The basic composition of exhaust gas after-treatment system

The diesel engine exhaust gas after-treatment system is mainly composed of catalytic converters (DOC, DPF, SCR), urea tanks, nozzles, sensors, and control units.

Key Technology of Diesel Engine After Treatment:

Increase the conversion rate of the catalytic converter to carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOX), complete particulate matter at a lower temperature, and reduce exhaust pressure. A high-precision control system is a key to reducing emissions.

Feature:

  1. Low ammonia leakage ≦5ppm, low ignition temperature ≦200℃
  2. Large ammonia storage capacity and wide temperature range
  3. Low resistance, low temperature, and high activity, high NOX removal rate, saving operating costs
  4. High water resistance, high-temperature corrosion resistance, high mechanical strength, and heat resistance
