Gearheads might be aware of piston skirts, but their exact function isn't always clear to those outside engineering. Here's ...

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?

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

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 ...

While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates (a-KATE-ezz) Power engineers are betting that an old ...

Modern piston engines are incorporating advancements such as fuel injection, turbocharging, and electronic controls (like Lycoming's iE2 system). Weight reduction is a key focus; engines like the ...

Opposed-piston engine technology has been touted as a possible alternative to conventional engine designs for years. Now, opposed-piston engine developer Achates Power reports that its 10.6L ...

V-shaped engines like the V6 and V8 power lots of cars, but you probably never think about what, exactly, that V angle is.

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 ...
