An engine system includes a charge air cooler assembly that is configured to direct air to different parts of the engine system and to reduce overall void volume within the air intake system. The charge air cooler assembly includes a first stage air-to-air cooler arranged to direct a first charge air along a first direction from an inlet to an outlet of the first stage air-to-air cooler. The charge air cooler assembly also includes a second stage air-to-air cooler arranged to direct a second charge air along a second direction from an inlet to an outlet of the second stage air-to-air cooler that is different from the first direction. In some embodiments, the first stage air-to-air cooler and the second stage air-to-air cooler are each disposed in a parallel flow arrangement relative to an air driver of the engine system.

Internal combustion engine powered system, charge air cooler assembly, and method of cooling charge air

A genset has an enclosure in which a bulkhead separates the enclosure into a high pressure compartment and a low pressure compartment. A first fan is located in the high pressure compartment and draws ambient air into the high pressure compartment and pressurizes the high pressure compartment to a first pressure that is greater than ambient pressure. A radiator is located within the high pressure compartment such that the pressurized air in the high pressure compartment flows through the radiator and out of the high pressure compartment. A generator is located in the high pressure compartment and provides a gas flow path therethrough from the high pressure compartment to the low pressure compartment. An engine is located in the low pressure compartment and is coupled to the radiator for cooling and is coupled to the generator through the bulkhead to drive the generator.
