ABSTRACT:
Intake air heating and exhaust cooling is provided by a double wall exhaust system serving as an exhaust-to-air heat exchanger, sourcing hot air to the intake manifold for intake stroke pumping benefit and cooling the exhaust system during high load operation by routing excess boost air through an interstitial space of the double wall.
