Effects of sulfur on SCR after-treatment system:
SCR catalyst is sensitive to sulfur, sulfur in the exhaust gas easily lead to poisoning of the catalyst deactivation.
There will be the normal operation of the engine in a small amount of lubricating oil through combustion piston rings and cylinder walls into the combustion chamber.
The lubricating oil mainly from S sulfonates, metal alkyl phenates detergents, ZDDP, a number of sulfur-containing antioxidants, friction modifiers, etc.
Engine oil into the combustion chamber after the sulfur is oxidized to SO2, SO3, etc. into the exhaust gas, S is the position occupied by the oxides in catalysis, compete with other exhaust gas on the catalyst surface, inhibiting catalyst performance, leading to catalytic poisoning, inactivation .
At present, the sulfur content in the lubricating oil is typically 0.4 to 0.8%.
