1. A power system comprising:
- an air-breathing, fuel-consuming, liquid cooled internal combustion (IC) engine providing a rotatory power output and producing products of combustion;
at least one turbocharger having a turbine for receiving the products of combustion from said IC engine and a compressor driven by said turbine for pressurizing air for delivery to said IC engine;
a primary heat exchanger in fluid flow connection to and interspersed between said compressor and said IC engine; and
a secondary heat exchanger in fluid flow connection between said compressor and said IC engine and interposed upstream of said primary heat exchanger, said secondary heat exchanger being an air-to-liquid heat exchanger and receiving liquid coolant from said IC engine.

Abstract
A work machine having an air-breathing, fuel-consuming, liquid-cooled internal combustion (IC) engine and a turbocharger receiving combustion products from the IC engine and a compressor for pressurizing air to the IC engine. A primary heat exchanger is in fluid flow connection between the compressor and the IC engine and a secondary heat exchanger is in fluid flow connection between the compressor and the IC engine and is upstream of the primary heat exchanger. The secondary heat exchanger is an air-to-liquid heat exchanger and receives liquid coolant from the IC engine.
