Want To Improve Engine Efficiency? Anti-Coking Coatings can help.

August 21 2015 Non-stick, Anti-fouling

Automotive and aerospace engine manufacturers strive to improve efficiency, but over time catalytic coking and carbon fouling become a major engine efficiency robber.  Fuel nozzles over time slowly build up enough carbon to cause reduced fuel flow or obstruct the fuel injection pattern in the combustion chamber; causing reduced fuel efficiency, sub-par performance, and increased maintenance.

SilcoTek® anti-coking coatings, like SilcoKlean®, act as an inert barrier, preventing carbon catalytic interaction with injector metals; significantly reducing carbon build-up on key engine surfaces.  How effective is SilcoKlean® in preventing fouling?  Studies show SilcoKlean can reduce catalytic coking formation by up to 8X.

Have a sticking issue?

Coking and fouling can be a complex problem to solve.  Is the carbon formation caused by catalytic interaction with the injector metal or is the fuel simply sticking to the injector surface?

SilcoTek® offers a variety of coating solutions that reduce coking or improve resistance to oil wetting and sticking on injector needle surfaces. 

Reduce surface wetting

Hexadecane contact angle testing demonstrates how a SilcoTek coated needle resists oil wetting and stiction by up to 3x compared to an uncoated needle.  Reduced wetting (increased oleophobicity) can help to reduce carbon build-up on surfaces.
