Engineers have a lot to think about when designing new engines, and one of the biggest considerations is the shape of the ...

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

It goes up, compresses a violent explosion, and goes down. A piston's job is easy enough to understand, but if you examine what it's required to do, you may be amazed it works at all. Think about ...

Many performance cars, including the supercharged Chevrolet Corvette Z06 and most Ferrari GT models, rely on forged pistons — instead of cast-aluminum pistons — for their additional strength. Forged ...

Picking up where we left off last month, here is the remainder of potent powerplants neatly packaged in a crate. Crate engines have, for some time, fascinated rodders, and why not-they provide ...

While they're not quite ready for production, the printed parts were lighter, ran cooler and unlocked more power than the standard forged pistons. Antuan started out in the automotive industry the old ...

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 ...

If you've been into cars for a while, you've probably swung a few engines over the fender that were assembled by someone else. That's cool, but it's probably about time to build one yourself. Overall, ...

Engine machining details reveal why some builders run pistons above the deck and how it affects compression and performance. #EngineBuilding #Racing ...

The modern HEMI V8 isn't a hemi engine in the true sense of the word, and it uses two spark plugs per cylinder instead of one ...
