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 ...

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.

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 ...

In case you missed it, the automotive industry has been on a steady trajectory of internal combustion engine (ICE) downsizing for years. Battery-powered electric vehicles may capture most 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.

Heat transfer in internal combustion engines governs both performance and durability by controlling temperatures within the combustion chamber, cylinder walls, piston crown and cylinder head.

The rise to power of electrified powertrains had some believe, for a short while, that internal combustion engines (ICE) were done. To some extent, meaning the medium-term evolution of the automotive ...

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 ...
