Abstract

New concept spark plug was developed to study its influence on the combustion characteristics of SI engine. It has pre-ignition chamber in the lower end of spark plug and flame hole. Fresh mixture gas can be got in pre-ignition chamber of spark plug without any fuel supply system. This spark plug was tested to a commercial engine. Fuel consumption rate, emission gas and MBT timing were measured in the engine dynamometer varying the flame hole number, hole position, hole size of the pre-ignition chamber of the spark plug. New concept spark plug induces fast burn in combustion than comparing with the conventional spark plug. MBT timing was retarded about 3~5˚ crank angle. The flame hole number, hole direction and volume of pre-ignition chamber were found to influence emission gases.
