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

This disclosure relates a system for heating fuel supplied by a common rail fuel supply to an internal combustion engine. The system includes a high pressure fuel line, plural fuel injectors connected in series along the high pressure fuel line in the common rail, and a continuous low pressure passage including a heat exchanging portion in close proximity to the high pressure fuel line. A heated fluid source is operative to fluidly communicate with the continuous low pressure passage and circulate heated fluid to heat fuel present in the high pressure fuel line prior to, and during a cold start operation of the internal combustion engine. Other embodiments relate to a method of providing fuel to an internal combustion engine that includes sensing the temperature of fuel supplied to a fuel system and determining whether the sensed fuel temperature is greater than a predetermined value. The method includes circulating heated fluid in a continuous low pressure circuit to heat fuel present in a high pressure fuel line if the sensed fuel temperature is less than or equal to a predetermined value, and evacuating fluid for heating fuel from a portion of the continuous low pressure passage and fluidly connecting the evacuated portion of the continuous low pressure passage to a fuel leakage detection device if the sensed fuel temperature is greater than the predetermined value.
