Emission Control Exhaust Gas Recirculating Delay Solenoid

The Emission Control Exhaust Gas Recirculating (EGR) Delay Solenoid is a component of the Engine Electrical System in non-aircraft engines. It belongs to the supply class Engine Electrical System Components and falls under the supply group Engine Accessories.

The EGR system is designed to reduce nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gases back into the engine's intake manifold. The EGR Delay Solenoid is responsible for controlling the timing and duration of the EGR valve operation.

When the engine is running, the EGR Delay Solenoid receives signals from the engine control unit (ECU) to open or close the EGR valve at specific times. By delaying the opening and closing of the EGR valve, the solenoid helps optimize the engine's performance and emissions.

The EGR Delay Solenoid is typically a small, electrically operated valve that is mounted near the EGR valve. It is connected to the ECU through electrical wiring and receives commands to regulate the EGR valve's operation.

Overall, the Emission Control Exhaust Gas Recirculating Delay Solenoid plays a crucial role in controlling the EGR system's functionality, ensuring proper emissions control and engine performance.
