3.2 ECU：
ECU shall be used in a closure, dry and clean environment.
3.3 Harness
The range of application temperature: -40℃~105℃
3.4 Post-processing system
The DOC shall be cleaned up regularly to prevent excessive carbon accumulation to affect the performance of engine.
3.5 EGR valve:
Technical parameters:
Exhaust gas flow Maximum flow of 180kg/h with △P=50hPa
Air leakage volume with △P=600hPa <0.5 kg/h
Maximum allowable environmental temperature -40 - 150℃
Maximum allowable temperature of actuator 200℃
Range of exhaust gas temperature at exhaust gas inlet 150 - 550
℃
Rated current 1.5A
Maximum allowable acceleration axial/radial direction 30g
Mass 0.7kg
Feedback of position signal Available
Position installation (relative to perpendicular line) Within ±85°
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.
Max. allowable temperature of valve parts:
13.07
position sensor 175℃
Driving motor 200℃
transmission box 200℃
valve guiding axle 350℃
mixing chamber 400℃
exhaust inlet 550℃
