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.
