Description
– A metal, colorful zinc automotive and motorcycle spark plug is a component designed to ignite the air-fuel mixture in an engine, creating combustion and generating power.
– These spark plugs, available in various colors, utilize a zinc coating for corrosion resistance and aesthetic appeal.
– They feature a central electrode and a ground electrode, separated by an insulator, with a metal shell that provides a ground connection and helps dissipate heat.
Key Components:
Central Electrode:
This is the electrode where the high voltage spark originates.
Ground Electrode:
This electrode provides the return path for the electrical current, completing the circuit and creating the spark.
Insulator:
This component insulates the central electrode and prevents electrical leakage, ensuring the spark occurs only at the tip.
Metal Shell (or Housing):
This part provides a secure connection to the cylinder head for heat dissipation and acts as the ground for the spark.
Zinc Coating:
The zinc coating provides corrosion resistance and can be used to create various colors for aesthetic purposes.
Resistor:
A resistor inside the spark plug helps suppress electromagnetic interference, ensuring the proper functioning of the vehicle’s electronics.
Sealing Rings:
These rings create a gas-tight seal between the insulator and the metal housing, preventing combustion gas leaks.
