Abstract: A cast-aluminum engine block for a compression-ignition internal combustion engine includes a plurality of cylinders that are disposed in an in-line arrangement. The engine block includes a top portion including a top deck and a bottom portion including a plurality of main bearings that are disposed to support journals of a crankshaft. An integrated flow channel is formed between the second end and the last cylinder and proximal to the top deck, and is a continuous channel that passes from the first side to the second side through the portion of the engine block between the second end and the last cylinder and proximal to the top deck. A coolant passageway is disposed in the engine block between the integrated flow channel and the last cylinder, and is oriented parallel to the elevation axis.

Abstract: A core assembly for a plate-and-fin heat exchanger includes a pair of core plates and a heat-absorbing member disposed within the passageway that secures the pair of core plates together. The heat-absorbing member defines a plurality of fins that each include one or more bending points, and each bending point creates two points of contact between a core plate and the heat-absorbing member.
