EXHAUST GAS RECIRCULATION SYSTEM OPERATION [L8, LF]

id0116a3149200

• 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.
• The exhaust gas flows along the EGR passage in the cylinder head and into the EGR valve. Exhaust gas that has flowed past the EGR valve flows through the EGR pipe, and is conducted to the dynamic chamber.
