Diesel oksidacijski katalizator

DOC (Diesel oxidation catalyst) is a device installed in the exhaust system of diesel vehicles to reduce exhaust emissions. DOC is the first step in the aftertreatment of exhaust gas, and it is also a device that converts CO and hydrocarbons in exhaust gas into harmless CO2 and H2O.

Excessive sulfur and phosphorus elements are produced in the exhaust gas, which can easily lead to the failure of the DOC device.

Therefore, the National VI diesel engine oil should not only have low ash content, but also a low sulfur and low phosphorus formula.

DOC technical features:

1. The precious metals are mainly Pt or Pt and Pd;

2. The DOC slurry is configured by dipping;

3. Other auxiliary materials are added to increase the conversion rate and reduce the light-off temperature.

Konkurentna prednost:

1. Dobra disperzija plemenitih metala;

2. Niža temperatura paljenja;

3. Dobra otpornost na visoke temperature;

4. Dobra anti-toksičnost

5. Indikatori vijeka trajanja: 50,000 kilometara za vozila u upotrebi i 200,000 kilometara za nova proizvodna vozila.
