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 ...

V-shaped engines like the V6 and V8 power lots of cars, but you probably never think about what, exactly, that V angle is. That's okay. Automotive engineers do.

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...

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 ...

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 ...

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 ...

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 ...

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is ...

Pistons play the ultimate role in an engine, but despite that, it's still hard to fully wrap your head around all the forces involved. There are plenty of moving parts in an internal combustion engine ...

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 ...

No experienced engine builder would intentionally bolt a cylinder head to an engine block without installing a gasket between the block and cylinder head. The gasket seals the block-deck surface to ...

Engine knocking can be an annoying issue to deal with, and it can even cause damage to your car. Here's why it might happen, ...
