Abstract:
1. A method for reducing deposits in a combustion engine having a combustion chamber operable to combust fuel and air mixtures therein, and an intake manifold including an intake valve operable to introduce at least air into the chamber and an exhaust valve operable to release combustion products from the chamber, comprising: introducing an organomolybdenum source into the vapor phase within an engine from a liquid phase of a lubricating oil in a crankcase of an internal combustion engine, and delivering the organomolybdenum source from the vapor phase into the combustion chamber through an intake manifold including an intake valve in a manner effective to reduce the formation of deposits in the intake manifold, as compared to using the lubricating oil without the organomolybdenum source.
