℃
~105
℃
3.4 Post-processing system
The DOC shall be cleaned up regularly to prevent excessive carbon accumulation to affect the performance of engine.

Temperature requirements
The inlet temperature at EGR valve shall not be over 550
℃
, or else the valve may be damaged; and the exhaust gas
temperature shall be above 150
℃
to avoid carbon accumulation. For the valve eliminating the carbon deposit
automatically under the temperature of above 300
℃
, it is recommended that the inlet temperature at valve shall
reach this temperature regularly to eliminate carbon deposit.
