Cummins®

The Cummins Injector Cup, identified by part number 3018863, is a component integral to the fuel injection system of heavy-duty trucks. Its purpose is to ensure the proper functioning of the fuel injector by maintaining a seal and providing a secure mounting point. The significance of this Cummins part lies in its role in preserving the integrity of the fuel system and facilitating efficient fuel delivery, which are vital for the overall performance and reliability of the truck ¹.

Basic Concepts of Injector Cups

An injector cup is a cylindrical component that houses the fuel injector within the engine’s cylinder head. Its primary function is to create a seal between the injector and the cylinder head, preventing fuel leakage and ensuring that fuel is delivered precisely into the combustion chamber ². The injector cup also plays a role in dissipating heat generated by the injector, thereby protecting surrounding components from thermal damage. It interacts closely with the fuel injector, cylinder head, and other elements of the fuel injection system to maintain optimal engine operation.
