Cummins®

Introduction

The Exhaust Gas Recirculation Module Support, part number 5266802, is a component produced by Cummins, a prominent manufacturer in diesel engine technology. This part is essential for the operation of the exhaust gas recirculation (EGR) system in commercial trucks, contributing to engine performance and emissions control.

Basic Concepts of Exhaust Gas Recirculation

Exhaust Gas Recirculation (EGR) systems are integral to modern diesel engines, aimed at reducing nitrogen oxides (NOx) emissions. These systems work by recirculating a portion of the engine’s exhaust gas back into the intake, which lowers the combustion temperature and subsequently reduces NOx formation. This not only helps in adhering to stringent emissions regulations but also enhances engine efficiency by optimizing the combustion process ¹.

Function of the Exhaust Gas Recirculation Module Support

The Exhaust Gas Recirculation Module Support acts as a foundational component within the EGR system. It provides a stable mounting platform for the EGR module, ensuring its secure positioning. This support is crucial for the efficient operation and integration of the EGR system with the engine’s intake system. The recirculation of exhaust gases is controlled by a valve within the EGR module, and the support ensures the system’s integrity and alignment.

Key Features of the 5266802 Exhaust Gas Recirculation Module Support

Engineered with durability in mind, the 5266802 Exhaust Gas Recirculation Module Support is constructed from high-strength materials to withstand the demanding conditions of commercial truck operations.
