What is the spark plug model for Mercedes-Benz GLA?
1 Answers
The spark plug model for Mercedes-Benz GLA is NGK Iridium Platinum Spark Plug 90654 (sparkplug), commonly known as a spark plug. Its function is to discharge the pulsed high voltage sent by the high-voltage wire (spark plug wire), break down the air between the two electrodes of the spark plug, and generate an electric spark to ignite the mixed gas in the cylinder. Below is relevant information about spark plugs: 1. The insulator of a spark plug must have good mechanical properties, high voltage resistance, high-temperature impact resistance, and chemical corrosion resistance. Ordinary spark plugs are mostly made of alumina-based ceramics. 2. The size of spark plugs is standardized worldwide and can be used universally in any car. However, due to differences in gasoline engine types, spark plugs are divided into two basic types: cold type and hot type. 3. Cold type and hot type are relative terms, reflecting the thermal characteristics of the spark plug. A spark plug must maintain an appropriate temperature to function properly, and it must be free of carbon deposits to operate normally.
