Abstract
An internal combustion engine assembly including a solenoid pump having an armature and a solenoid winding encircling the armature such that the armature moves in response to current flow, including unwanted current variations, through the solenoid winding and a control circuit connected to the solenoid winding for detecting unwanted variable current flow in the solenoid winding and for controlling actual current flow in the solenoid winding in response to the detected unwanted variable current flow to thereby precisely control movement of the armature.
