Patent ID: 7198023

Claim:
A sequential injection lubrication system for a spherical rotary valve internal combustion engine operating on natural gas or alternative fuels, the sequential injection lubrication system comprising: a lubricant rail in communication with a lubricant reservoir, said rail in communication with a plurality of lubricant injectors, each of said plurality of lubricant injectors in communication with a cylinder of an internal combustion engine having spherical rotary valves and operating on natural gas or alternative fuels; an injection control unit mounted to said internal combustion engine, said injection control unit having a plurality of fixed contact points mounted therein, each of said fixed contact points corresponding to and in electrical communication means with one of said plurality of injectors, said injector control unit having a rotating plate juxtaposed said fixed contact point, said rotating plate having a conductive brush mounted thereto for sequential rotational contact with said fixed contact points; a control panel in communication with a source of electrical energy and in communication with said conductive brush, said control panel controlling the flow of energy to said conductive brush, and controlling the opening and closing of said plurality of injectors and the introduction of said lubricant into the respective cylinder of said internal combustion engine and the frequency of said opening and closing of said injectors.
