Abstract

An engine air intake system includes an engine air intake device and a plenum cooling compartment that is separate from the engine compartment by a baffle. A fan draws outside ambient air into the plenum cooling compartment and out of the plenum cooling area via a heat exchanger. The cooling compartment is designed such that a distance between the heat exchanger and the baffle provides a gap from which the engine air intake device removes ambient air as a source for engine air. An option is provide for the system to withdraw outside ambient air from an area external to the plenum cooling compartment in high debris environments.
