• 121-6304 1216304 Coil Excavator Electric Parts Fitting For C9 C13 325B 330D 345D

• Specification

• Function

1.Ignition system support: In gasoline engines, the 121-6304 coil may supply the high voltage needed for spark plugs to create a spark. This spark ignites the compressed air-fuel mixture in the combustion chamber, enabling the engine to generate power. A reliable coil ensures consistent ignition timing and intensity, which is critical for engine performance, fuel efficiency, and emissions control.

2.Fuel injector control: In some diesel engine systems, such coils can actuate fuel injectors by converting low-voltage electrical signals into mechanical motion. This precise control of injector opening and closing times ensures accurate fuel delivery, optimizing combustion efficiency and engine operation.
