Ignition Coil
Cummins®

The Cummins 5626388 Ignition Coil is a critical component designed for use in commercial trucks. Its primary function is to facilitate the ignition process within the engine, ensuring that the air-fuel mixture combusts efficiently. This ignition coil is integral to the operation of the truck, contributing to engine performance and reliability.

Basic Concepts of Ignition Coils

An ignition coil is a transformer that converts the low voltage from the battery into the high voltage needed to create a spark in the spark plugs. This process is based on the principles of electromagnetic induction. When current flows through the primary winding of the coil, it generates a magnetic field. Interrupting this current causes the magnetic field to collapse, inducing a high voltage in the secondary winding. This high voltage is then directed to the spark plugs, where it creates a spark that ignites the air-fuel mixture in the combustion chamber ¹.

Role of the 5626388 Ignition Coil in Truck Operation

The Cummins 5626388 Ignition Coil plays a specific role in the operation of a truck by generating the high-voltage spark required for igniting the air-fuel mixture in the combustion chamber. This function is vital for engine start-up and sustained operation. The efficient generation of this spark ensures that the engine runs smoothly, with optimal combustion efficiency ².
