Introduction

The Cummins 3646328NX Cylinder Head is a critical component in the engine systems of heavy-duty trucks. It is engineered to enhance engine performance and efficiency. This part is integral to the operation of the engine, contributing to the overall functionality and reliability of the vehicle.

Basic Concepts of Cylinder Heads

A cylinder head is a fundamental part of an internal combustion engine. It sits atop the engine block and houses the combustion chamber, valves, and spark plugs (in gasoline engines) or fuel injectors (in diesel engines) ¹. The cylinder head’s primary function is to seal the combustion chamber, allowing for the compression and combustion of the air-fuel mixture. It also facilitates the intake and exhaust of gases through its valves, which open and close in synchronization with the engine’s operation ².
