Introduction

The Cummins Master Piston 3871475 is a component designed for use in commercial truck engines. It plays a role in the engine system by contributing to the overall operation and efficiency of the vehicle. Understanding its function and significance is important for maintaining and optimizing the performance of commercial trucks.

Basic Concepts of Master Pistons

A master piston is a key component within an engine, responsible for converting the energy from fuel combustion into mechanical motion. It operates by moving up and down within the cylinder, driven by the pressure generated during the combustion process ¹. This motion is then transferred through the connecting rod to the crankshaft, which converts the linear motion of the piston into rotational motion to drive the vehicle. The master piston interacts with other engine components, such as the cylinder walls, piston rings, and valve train, to ensure smooth and efficient engine operation.
