That fresh air is squeezed into a small pocket in the center of the cylinder as both pistons come together, where finally diesel fuel is directly injected, igniting the mixture and creating the power ...

The team at Garage 54 replace aluminum pistons inside of an engine with custom-made plastic pistons. The engine, surprisingly, runs for longer than it has any right to run. Garage 54 specializes in ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

Science isn’t fun if we don’t try to break or bend its limits, but sometimes this rebellion doesn’t work. For instance, we don’t make triangular wheels, perforated windshields, or lead pistons for ...

Unless you rebuilding an engine with little to no budget you're going to upgrade to aluminum forged pistons. Besides being stronger than cast pistons, the lighter aluminum cuts parasitic power loss.

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 ...

Cylinder wall scoring can be caused by a lack of oil or oil contamination. It can be prevented through careful maintenance ...

The Toyota 2GR-FKS is considered to be quite a reliable motor, but there may be trouble brewing within some older examples. Early 2GR-FKS V6 engines may suffer premature piston and cylinder wear. Main ...
