Abstract
A powertrain assembly includes an internal combustion engine, a boost mechanism and a fluid supply mechanism. The boost mechanism is in communication with an air source and the internal combustion engine. The fluid supply mechanism includes a first accumulator in communication with a pressurized fluid supply from the internal combustion engine and the boost mechanism. The accumulator receives pressurized fluid from the internal combustion engine during engine operation and provides the pressurized fluid to the boost mechanism during an engine off condition.
