Abstract
The present disclosure relates to methods and fuel compositions for reducing cavitation-induced damage in common-rail injection engines operated at high fuel pressures. The fuel compositions include a gasoline-like fuel and one or more cavitation inhibitor additives.
Claims18
A method of reducing cavitation damage in a common-rail injection engine, the method comprising:
- providing a gasoline-like fuel composition at a pressure of about 350 to about 5,000 bar to a fuel injector and/or a high pressure pumping system of a common-rail injection engine and combusting the fuel composition in the engine;
- the gasoline-like fuel composition including a major amount of gasoline-like fuel and a minor amount of a cavitation additive including a quaternary ammonium compound.
