There are many differences between diesel and gas engines, including some less obvious aspects of engine construction, such ...

Because internal combustion engines operate under such high pressures, it's tough to get their inner workings on camera. Usually the whole process is shrouded by thick metals to contain all of that ...

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.

Some agree that batteries are the clear winner in the race against hydrogen technologies, while others think the opposite. There's no such debate among internal combustion engine proponents. Almost ...

Automakers once bet big on bizarre ideas—from swirling airflows to variable compression—and the results were as fascinating as they were short-lived. Automotive engineers have invested countless ...

Patent documents reveal Ford is experimenting with hydrogen combustion engines. Not to be confused with fuel cell powertrains, the patent is for a conventional internal-combustion engine that would ...

It's been a long time since the automotive world has bothered with the mixing of oil and gas of the two-stroke combustion cycle — but soon, it may come time to rid ourselves of four-stroke engines, if ...
