Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

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 ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...

SAE Transactions, Vol. 23, PARTS I and II (1928), pp. 145-150 (6 pages) COMPROMISES are necessary in designing a piston, sacrificing the quality of least importance under the given conditions.

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?

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.

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 ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is ...

The earliest piston engines typically had only one cylinder, and at best, produced horsepower measured in single digits. But once you have a working engine, it’s a relatively short step to adding ...

Since Michigan has a stay-at-home order due to the coronavirus, I've been partaking in what I am now officially dubbing Wrenchfest 2020—an all-out repair assault on my various broken cars. Last ...
