Definitions
- This invention involves a fuel composition that includes a combination of detergents and methods that utilize the fuel composition to operate and to control deposits in an internal combustion engine.
- Hydrocarbon fuels generally contain substances that tend to form deposits in the fuel delivery system of an internal combustion engine such as the fuel injectors in diesel engines and the intake valves in gasoline engines. These deposits, if allowed to build up, can significantly reduce engine performance in terms of power output, fuel economy and exhaust emissions. It is highly desirable to incorporate detergents into hydrocarbon fuels that are effective in controlling deposits by inhibiting their formation and facilitating their removal so that engine performance is maintained or improved.
