Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the pistons in the cylinders.

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?

If you are a motorhead, an unusual engine will immediately get your attention. Most vehicles today have either an inline or V-shaped configuration, so anything peculiar will immediately stick out. If ...

Just about every piston engine is defined by two basic measurements: bore and stroke. Bore is the diameter of the cylinder. Stroke is the distance the piston travels from bottom dead center to top ...
