What is the service life of platinum spark plugs?
1 Answers
The service life of platinum spark plugs is 20,000-30,000 kilometers. Below is detailed information about automotive spark plugs: 1. Overview: Automotive spark plugs, commonly known as sparking plugs, function by discharging the pulsed high-voltage electricity sent from the high-tension leads (spark plug wires), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. They can be broadly categorized into standard spark plugs and insulator-protruding spark plugs. 2. Additional Information: The fundamental requirements for a high-performance engine include a stable high-energy spark, a uniformly mixed air-fuel mixture, and a high compression ratio. The key component of a spark plug is the insulator. The insulator of a spark plug must possess excellent mechanical properties, high voltage resistance, high-temperature impact resistance, and chemical corrosion resistance. Ordinary spark plugs are typically made of alumina-based ceramics.
