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

But when done right, piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper selection for the intended ...

Your car's engine is truly a marvel of engineering, relying on a combination of extreme tolerances and pressures to produce power. Think about it — you're effectively creating hundreds of explosions ...

There are three things an engine needs in order to run: fuel, spark and a place to burn. This place, a combustion chamber, must be fairly gas-tight or the pressures developed during burning will be ...
