Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

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?

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 ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

The piston skirt and pin account for about 17 percent of the frictional loss in a combustion engine as they are the most difficult to keep lubricated and have the largest contact surfaces. OE ...

Pistons are an engine-building element we like to brag about, but you won't catch many of us boasting about having cast pistons. Cast pistons are for wimps. Many of us like to talk up hypereutectic ...
