Scientists are exploring a surprisingly simple way to clean up diesel engines: adding tiny droplets of water to the fuel.

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 ...

Internal combustion engines have largely been eclipsed by advanced propulsion systems such as jet turbines, electric drives ...

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 ...

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 ...

There are a few different kinds of combustion engines out there. Most of them are fairly simple machines in theory, but decades of refinement and innovation have made modern engines into complex ...

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 ...
