There are almost as many different engine models on the market today as there are applications. In many of these applications, engines must function in environments, which can be hazardous to optimum operation.

Although dirt can enter an engine from different sources, the most common path of entry is through the air intake system. Research shows that airborne dirt particles ranging in size from 10 to 100 microns cause the most engine damage. One micron equal 0.000039ths of an inch. The most harmful particles in this range are the silicates. Silicates are a major component of sand. At normal engine operating temperatures, silicates (sand) in the cylinders will crystallize to a diamond-like hardness.
