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.

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

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.

Very uncomfortable
Size: 7, Color: Brown Patent
Most uncomfortable shoes I own. The middle part is so hard and digs into your toes making it really painful. I wear a lot of heels and never have I had a pair that hurt this bad.

Foxxy Black Heel
Size: 6.5, Color: Black Patent
10/10 recommend. I love Steve Madden shoes. These were actually comfortable. I love the style and quality. The height was perfect for me. I was turning heads. The gold buckle and solid black made the heel pop!

Heel girly
Size: 8, Color: Burgundy Patent, Size: 8, Color: Burgundy Patent
The bottom is very slippery and you need cushions to go at the bottom of them. You have to be a real heel girly to walk in them, slightly comfortable.
