In this video, you'll see the different types of engines and propulsion systems used for aircraft, my favorite ones: Turbojet ...

Researchers aim to meld the best attributes of both the power-dense two-stroke and the vastly cleaner four-stroke engines.

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?

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 ...

Diesel engines can technically run backwards, though there's very little (if any) practical applications for this, especially ...

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 ...

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.

As Ram touts a refreshed HEMI engine for 2026 and Dodge makes HEMIs stock for all 2026 Durangos, we dove into the history of ...
