Following NOx catalytic converter error messages:

30E9 nitric oxide catalytic converter, aging

30EA nitric oxide catalytic converter, sulphurized*

*if an error appears repeatedly and/or forced desulfurization is not possible/successful

 

Following diagnostics live data:

NOx concentration is 0 ppm**

(INPA data | NOx Sensor / Exhaust temperature menu) after:

• the engine is warmed up
  
• exhaust temperature is more than 220 oC
• driving speed exceeds 20 km/h for more than 2 min

**continuously or periodically: the sensor is damaged

---

• Rough idle (cold and/or hot engine)
• Uneven run at mid/high loads
• Misfires and error messages about misfires
• Error messages about cylinder’s and/or bank’s fuel trim
• Problems with cold engine start
• Increased fuel consumption

---

 

 

 

• Restores normal operation of NOx system and fuel economy
• DOES NOT require NOx catalytic converter replacement
• Restores creation of cylinders individual and bank fuel adaptations for idle, mid/high loads, cold engine – smooth operation at all conditions
• Restores Stratified charge and Homogeneous lean fuel injection modes, regeneration, and desulfation of NOx catalytic converter
• Increased lifetime: average more than 300’000 km

NOXEM series NOx emulator is built using the highest quality components

• Bosch’s latest-generation sensor, controlled and measured by ourselves developed analog control module provides the highest accuracy of exhaust Lambda value. Now you can use NOx emulator Lambda data as reference
• Up to 30V overvoltage and wrong supply polarity protection guarantee highest resistance to cars on-board voltage spikes
• High precision reference frequency oscillator and industrial temperature grade components provide uninterruptible operation in a wide temperature range
• High power oversized sensor control stage reduce heating and facilitate the operation of the electronics module at high temperatures
• Double sealed construction with 5mm stainless steel base plate is a guaranty of long and safe operation in hard environment conditions

Electrical characteristics

• Power supply: +9.0 .. +16.0V DC
• Long-term over-voltage (1 hour): +24.0V DC
• Short-term over-voltage (1 second): +30.0V DC
• Wrong polarity short-term over-voltage (1 second): -30.0V DC
• Maximal current consumption (+14.0V DC; +25oC): 2.5A
• Average current consumption (+14.0V DC; +25oC): 0.8A
• Operation temperature: -40oC .. +105oC
