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: A turbocharger wastegate actuator arm includes a first section made from a rigid composite material, a second section made from a rigid composite material, and a third section made from a flexible polymeric material positioned between and interconnecting the first and second sections and adapted to allow angular deflection of the first section relative to the second section, wherein a longitudinal axis of the first section and a longitudinal axis of the second section define a first angle when the actuator arm is in the first position and the longitudinal axis of the first section and the longitudinal axis of the second section define a second angle when the actuator arm is in the second position, the first angle being greater than the second angle.
