Abstract: The turbocharged exit air from a turbocharger flows through an intercooler, and then into an air intake manifold of a diesel engine. The intercooler exchanges heat with a liquid coolant in the intercooler when the coolant is cooler than the charge air, and substantially does not exchange heat with the liquid coolant in the intercooler when the coolant is warmer than the charge air. A controller located on the coolant tubing leading into the intercooler compares the temperature of the charge air to the temperature of the coolant, and at least partially stops the coolant from circulating by at least partially closing a valve in the coolant tubing when the charge air is cooler than the coolant.
