EGR SYSTEM OPERATION [YF (2.0L Zetec)]
BUE011600020N09
• The high occurrence of NOx at high temperatures has been reduced by recirculating exhaust gas to the combustion chamber in order to lower the combustion temperature.
• Exhaust gas flows through the EGR pipe and into the EGR valve. The exhaust gas flow amount controlled by the EGR valve is conducted to the intake manifold.
