What is ignition coil?

• Automobile ignition system is mainly composed of ignition power, ignition switch, ignition coil, spark plug and spark wire.
• The spark plug is used for ignition, and the ignition coil is used to provide energy to the spark plug.
• How does the ignition coil provide energy: The ignition coil is like a transformer that increases the 12V voltage of the battery to a high voltage of tens of thousands of volts; at the same time, it is an energy storage device to ensure that the spark plug continues sparking. The ignition coil is made using the principle of electromagnetic mutual induction.

• The plastic parts made by BASF
• The epoxy from Sino-Japan joint venture enterprise
• The enameled copper wire from the ELEKTRISOLA

• 100% 38-40KV open circuit test (higher than other factory's checking standard of 35KV)
• Complete quality inspection process: Material check - First check - Check by oneself - IPQC - 100% 38-40KV open circuit test - Shipment inspection
• Insist on quality first, the proportion of defective products is above 6% and the whole batch is scrapped
• The factory has equipment of automatic winding machines, automatic vacuum filling machines, and automatic assembly lines to ensure product production efficiency and consistency.

• Unstable idle speed: Design or aging causes insufficient ignition energy. Lack of cylinder or fire in cylinder
• The car trembles during driving: Lack of cylinder or poor ignition in cylinder
• Cold car normal but hot car shaking: The ignition module does not work normally when it reaches a certain temperature. Wrong ignition coil parameters.
• The car doesn't have enough fuel: Insufficient ignition energy due to aging or design.
