Emission Control Exhaust Gas Recirculating Timer Switch

The Emission Control Exhaust Gas Recirculating (EGR) Timer Switch is a component that is part of the supply class Miscellaneous Engine Accessories, specifically in the Nonaircraft category. It falls under the supply group Engine Accessories.

The EGR system is designed to reduce emissions by recirculating a portion of the exhaust gases back into the engine's intake manifold. The EGR Timer Switch is responsible for controlling the timing of the EGR valve, which regulates the flow of exhaust gases into the intake manifold.

By controlling the timing of the EGR valve, the EGR Timer Switch helps optimize the engine's performance and reduce emissions. It ensures that the recirculation of exhaust gases occurs at the appropriate times, based on factors such as engine load, temperature, and speed.

Overall, the Emission Control Exhaust Gas Recirculating Timer Switch is an important component in the EGR system, contributing to the reduction of harmful emissions from nonaircraft engines.
