ABSTRACT:
A spark plug and fuel injector combination. The spark plug has a central channel that funnels fuel into the lower portion of the spark plug, where it is superheated. A solenoid system causes a needle valve to rise up to allow a measured quantity of fuel to be injected into a cylinder through a nozzle, where it vaporizes upon exiting the spark plug. A spring releases the needle valve to close the nozzle. The spark plug also has an ignition ring on the base. The ignition ring produces an encompassing spark, which produces complete combustion of the vaporized fuel. This produces more power and better fuel economy.
