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, ...

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 ...

When we here in the modern age think of an “engine,” we are usually thinking of a four-stroke, four-cylinder, gasoline-fed, internal-combustion engine with the valves on the top. But why must that be ...

From a gearhead's viewpoint—take that back, anybody's informed perspective—there's one guy who stands out as a catalyst in the art of automotive as we know it. Not talking about the caveman who ...

Conventional wisdom suggests that our faithful internal combustion (IC) engines are heading the way of the buggy whip. The lithium-ion battery has arrived, emissions standards are tightening, and ...

At the heart of an internal combustion engine lies a series of cylinders, cylindrical chambers that house the fiery combustion process. These cylinders, arranged in various configurations such as ...

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 ...

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 ...

YouTuber Integzaa’s latest video gives us a neat look inside the combustion chamber of a four-stroke engine, using a transparent cylinder to show us how the piston moves within it to create internal ...
