Product Description:

Electrical ignition coil
OE NO.:  8687939 30684245

Applicable vehicle type: For Volvo

The automotive ignition coil is a key component of the engine ignition system, whose function is to convert the low-voltage direct current provided by the vehicle's power source into high-voltage electricity as high as tens of thousands of volts, providing the high-voltage spark required for the spark plug to ignite.

As a critical component of the engine ignition system, automotive ignition coils offer multiple advantages and characteristics:

• Delivering High-Energy Sparks for Reliable Ignition: The primary function of an ignition coil is to generate high-voltage sparks reaching tens of thousands of volts, forming the foundation of engine ignition. High-performance ignition coils provide ample spark energy, ensuring reliable ignition of the fuel-air mixture under various operating conditions (cold starts, high speeds, lean burn, etc.). This prevents engine issues such as unstable idle, vibration, and power loss.
• High durability and extended lifespan: Modern automotive ignition coils incorporate premium materials and manufacturing processes to ensure long-term reliability in harsh engine environments. Under normal usage, high-quality ignition coils can last over 100,000 kilometers, with some high-performance models exceeding 150,000 kilometers. This eliminates the need for frequent replacements during the vehicle's lifecycle, reducing maintenance costs and operational risks.
• Energy Efficiency and Low Loss: New ignition coil designs prioritize enhancing energy conversion efficiency while minimizing energy dissipation. High-performance ignition coils contribute to improved engine fuel economy, reduced energy consumption, and lower emissions.
• Compact Design and Integration: As automotive manufacturers increasingly prioritize engine compartment space optimization and weight reduction, ignition coil designs are evolving toward miniaturization and integration. Many new ignition coils feature plastic housings and compact structures, offering smaller dimensions and lighter weight for easier installation within limited engine compartments. This compact design not only saves installation space but also enhances the overall reliability and interference resistance of the ignition system.
• Precise Ignition Control and Diagnostics: Advanced ignition coils integrate electronic control and diagnostic functions, enabling precise control of the ignition process and real-time status monitoring. Smart ignition coils dynamically adjust ignition timing and energy output in real-time based on engine conditions, optimizing combustion efficiency and power delivery. Concurrently, built-in diagnostic circuits monitor coil operation. Upon detecting faults—such as primary/secondary winding short circuits, open circuits, or excessive temperatures—they promptly transmit fault signals to the ECU, alerting drivers or technicians to replace the component. This active diagnostic capability enhances system reliability and safety, reducing the risk of engine damage caused by ignition failures.

In summary, automotive ignition coils offer significant advantages in delivering reliable ignition, high durability, energy efficiency, and intelligent control, making them indispensable components in modern automotive engines. As automotive technology advances, high-performance ignition coils will continue to evolve toward higher energy output, smarter control, and greater environmental efficiency.
