In a combustion chamber, quench has nothing to do with the engine's appetite for fuel, but it's still important for making sure the engine runs efficiently.

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 ...

Optimisation of the intake system in internal combustion engines centres on enhancing the delivery of air (or air–fuel mixtures) to the combustion chamber in order to maximise power, reduce fuel ...

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 ...

You've heard the narrative: the era of internal combustion is on its way out, set to be replaced by cars with batteries and maybe, someday, hydrogen fuel cells. But the market isn’t moving in a ...

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 ...

Back when we posted about GM's efforts to send a vehicle back to the moon utilizing some of the same electric powertrain technology as the Hummer EV, a user on our Facebook page stated that this made ...

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 ...

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 ...

Automotive engineers have invested countless billions trying to improve upon the humble internal combustion engine, but not all those efforts have translated well. In fact, sometimes, things got weird ...

Reports of the death of the internal combustion engine have been exaggerated. Electric vehicles were once poised to diminish the ubiquity of traditional engines, but automakers are booking huge losses ...
