Abstract
A vehicle engine cooling system includes a primary cooling circuit having a primary radiator and a coolant pump. A secondary cooling circuit includes a secondary radiator, an EGR cooler, and a liquid/air charge air pre-cooler receiving engine inlet air from a turbocharger compressor. The coolant pump circulates coolant through the EGR cooler, through the charge air pre-cooler, and through the primary and secondary radiators. A fan blows cooling air through the primary and secondary radiators. The secondary radiator is downstream of the primary radiator in the fan airflow. The cooling system also includes an air-to-air charge air cooler which receives engine inlet air from the liquid/air charge air pre-cooler. The air-to-air charge air cooler is upstream of the primary radiator with respect to flow of cooling air. The cooling system also includes an auxiliary engine fluid cooler which is located between the air-to-air charge air cooler and the primary radiator.
