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 ...

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 ...

You've heard that pistons have rings, but have you ever wondered why there are three? Here's how piston rings work together to keep your engine running.

Human creativity, it seems, knows no bounds when it comes to inventing new ways to build a petroleum-based fire inside an enclosed metal space and then convert the resulting energy pulse into forward ...

A small company called Pinnacle Engines wants to radically change the internal combustion engine. Instead of a cylinder head, combustion pushes two cylinders away from each other in the same cylinder, ...

According to fleet executives as well as fleet maintenance managers, the death of the internal combustion engine may prove to be greatly exaggerated in spite of the excitement about electric ...

Through the history of internal combustion engines, there has been plenty of evolution, but few revolutions. Talk of radically different designs always leads to a single name – Wankel. The Wankel ...

To celebrate HOT ROD's 75th anniversary, we teamed up with CASTROL GTX to bring you some of the stories that exemplify the core of what HOT ROD is and reflect the brand's influence on America's car ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...

Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to satisfy monster power requirements or to hit a high level of performance within ...

At a time when heavy-duty internal combustion is frequently castigated in the shadow of zero-emission all-electric and fuel cell powertrains, a leading non-profit clean transportation group is ...
