Abstract
An automotive fuel injector having a fluorine-coating amphorous hydronated carbon film coating to resist the formation of carbonaceous deposits thereon. The fluorine-coating amphorous hydronated carbon film is made in part form trifluoromethyltrimethylsilane. The coating helps the fuel injector resist coking or the growth of hard carbonaceous deposits. This reduction in coking and deposits improves the fuel economy and engine performance.
Claims6
A deposit-resistant internal combustion engine component, comprising:
- a coating on at least one surface of the engine component, said surface being susceptible to deposit formation;
- and said coating being a fluorine-containing amorphous hydrogenated carbon coating made in part from trifluoromethyltrimethylsilane whereby said coating prevents deposit formation on the engine component.
