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

Almost all gasoline engines, whether they're efficient-yet-less-refined four-cylinders, high-horsepower V6s, or growly and torque-rich V8s, use much the same process to create power. The "Otto cycle" ...

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.

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 ...

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 ...

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 ...

With oil reserves projected to exhaust by 2040 and mounting climate concerns, the automotive industry faces an urgent need for alternative fuel sources. Companies like Toyota and Honda have championed ...

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 ...
