Convert low voltage electricity to high voltage electricity to ignite the engine mixture

The ignition coil is the core component of the car ignition system.

Its core function is to convert the low voltage (12V) provided by the battery into high voltage (15000-30000V) through electromagnetic induction principle, drive the spark plug to generate electric sparks, ignite the mixture in the engine cylinder, and ensure the normal operation of the engine.  ‌

Detailed Function Analysis

Voltage conversion function
 

The ignition coil is essentially a transformer, consisting of a primary coil, a secondary coil, and an iron core. The primary coil receives 12V low voltage electricity from the battery and generates high voltage electricity from the secondary coil through electromagnetic induction to meet the voltage required for spark plug ignition.
 

If the voltage conversion is insufficient, it will lead to insufficient combustion of the mixture, causing problems such as decreased power and increased fuel consumption.
 

Ensure stable operation of the engine

Modern engines pursue high speed and low emissions, and the high energy output of the ignition coil is the key to meeting this demand.

Sufficient ignition energy can ensure reliable ignition of spark plugs under extreme working conditions, such as high compression ratios.
 

When there is a malfunction, there may be cylinder shortage, shaking or stalling, which directly affects driving safety.
 

Collaborative work with ignition system

The ignition coil needs to be coordinated with a switch device (such as an ECU controlled transistor) to precisely control the ignition timing. Some models use independent ignition coils (one per cylinder) to improve response speed and energy efficiency.
 

If the spark plug gap is abnormal or the high-voltage wire is damaged, it will also damage the ignition coil and require synchronous maintenance.
 

Supplementary explanation

Type difference: divided into open circuit and closed circuit, with the latter being more efficient; Some designs include additional resistors to optimize voltage stability.
 

Maintenance suggestion: It is usually replaced every 100000 kilometers, but regular checks should be conducted for signs of erosion, cracks, or high-temperature aging.
 

Summary: The ignition coil is the "energy hub" for efficient combustion in engines, and its performance directly affects power output, emissions, and reliability.
