Exhaust Recirculation Valve Kit Components

Exhaust Recirculation Valve

The Exhaust Recirculation Valve is the core component of the kit. It plays a role in controlling the flow of exhaust gases that are recirculated back into the engine’s intake system. This process helps to reduce nitrogen oxide emissions by lowering the combustion temperature in the cylinders.

Gasket

The gasket is a sealing component that ensures a tight fit between the Exhaust Recirculation Valve and the engine block or intake manifold. It prevents leaks of exhaust gases and ensures that the valve operates efficiently.

Mounting Bracket

The mounting bracket secures the Exhaust Recirculation Valve to the engine. It provides a stable and durable attachment point, ensuring that the valve remains in the correct position and functions properly under various operating conditions.

Vacuum Hose

The vacuum hose connects the Exhaust Recirculation Valve to the engine’s vacuum source. It allows the valve to be actuated by engine vacuum, enabling precise control over the amount of exhaust gas recirculation.

Electrical Connector

The electrical connector links the Exhaust Recirculation Valve to the engine’s electronic control unit (ECU). This connection allows the ECU to monitor and adjust the valve’s operation based on real-time engine data, optimizing performance and emissions.

Solenoid

The solenoid is an electromechanical device that controls the opening and closing of the Exhaust Recirculation Valve. It receives signals from the ECU and uses magnetic force to move the valve, ensuring accurate and timely recirculation of exhaust gases.

O-Ring

The O-ring is a small, circular seal that prevents leaks around the connections of the Exhaust Recirculation Valve. It ensures that the valve maintains a secure and leak-free seal, contributing to the overall efficiency and reliability of the system.

Bolts and Nuts

Bolts and nuts are used to secure various components of the Exhaust Recirculation Valve Kit in place. They provide the necessary tension and stability to ensure that all parts remain firmly attached and function correctly.

Wiring Harness
