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.

Piston rings are small engine parts with a big job. They seal combustion pressure, control oil on the cylinder wall, help ...

When you think of a large engine, you probably think of a heavy-duty truck V8. But the engines that actually power our world ...

Of all the innovative and weird experiments bike manufacturers carried out in the '70s, this Honda engine experiment stands ...

Flat engines are horizontally-opposed piston engines, and this group includes Boxer engines, but not opposed-piston engines like the Cummins 14.3L Advanced Combat Engine (ACE) designed to power tanks.

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...

The effects of PCV failure are especially noticeable in turbocharged engines, where crankcase ventilation becomes critical ...
