The spark plug has a central electrode with an ignitor tip at one end thereof and surrounded by concentric fluid flow passages. Liquid atomizing orifice means interconnect the passages and the mixture therefrom flows into a passage surrounding the ignitor tip of the electrode. A gas and liquid mixture (preferably hydrogen with water) are proportioned in response to the quantity of one of the two dispensed.Field of SearchWater in chargePrecombustion chamber assembly inserted in spark plug hole Combination igniting means and injector Using multiple injectors or injections Having a particular relationship between injection and ignition characteristics (e.g., nozzle location, spray pattern, timing relative to igniter location, timing) Tubes and attachments Hoods and shields Heaters Water into cylinder Injecting diverse fuels or different states of same fuel Water plus heat into charge Gaseous fuel and air mixer Combined liquid and gaseous fuel | |
