Abstract

To bring mixture near electrodes, the actual required poor fuel-air mixture to be burnt, is brought in the vicinity of the spark through a hollow channel inside the body of the spark plug, and through one or more channels pointing towards the spark. A container with one-way valve which opens at suction stroke of the particular cylinder(s) contains the externally produced poor fuel-air mixture. Supply of mixture is controlled from a pressurised container with non return valve, and stop valve and or control valve. A central and a protruding side electrode are incorporated.
