Introduction

The Cummins 3406605 Injector Cup is a component designed for use in heavy-duty trucks, specifically within the fuel injection system. It ensures the integrity of the fuel system and facilitates proper fuel delivery, which is vital for the efficient operation of diesel engines ¹.

Basic Concepts of Injector Cups

An injector cup, also known as a fuel cup or injector sleeve, is a cylindrical component that houses the fuel injector within the engine cylinder. It serves as a seal between the injector and the cylinder, preventing fuel leakage into the combustion chamber. The injector cup interacts with the injector, cylinder head, and fuel system to maintain the pressure and purity of the fuel as it is delivered to the engine ².

Purpose of the Cummins 3406605 Injector Cup

This Cummins part plays a role in the operation of a truck by maintaining the integrity of the fuel system. It ensures that fuel is delivered to the injector under the correct pressure and without contamination. This component helps in achieving efficient combustion, which contributes to the overall performance and efficiency of the engine ³.
