ABSTRACT:
A dual oil cooler arrangement for positioning in a tapered coolant flow cavity of a diesel engine block includes a pair of virtually identical oil coolers each of which are elongated and which are positioned in an end-to-end configuration extending substantially the entire length of the diesel engine block. The front oil cooler has a front oil inlet and a rear oil outlet. The rear oil cooler has a rear oil inlet and a forward oil outlet. A flow conduit network connects the oil inlets in a parallel flow pattern with a supply source of oil while the oil outlets are connected with an oil filter. The tapered coolant flow cavity in cooperation with the two oil coolers creates balanced and uniform coolant flow to each cylinder. There is a reduction in conduit bends and contraction and expansion points by this flow network. The two oil outlets are positioned near the midpoint of the engine block and this enables the cooled and filtered oil to be introduced into the main oil rifle at a more centralized location. The dual oil cooler design provides less pressure drop. The result is better balance and greater uniformity in the delivery of cooled lubricating oil to critical engine components.
