Engine Brake Slave Piston
Cummins®

Introduction

The Engine Brake Slave Piston 2882738, manufactured by Cummins, is a critical component in the engine braking systems of heavy-duty trucks. This Cummins part enhances the efficiency and safety of these vehicles by facilitating engine compression braking.

Basic Concepts

Engine brake systems utilize engine compression to slow vehicles, reducing reliance on friction brakes. The Engine Brake Slave Piston plays a role in this system by actuating the valve train to create compression within the cylinders, effectively slowing the vehicle ¹.

Functionality of the Engine Brake Slave Piston

This part operates by converting hydraulic pressure into mechanical force. Upon engaging the engine brake, hydraulic fluid is directed to the slave piston, causing it to move and interact with the valve train components to open the exhaust valves. This action creates resistance within the engine, slowing the vehicle. The precise timing and force application of the slave piston are essential for the efficient operation of the engine brake system ².

Purpose of the Engine Brake Slave Piston 2882738
