Effective management of the ratio between air and fuel in internal combustion engines underpins both performance optimisation and emissions reduction. The air–fuel ratio (AFR) determines combustion ...

Combustion efficiency in internal combustion engines refers to the proportion of chemical energy in the fuel that is converted into useful mechanical work. Attaining high combustion efficiency is ...

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 ...

Converting the ignition of a fuel-air mixture into usable mechanical energy lies at the core of a dizzying number of internal combustion engines developed over the course of more than century.

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 was a time, not long ago, when we all believed there would soon be a moment when internal combustion engines would be completely replaced by electric drives of one nature or another. In the ...

Researchers from the Southwest Research Institute (SwRI) have successfully developed an optimized spark-ignited hydrogen ...

As the United States marks its 250th anniversary, WTOP presents “250 Years of America,” a multipart series examining the innovations, breakthroughs and pivotal moments that have shaped the nation ...

It feels like just a few years ago, V8 engines were destined for an early extinction. But in the face of disappearing EV incentives and changing demands, more and more automakers, like GM, are ...
