ABSTRACT:
Oil is burned controllably in an engine to reduce valve and valve guide wear and valve seat face recession, thus extending cylinder head and valve life. A nozzle discharges atomized oil into an intake manifold. The nozzle receives the oil from a pressurized source of oil. Used engine lubricating oil from the engine is preferably the source of oil, thus both disposing of used oil and allowing the lubricating oil to be maintained fresher. An atomizing fluid, such as air or natural gas, is fed to the nozzle for atomizing the oil. An air and fuel mixture conveys the atomized oil into combustion chambers where the oil is burned. The oil has an additive that leaves a finely dispersed ash residue in the combustion chambers when the oil is burned. Where a valve closes against a seat face in the cylinder head, the ash residue reduces valve wear and seat face recession, presumably because the ash residue provides a cushioning effect. Run time between overhauls for repair or replacement of cylinder heads and/or valves is extended.
