SPARK PLUGS
• Spark plugs designed for chain saw, brushcutter and lawn mower applications. • High quality European made. • Blister packaging for merchandiser.
Terminal pin Made of a steel wire resistant to vibrations. Its lower part is designed for connection with the seal, the upper part is used for the attachement of high voltage inlet.
Terminal nut All OREGON® spark plugs have locked terminal nuts to ensure efficient connection and resistance to vibration even in extreme conditions.
Insulator High content of aluminium oxide AL 2 O 3 ensures a high insulation resistance, good thermal conductivity and mechanical strength.
Ribs on insulator surface extend surface trajectory for eliminating any surface discharges.
Resistive seal • mechanical connection of insulator, terminal pin and centre electrode • electrical connection of terminal pin and centre electrode • gas tightness of the combustion area For spark plugs with radio interference elimination it provides suppression of electromagnetic radiation. There are two contact layers and one resistance layer.
Shell Features a high mechanical strength and surface protection from corrosion.
Internal sealing washer Ensures gas tightness of the combustion chamber and a perfect heat transfer from the combustion chamber to the shell.
Centre electrode Features high resistance to burn-off and optimum thermal conductivity.
Sealing washer Ensures gas tightness of the combustion chamber and a proper heat transfer from the spark plug to cylinder head.
Insulator tip Its shape facilitates regulation of heat removal from the combustion area.
Ground electrode Features high resistance to burn-off and optimum thermal conductivity.
