Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

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 ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...

In a conventional application, there are three rings per piston. The top ring is called the compression ring. Its purpose is to seal the combustion gas pressure, transfer heat from the piston to the ...

Presumably that you want to replace the worn out piston rings of a Toyota VVTi engine, you’ll need to know how to correctly put the new ones in place. The hardest part is to reach the piston rings ...

Gamblers are a different breed. There’s a point where they seem to know when a bluff has gone too far, when it’s time to fold their hand and live to fight another day. The art of building racing and ...

Piston rings are the seals in your cylinders, giving you better compression and power, but what happens if they wear or break? And how can you spot the signs?
