IGNITION COIL CONSTRUCTION [L3]

BME011818100T01

• The ignition coil contains two coils. They are for cylinder numbers 1 and 4, and cylinder numbers 2 and 3 respective. (Matched pairs)

• The two secondary terminals contain the secondary coils positive and negative terminals. The closed circuit of secondary coils is formed through the high-tension leads, two spark plugs and the cylinder head. Due to this, one coil ignites two cylinders simultaneously.

• The firing timing of the coil is controlled by the PCM due to built-in ignition system.
