Womala Auto Parts EGR Valve 11717563241 11718479590 for Bmw 1/3/5 Series

Product Details: EGR Valve (Exhaust Gas Recirculation Valve) - 11717563241

This Exhaust Gas Recirculation (EGR) valve is a precision-engineered emissions control component designed to reduce nitrogen oxide (NOx) emissions by recirculating a portion of exhaust gases back into the engine intake manifold . It ensures optimal engine performance, fuel efficiency, and compliance with emissions standards. This electric EGR valve features a 5-pin rectangular connector and is constructed from durable metal materials for long-lasting performance .

Core Function: The EGR valve regulates the flow of exhaust gases into the combustion chamber, lowering combustion temperatures and reducing harmful NOx emissions . It provides the connection between the exhaust manifold and the inlet manifold, collecting part of the gases and reintroducing them into the cylinders to start a new cycle . A properly functioning EGR valve is essential for smooth engine operation, preventing knocking, and maintaining fuel economy.

Failure Symptoms: Carbon buildup from exhaust gases is the primary cause of failure, which can cause the valve to stick open or closed. A stuck open valve affects air-fuel ratio, resulting in reduced power and fuel efficiency. A valve stuck closed causes high combustion chamber temperatures, increased emissions, and potentially engine knock (pre-ignition) which can severely damage an engine.
