Continental Motors now offers nickel silicon carbide coatings for all its cylinders across all product lines.
“We are excited to add this enhancement across our entire range of cylinder products,” said Emmanuel Davidson, head of global marketing. “We believe this new option will benefit those who do not get to use their aircraft as often as they would like or those that live or fly near the ocean.”
“When used infrequently, piston engines are more prone to internal corrosion than engines that are flown on a regular basis since the oil layer left following operation will slowly fade away with lack of operation,” the news release said. “Further, since aviation piston engines are vented, moisture can enter the engine, especially as a result of the natural daily variation in temperature.” The coating “creates a barrier inside the cylinder that protects the cylinder from corrosion while hardening the cylinder wall leading to improved wear performance.” (Learn more in “Tectonic shifts” from the October 2015 issue of AOPA Pilot.)
Continental also said in the release that “These cylinders are backed by an additional warranty extension covering the new cylinder barrels for abnormal internal wear and/or corrosion for 5 years.”
The coatings are used by cars and trucks as well as racing organizations.
