Abstract
A lubricating system for two-cycle crankcase compression internal combustion engines that provides adequate lubrication under all running conditions. The speed of the engine is sensed and provides a control signal to a mapping device which supplies the amount of lubricant between the maximum and minimum anticipated loads at that speed.
Claims7
In a lubricating system for a two-cycle internal combustion engine operating over a range of speed and load conditions wherein the lubricant demands of the engine at a certain one of such conditions range from a maximum amount at the maximum anticipated of the other conditions and a minimum amount at the minimum anticipated other condition, said system comprising variable output lubricant delivery means for delivering lubricant to the engine, the improvement comprising means for sensing the one condition and control means for controlling the amount of output of said variable output lubricant delivery means, said control means providing a predetermined amount of lubricant between the minimum and maximum amounts in response to the sensed one condition.
A method of lubricating a two-cycle internal combustion engine operating over a range of speed and load conditions wherein the lubricant demands of the engine at a certain one of the conditions range from a minimum amount at the minimum anticipated of the other conditions and a maximum amount at the maximum anticipated other condition comprising the steps of sensing one of the conditions and providing an amount of lubricant between the minimum and maximum anticipated other condition.
