sump.

Abstract: The present disclosure provides an engine cooling system for controlling the temperature of an engine of a motor vehicle. The system includes an engine cooling circuit for circulating a coolant to transfer heat from the engine to an airflow. An electric water pump is configured to circulate the coolant through the circuit at a maximum electric pump flow rate, and a mechanical water pump is configured to circulate the coolant through the circuit at a maximum mechanical pump flow rate that is higher than the maximum electric pump flow rate. The circuit further includes a selector valve configured to fluidly connect one of the electric water pump and the mechanical water pump to the engine. An engine control module generates a valve signal for actuating the selector valve to fluidly connect one of the electric water pump and the mechanical water pump to the engine.
