Cummins®

The 5373046 Ignition Coil, manufactured by Cummins, is a component designed to enhance the ignition system of commercial trucks. Cummins, a well-established name in the automotive industry, produces this ignition coil to ensure reliable and efficient engine performance. This part is integral to the operation of commercial trucks, contributing to the overall functionality and efficiency of the engine.

Basic Concepts of Ignition Coils

An ignition coil is a vital component in an engine’s ignition system. Its primary function is to transform the battery’s low voltage into the high voltage needed to create a spark in the spark plugs. This spark ignites the air-fuel mixture in the engine’s cylinders, facilitating combustion and powering the vehicle. The ignition coil operates on the principle of electromagnetic induction, where a changing magnetic field within the coil induces a high voltage in the secondary winding ¹.

Operation of the 5373046 Ignition Coil

This Cummins part operates by utilizing two windings: a primary winding and a secondary winding. When the ignition system sends a low voltage current through the primary winding, it creates a magnetic field. When this current is interrupted, the magnetic field collapses, inducing a high voltage in the secondary winding. This high voltage is then sent to the spark plugs, where it creates the spark necessary for combustion ².

Purpose of the 5373046 Ignition Coil in Truck Operation

In the ignition system of commercial trucks, this part plays a significant role by ensuring that the spark plugs receive the necessary high voltage to ignite the air-fuel mixture efficiently. This contributes to the engine’s performance and efficiency, allowing for smoother operation and potentially improving fuel economy. The reliable ignition provided by this coil is crucial for the consistent operation of commercial trucks, which often operate under demanding conditions.
