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.

1. A method for regulating the cooling of a turbocharged engine's intake air wherein said engine has a heat exchanger for transferring heat between a coolant and said turbocharged intake air from a turbocharger comprising the step of restricting but not stopping said coolant to exchange heat with a charge air from said turbocharger when said coolant is hotter than said charge air.2. The method for regulating the cooling of a turbocharged engine's intake air, according to claim 1, including the additional step of determining if the temperature of a coolant for cooling said turbocharged engine air is greater than the temperature of said charge air.3. The method for regulating the cooling of a turbocharged engine's intake air, according to claim 2, including the additional step of sensing the temperature of said charge air entering into said heat exchanger located in an intake air duct, and said coolant entering into said heat exchanger.4. The method for regulating the cooling of a turbocharged engine's intake air, according to claim 3, including the additional steps of:a) placing a first temperature sensing device in an engine's intake air duct upstream of said heat exchanger; and b) placing a second temperature sensing device in a tube holding said coolant, said tube being proximate and upstream of said heat exchanger. 5. The method for regulating the cooling of a turbocharged engine's intake air, according to claim 1, wherein said step of restricting but not stopping said coolant to exchange heat with a charge air from said turbocharger when said coolant is hotter than said charge air comprises the step of partially closing a valve in a coolant supply line.6.
