Basic Concepts of Exhaust Gas Recirculation (EGR)

Exhaust Gas Recirculation (EGR) technology involves redirecting a portion of an engine’s exhaust gas back into the intake air stream. This process reduces combustion temperature, thereby lowering the formation of nitrogen oxides (NOx), a harmful emission. Additionally, EGR can improve engine efficiency through leaner combustion, potentially leading to better fuel economy. This technology is crucial for meeting stringent emissions regulations and enhancing the overall performance of diesel engines ¹.

Functionality of the 3691354 Exhaust Gas Recirculation Venturi

The 3691354 EGR Venturi operates based on fluid dynamics and pressure differentials. It is designed to control the flow of exhaust gases recirculated back into the engine’s intake. By creating a pressure drop, the venturi facilitates the mixing of exhaust gases with the intake air, ensuring a consistent and controlled EGR rate. This precise control is essential for maintaining optimal engine performance and emissions levels ².
