ABSTRACT:
An internal combustion engine has intake and exhaust ducts, including an exhaust duct portion formed as an integral part of the engine along with the engine coolant jacket and passages, the exhaust duct portion being located in good thermal contact with the engine coolant flow passages, and flow diverting valves in the exhaust duct portion to direct exhaust gases to flow through the exhaust duct portion when the engine is cold in order to accelerate warm-up, the valves causing the duct to be bypassed under normal operating conditions.
