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?

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 ...

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 ...

Friction is the enemy of speed. Whether it's rolling resistance or the wind flowing over the body at speed, racers work tirelessly to dispense it. The concept of friction may seem like an entirely ...

The piston rings on any engine have three main purposes - to ensure the combustion chamber’s tightness, to clean the cylinder and to leave a very thin layer of oil on its surface in order to reduce ...
