Patent number: 7902733Abstract: This invention is an improvement to the internal combustion engine spark plug used to ignite the fuel air mixture in the engine combustion chamber. All spark plugs manufactured today produce one ignition spark for each high voltage electrical discharge of the ignition coil regardless of the number of spark plug electrodes used in the manufacture of the spark plug. This invention uses an intermediate electrically neutral electrode placed between the spark plug center electrode and the ground strap electrode creating two separate spark air gaps. For each single high voltage electrical discharge of the ignition coil, a spark will occur between the center electrode and the intermediate electrode and another distinct and separate spark will occur between the intermediate electrode and the ground strap electrode. Because the two ignition sparks are electrically in series, both will have the same electrical energy.Type: GrantFiled: October 16, 2007Date of Patent: March 8, 2011Inventor: Thad Whitfield Posey
