Ignition Coil A0001502580 For Mercedes Benz W204 W203 W212 W211

Automobile ignition coil is a device for generating high voltage, which converts low voltage electric energy into high voltage to ignite the fuel mixture of the engine. Its structure usually includes the following parts:

1. Primary Coil: The primary coil is the low-voltage side of the ignition coil and is usually made of thick copper wire. It is connected to the power supply circuit of the vehicle and receives a low voltage (usually 12 volts) from the battery.

2. Secondary Coil: The secondary coil is the high-voltage side of the ignition coil, and it is usually made of filaments. It is connected with the primary coil through magnetic coupling to convert low voltage into high voltage.

3. Core: The core is the magnetic circuit part of the ignition coil and is usually made of iron or magnetic materials. Its function is to enhance the magnetic field and improve the magnetic coupling efficiency.

4. Ignition Switch: The ignition switch is a switch that controls the energization of the ignition coil, usually controlled by the key or button of the vehicle. When the ignition switch is turned on, the current flows through the primary coil to generate a magnetic field.

5. High Voltage Output Terminal: The high voltage output terminal is the output port of the ignition coil, and the high voltage is transmitted to the spark plug through the high voltage wire to ignite the fuel mixture.

According to the type of ignition coil, it can be divided into the following categories:

1. Conventional Coil: Conventional coil is the most common type of ignition coil, which uses the structure of primary coil and secondary coil. It is usually surrounded by an iron core to enhance the magnetic field effect.

2. Distributor Coil: A distributor-integrated ignition coil is used. It comprises a primary coil, a secondary coil and a distributor, and is used for distributing high voltage to each spark plug.

3. Independent coil: Independent coil is a design with independent ignition coil for each cylinder. Each coil is connected to a spark plug to achieve more accurate ignition control.

4. Direct Ignition Coil: The direct ignition coil is a highly integrated coil directly installed on each spark plug. It controls the ignition timing by electric pulse, providing more accurate and efficient ignition.

It should be noted that different models and engine types may use different types of ignition coils. The specific coil structure and type may be different. Therefore, when repairing and replacing the ignition coil, it is best to refer to the owner's manual of the vehicle or consult a professional automobile maintenance technician.
