Zusammenfassung:This invention provides a method and apparatus for preheating combustion (intake) air of an internal combustion engine during extreme cold ambient temperatures. A valve arrangement is provided to alter the flow of coolant through a radiator and aftercooler. During conditions where intake air temperature is below a predetermined temperature a fluid control valve causes coolant to first flow through a jacket water portion of the engine and next through the aftercooler where the intake air is preheated.
