Abstract
An upper cylinder area lubrication system is disclosed that dispenses a small amount of lubricant to the upper cylinder area of an internal combustion engine at regular intervals for a metered period of time. Typically, the lubricant is dispensed for one second every thirty minutes. An electric pump is used to draw the lubricant from the reservoir and apply it, preferably through a mixing chamber in the gasoline line located just before the gasoline is applied to the firing chambers. The control of the pump is via a solid-state timing device that separately sets the alternate on periods and the off periods.
