ABSTRACT:
An injector system adaptable for outputting a predetermined volume of lubricating oil from a diesel engine into an engine fuel system includes a piston slidably disposed in a body and cooperates with the body to define a first and second chamber in the body at opposite ends of the piston. A controller controls the movement of a valve to alternately connect the first and second chambers to a pressurized source of oil so that fluid filling one chamber moves the piston which will expel fluid from the other chamber. The chamber remains filled until the valve is actuated to connect the unfilled chamber to the pressure source which causes the chamber to fill with oil and expel the oil from the previously filled chamber.
