Mahle has been granted a patent for a heat exchanger designed for internal combustion engines. The invention features a dual fluid channel system, reinforced S-shaped edge tabs, and a frame part with ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

The engine works by taking heat from the hot reservoir, converting some of it into useful work, and rejecting the remaining heat to the cold reservoir. The thermodynamic cycle followed by the engine ...
