A primer on some of the more common specialty coatings and cylinder materials found in small displacement engines
This issue of Engine Professional is dedicated to specialty engines and niche marketing opportunities. Part of that market involves small displacement engines of all types and configurations. Past experience with these small bore engines has demonstrated a need to understand materials and coating in a way quite different from the run-of-the-mill gasoline engine. Motorcycle, water sport, snow mobile, off-road, stationary power plant and other specialty engines offer a machine shop many high profit opportunities. What has generally kept shops from exploiting these niche markets is a lack of knowledge on how to approach it, a clear understanding of what is required by way of equipment and an understanding of materials and coatings used in the manufacture of these engines.
We will attempt to give the reader a primer on some of the more common coatings and cylinder materials that can be found in these specialty engines as well as many automotive engine applications.
