Abstract: A vehicle utilizes an internal combustion powertrain to propel front wheels and an Electric Rear Axle Drive (ERAD) to propel rear wheels. In some circumstances, a controller may need to limit motor torque in the ERAD to avoid overheating the motor, which reduces fuel efficiency. To reduce the likelihood of needing to limit motor torque, refrigerant from the vehicle air conditioning system is circulated through the motor housing. In response to commands from a controller, a valve routes the refrigerant either through the air conditioning system evaporator or through the motor housing.

Abstract: A high pressure fuel pump for use with an internal combustion engine and a method of operation of a high pressure fuel pump are disclosed. The high pressure fuel pump may include a supply chamber and a pump chamber separated by a passage in sealing arrangement with a disk. The disk may have one or more holes therethrough and be rotatable in order to place the holes in the disk in varying degrees of alignment with the passage to allow respective, varying amounts of fuel to flow through the passage.

Abstract: A method for operating a fuel pump is provided. The method may include decreasing a pump chamber pressure, passively opening a metering valve coupled to a pump chamber in response to the decreasing, and while the metering valve is open, generating a rotational output via a motor, transferring the rotational output into an actuation force applied to the metering valve via a metering valve actuation device, and inhibiting the metering valve from closing via sustaining application of the actuation force.
Abstract translation: 提供了一种操作燃料泵的方法。 该方法可以包括减小泵室压力，响应于减小而被动地打开耦合到泵室的计量阀，并且当计量阀打开时，通过电动机产生旋转输出，将旋转输出传递到致动力 通过计量阀致动装置施加到计量阀，并且通过维持施加驱动力来阻止计量阀关闭。
