Introduction

The Exhaust Recirculation Cooler Kit 4955518 by Cummins is designed to enhance the operation of commercial trucks by managing exhaust emissions. This kit is integral to the truck’s emission control system, ensuring compliance with environmental regulations while maintaining engine performance ¹.

Basic Concepts of Exhaust Recirculation Cooler Kits

Exhaust Recirculation Cooler Kits operate on the principle of recirculating a portion of the engine’s exhaust gas back into the intake system. This process reduces the formation of nitrogen oxides (NOx) by lowering the combustion temperature. The cooler within the kit plays a role in this system by cooling the recirculated exhaust gases before they are reintroduced into the engine, which further aids in reducing emissions and improving engine efficiency ².

Purpose and Role in Truck Operation

The 4955518 Exhaust Recirculation Cooler Kit is designed to integrate seamlessly into the truck’s engine system. Its primary function is to cool the recirculated exhaust gases, which helps in reducing emissions and enhancing engine performance. By lowering the temperature of the exhaust gases, the kit contributes to more efficient combustion and helps in meeting stringent emission standards ³.

Key Features

This Cummins part is constructed with high-quality materials to ensure durability and efficiency. Its design includes a robust cooling mechanism that effectively reduces the temperature of the recirculated exhaust gases. Additionally, the kit is engineered to be compatible with a range of Cummins engines, ensuring a reliable fit and function.
