Fuel-derived deposits on injectors and elsewhere in engines can severely impair engine performance. This paper reports on a laboratory test procedure developed to produce thin deposit films from oxidized fuel on steel. The deposit films were analyzed by using x-ray photoelectron spectroscopy (XPS or...
