Following NOx catalytic converter error messages:

180401 NOx catalytic converter: Efficiency below limit

 

Following diagnostics live data:

Stratified charge: disabled

The engine performs Homogeneous injection mode only



  • Increased fuel consumption
  • 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

  • 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 operation of 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



Attention! While using NOXEM 402 NOx sensor emulator, the NOx level, emitted by the engine in some modes can differ from value, specified by the manufacturer. The user of the product assumes full responsibility for compliance with emission standards, valid in the country of use.

NOXEM restores the normal performance of the NOx system, which is one of the main conditions for correct engine performance. Affirmation for the successful performance of NOXEM – no new error messages regarding NOx sensor in the memory of MSD87 (exception: 12C401, detailed information read here). However, NOXEM does not guarantee the excellent performance of the engine, if the engine has others, not related to NOx system, defects and/or the required coding procedures (clearing of adaptations and re-adaptation of the engine) after installing NOXEM are not performed correctly/not performed at all.
