الوصف

Exhaust Gas Recirculation (EGR) Valves re-circulate metered amounts of 

exhaust gas into engines's intake system to help limit the formation of 

nitrogen oxide (NOx) emissions,also control driveability,octane rating 

and fuel economy. The reducation of NOx is accomplished by lowering 

engine combustion emperature by recirculating metered amounts of burned 

exhaust gases back through the intake manifold where they ate mixed with 

fresh air-fuel mixture. The EGR device with position sensor provides 

feedback tothe engine computer so that precise flow control is possible 

in order to achieve desirable operating conditions and have quick 

response in the dynamic mode.
