EGR System Fouling Control
Exhaust gas recirculation (EGR) is effective in reducing engine-out NOx emissions; however, the EGR system is subject to fouling and corrosion. Fouling is mainly due to particulate buildup on the EGR component (e.g., EGR valve and cooler) surfaces. Corrosion is primarily related to oxides of sulfur and nitrogen in the gas stream, especially problematic when condensation occurs [1]. Because cooled EGR is most effective in controlling NOx emissions, EGR cooler design and operation are important considerations in engine design in order to meet durability requirements. An approach has been developed to greatly reduce EGR system fouling. Four EGR coolers were tested simultaneously with various PM control devices installed upstream of the cooler. System configuration and on-engine test results are presented herein.
