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 ...

With all the recent emphasis on electric vehicles, we often overlook the technology that still powers most cars on the road today. The internal combustion engine (ICE) has been at the heart of the ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

The original concept of combustion engines as we understand them dates as far back as the late 1800s. And while they are more or less a solved science today, they definitely didn't start that way.

For most enthusiasts, the word “Hemi” belongs to Chrysler, yet Chevrolet quietly touched hemispherical combustion chamber ...

Power Up Your IC Engine Systems Knowledge at Michigan Tech. From heavy-duty trucks and agricultural machinery to shipping fleets, aviation, and power generation, internal combustion engines STILL ...

As the off-highway industry, including construction, navigates changes to emission regulations, the growing adoption of electrification, and the development of renewable fuel technology, manufacturers ...

Most aspects of a cylinder head are relatively straightforward and easily grasped. Valve size, deck thickness and combustion chamber volume are often topics of discussion and qualify the design's ...

Small, ultra-fast, primary and “afterburner” secondary combustion events promise to deliver brake thermal efficiency as high as 69 percent. A better mousetrap? Even now, as electrification seems ...

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 ...

Reports of the death of the internal combustion engine have been greatly exaggerated. In the wake of stalled consumer demand and stubbornly high costs, automakers around the world are furiously ...
