Abstract

AN INTERNAL COMBUSTION ENGINE WITH FUEL INJECTION INTO THE INTAKE MANIFOLD WHEREIN AN ELECTROMAGNETIC VALVE ADMITS ADDITIONAL FUEL INTO THE INTAKE MANIFOLD IN RESPONSE TO ACTUATION OF THE STARTER. THE VALVE CAN ADMIT FUEL CONTINUOUSLY OR INTERMITTENTLY, EITHER DURING THE TIME OF ACTUATION OF THE STARTER OR DURING THIS TIME AND FOR AN ADDITIONAL PREDETERMINED INTERVAL OF TIME FOLLOWING TERMINATION OF SUCH ACTUATION. THE COIL OF THE VALVE IS

ENERGIZED ON CLOSING OF THE STARTER SWITCH WHEREBY THE FUEL CAN FLOW THROUGH A PASSAGE OF PREDETERMINED VOLUME AND ISSUES FROM THE ORIFICE OF AN ATOMIZING NOZZLE WHICH IS INSTALLED IN THE INTAKE MANIFOLD.
