Internal combustion engines have largely been eclipsed by advanced propulsion systems such as jet turbines, electric drives ...

We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

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.

Camshafts are one of the most confusing components in an internal combustion engine. What makes those lumpy bumpsticks even more confounding is the sheer number of grinds available, and then multiply ...

Both gasoline-burning engines and diesel engines produce power through a process of internal combustion. However, the latter are usually larger, louder, and often dirtier. While many people may not ...

Generally, combustion engines follow a standard principle of operation founded on the premise that the crankshaft spins clockwise (as seen from the driver’s seat). That’s how the powerplants are ...

Hydrogen has caused some memorable accidents throughout recent history, so what’s Porsche doing to make it less volatile?

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 ...
