Abstract
A method of operating an engine system includes compressing intake air, restricting exhaust flow from the engine via a flow restriction device, and supplying compressor air to a compressed air subsystem of the engine during restricting exhaust flow. Supplying of compressor air may occur by selectively actuating a pressure control device to fluidly connect an inlet of a compressed air subsystem with the compressor. An associated machine and engine system include a compressor, a flow restriction device, a compressed air subsystem and a pressure control device to selectively fluidly connect the compressed air subsystem with the compressor when the flow restriction device is in a relatively more closed configuration.
