Sellers’ Notes Checklist


 Important things

 

1

• This product is suitable for highway diesel vehicles with good vehicle condition and normal exhaust temperature.

 

2

• Usually PT/10gr ft³/PT/20gr ft³ corresponds to the original vehicle size of the emission standard, which is enough to achieve the corresponding emission effect. Since ours is a replacement product, not the original, there is a difference in precious metal content with the original DOC. If you mind this situation, don't pay.

 

3

• If you have any requirements for PD, RH, Or there are higher requirements for precious metal content
• Please contact us.

 

4

• For non-road equipment, the engine exhaust temperature is relatively low, such as generators/mining equipment, etc. It needs to be judged based on factors such as working environment/power/exhaust temperature, please contact us.

 

5

• We have super stock, PT/5gr ft³/PT/10gr ft³/PT/15gr ft³/PT/20gr ft³/PT/30gr ft³/PT/60gr ft³......Bulk purchase customers please contact us privately to apply for order discounts

Product Specifications

Picture Description and Specifications
The Diesel Oxidation Catalyst (DOC) is a device installed inthe engine exhaust line to convert carbon monoxide (CO)and hydrocarbons (HC) in the enginèexhaust into harmlesswater (H20) and carbon dioxide (CO2) through oxidationreactions.
  • Measurement accuracy: ±0.1
  • Operating temperature: 200–450°C

Formula:

2CO+O2--2CO2

CxHy+(x+4y)O2--xCO2+2yH2O

Metal DOC Catalyst vs. Ceramic: Stronger & Lighter

Metal substrate DOCs outperform ceramic with 3X better shock resistance, 50% faster light-off, and 30% weight reduction. Ideal for tough diesel conditions requiring durability and efficiency.

Fast facts 

1.Converts carbon monoxide (CO) into carbon dioxide (CO2) and water

2.Can eliminate muffler requirement

3.Harmful particulates are oxidised into harmless products

What are the strengths of our solution?

Our DOCs provide a simple solution for original equipment manufacturers (OEMs). They’re easy to install and maintain and don’t require any additional control from the machine operator. In many cases, the need for a muffler can be eliminated, and our DOCs can also allow for a wider ratings envelope. Concentrations of NO and NO2 can be optimised in the exhaust stream, and if your engine has SCR, this will make it more efficient and reduce diesel exhaust fluid (DEF) consumption requirements. Using a DOC also enables additional passive regeneration in DPF systems.

Chewing pups love them.
My 8 mo Morkie loves them . The other two won't touch them . They're heavier than I expected but Belle doesn't seem to mind that. Great for dogs that like to chew!

Meh..., I'll stick to fave pig ear chews
Only 4 for $6, idk these don't last long. I wanted to try them because my dogs love being spoiled but I think I'll stick to pig ears at a discount from Petco. They are very hard, some chews crumble or soften as the dogs knaw at them during the day. However these chews didn't last longer than 10 minutes compared to actual no rawhide alternatives I have used. These didn't do that. No upset stomach so that's a plus. The smell was similar to pig ears also, texture was different. No slimy residue w/ it unlike with the regular 100% pig ears. Helped with plague build up but there is still plague on insicor tooth. Probably won't buy again, meh.
