Cars, for the most part with the exception being the rotary Mazda, are powered by what is called a 4 Stroke engine.

We will explain those in a minute. The 4 stroke cycle is how an explosion of gasoline and air can be smoothly transferred into useable power to hurl you down the track or take you to work.

The rings also help scrape lubricating oil off of the cylinder, or bores walls so it does not get burned up in the cylinder.
