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 ...

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?

Cleaning up diesel emissions is one of the hurdles that must be cleared before diesel can become an accepted power mode in the United States, and a researcher in Maryland believes redesigned pistons ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

Shaking engines aren’t desirable, so we try to remove these forces. It’s easy to understand that as the piston comes to the top and stops, it sends an upward force, called a primary force.

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.

Achates Power’s cleaner, heavy-duty diesel engine it developed in a project funded by the California Air Resources Board and several partners has entered fleet service with Walmart in a Peterbilt 579 ...
