Pre-chambered type spark plug with a flat bottom being aligned with a bottom surface of a cylinder head

摘要: The present spark plug is of the encapsulated design and facilitates life plug, enhances combustion process reduces emissions. position substantially within a cylinder head external chamber an engine close to cooling passage which heat transferred increases plug. configuration or makes manufacturing less costly by using one single orifice plurality orifices positioned at in preestablished manner. will reduce eliminate pre-ignition other detonation problems enabling timing be advanced further reducing
