Unless you drive a Wankel rotary, your combustion engine vehicle has pistons, and each of those pistons has three rings. Why ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

While there have been many unusual engine designs over the years, there haven't been many advancements involving the inner workings of the piston engine, except for higher-quality components, since ...

Regulating heat and pressure inside an engine is necessary for its healthy operation. Piston ring end gaps play a vital role in that, but they can be easily overlooked as a minor measurement. In ...

There's no need to sugarcoat what bad piston rings can do to your engine. Those rather thin cast-iron or steel rings may look small and irrelevant to untrained eyes, but they play a vital part in ...

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is a familiar pattern in all forms of motorsport. Engineers treat the rule ...

In theory, Wankel-style rotary internal combustion engines have many advantages: they ditch the cumbersome crankcase and piston design, replacing it with a simple, single-chamber design and a thick, ...

The bore scoring issues in Porsches can kill rod bearings, cause crankshaft and piston damage, and cracked cylinders.

An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

The Boss 302 was Ford's high-revving response to GM's DZ 302. Here's why this V8 punched above its weight class, all the way ...
