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 ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

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 ...

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 ...

Engines fail for two basic reasons: flawed parts or improper build technique (or both). Building an engine is not for the faint of heart, yet it is something you can do yourself if you take your time ...

Drop cap initial letterLet's get one thing straight: The variable-valve-timing, direct-injection, turbo-wonderful powerplant in your new car is not cutting-edge. Despite the complexity of the modern ...

Ford once sketched a road where an engine's pistons never saw oil and engines ran hotter on purpose. In a late‑1980s patent application filed and granted in Europe, the company described an "uncooled ...
