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.

Hooked up 2 car amps. Works Great!!
Ordered up 2 of those under the car seat woofers with the built in amps. Installed this power distribution bus bar system, ran both amps through it and it works great. Super easy to install, holds up very well so far with solid connections, fits almost anywhere it’s not big, makes it easy to clean up the wires and make them look nice and neat, and it’s well worth the cost. Just remember if you do decide to hook up multiple amps or even just one that you are using the right size gauge wire, fuses, and the right terminals if needed. I saw that somebody melted theirs and I’m guessing it was not a clean install and probably had it fused and wired incorrectly. Overall super happy with the product, well worth the price, very durable, and I highly recommend it.

Clean and Safe Wiring
Installed this distribution block in my home car audio system and it works great. It helped organize my power wiring and made the setup look much cleaner. The connections feel secure and the fuse protection is a nice bonus. Check my videos to see the real setup and testing.
