GM's upcoming 3.0L Duramax LM2 engine will utilize advanced cooling techniques known as Active Thermal Management, a first for a GM diesel engine.

The intricacies of heat transfer and cooling fluid flow within piston cooling galleries are central to optimising temperature regulation and mitigating thermal stresses.

This paper describes a method to effectively distribute the coolant flow in the engine coolant cavities and evenly remove the heat from various components using a novel technique of optimization based ...
