Introduction

The Exhaust Recirculation Valve Support (Part #2870112) is a component manufactured by Cummins, designed to enhance the functionality of the exhaust recirculation system in commercial trucks. This part is integral to the system’s operation, ensuring efficient recirculation of exhaust gases to reduce emissions ¹.

Basic Concepts of Exhaust Recirculation

The Exhaust Recirculation (EGR) system is designed to lower nitrogen oxides (NOx) emissions, which are harmful pollutants produced during the combustion process. The EGR system works by recirculating a portion of the engine’s exhaust gas back into the intake manifold. This process dilutes the oxygen concentration in the intake air, thereby reducing the peak combustion temperature and the formation of NOx. The system comprises several components, including the EGR valve, cooler, and associated piping and supports ².

Function of the Exhaust Recirculation Valve Support

The Exhaust Recirculation Valve Support plays a role in the EGR system by providing structural stability to the EGR valve. It ensures that the valve remains securely in place and operates efficiently. This support is crucial for maintaining the alignment and integrity of the EGR valve, which is responsible for controlling the flow of exhaust gases into the intake system ³.

Key Features of Part #2870112

The Exhaust Recirculation Valve Support is constructed from durable materials that offer high resistance to heat and corrosion.

Understanding the Role of Part 2870112 in Exhaust Recirculation Systems

Part 2870112, the Exhaust Recirculation Valve Support, is an integral component in the orchestration of exhaust recirculation (EGR) systems within engine assemblies. This support structure is designed to provide a stable mounting point for the EGR valve, ensuring its proper function and integration within the engine’s emission control strategy.

Integration with the EGR Valve

The EGR valve is a pivotal component in reducing nitrogen oxides (NOx) emissions by recirculating a portion of the engine’s exhaust gas back into the intake manifold. The Exhaust Recirculation Valve Support, part 2870112, secures the EGR valve in place, allowing it to operate efficiently under varying engine conditions. This support ensures that the valve can open and close as needed, regulated by the engine control unit (ECU), to maintain optimal emission levels.

Interaction with the Intake Manifold

The intake manifold is responsible for distributing the air-fuel mixture to the engine’s cylinders. The EGR system, supported by part 2870112, interfaces with the intake manifold to introduce recirculated exhaust gases. This interaction is essential for diluting the air-fuel mixture, which lowers combustion temperatures and subsequently reduces NOx emissions. The secure mounting provided by the Exhaust Recirculation Valve Support is vital for maintaining the integrity of this connection.

Coordination with the Engine Control Unit (ECU)

The ECU plays a significant role in managing the EGR system’s operation. It monitors various engine parameters and adjusts the EGR valve’s position accordingly. Part 2870112 ensures that the EGR valve remains in the correct position and operates smoothly, allowing the ECU to effectively control the recirculation process. This coordination is essential for the EGR system to function as intended, contributing to the engine’s overall efficiency and emission compliance.

Contribution to Emission Control

By supporting the EGR valve, part 2870112 indirectly contributes to the engine’s emission control efforts. The stable mounting allows for precise control over the amount of recirculated exhaust, which is crucial for meeting environmental regulations. The Exhaust Recirculation Valve Support ensures that the EGR system can operate within the parameters set by the ECU, facilitating a reduction in harmful emissions.
