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.

Parents of HS Students: READ THIS BOOK!
Format: Hardcover
A must-read book for parents navigating the "IVY OR BUST" aspirations of all top-performing high school students. Families simply can not afford the near-100K/year tuition for these institutions. It's unsustainable, and adding soul-crushing debt (before a career is even begun!) is not what parents want for our students. Enter Dream School: a guide to finding YOUR student's opportunity (and less expensive education) amid the noise and rah-rah of aggressive college recruiting. The book is a fast, comprehensive read which gives parents guidance and "permission" to consider schools with less name recognition/lower cost, but with high performance teaching and reasonable return on investment (ROI.) Remember the goal: a college degree for a happy, fulfilled student ready to enter the job market or grad school.

More than one way to a quality education
Format: Hardcover
As a high school counselor, I watch students and parents driving teens to the brink of exhaustion trying to get into the "right" school. I will not deny that there are some benefits to certain highly selective schools, but the issue is that very few do get in there, even if they are capable, and then what? Students think their future will not be as bright or that they will have fewer opportunities, and this book debunks that idea with research and sound principles. Finding a school that works with your strengths, your goals, and your budget is paramount today, and the very best way to create a future that brings fulfillment. Well-written and researched, this book should be reassurance for parents and students that there are many schools that can provide quality education and opportunities for our young people.

Permission to Help My Child Find Joy
Format: Hardcover
As a parent starting the college search process, I've really come to appreciate Jeff's insights in his previous books, podcast and newsletter. So pleased to finally have this book at my disposal, and less than a month in, it's already dog-eared and marked up! Like most parents out there, I'm fighting my own internal inertia to align my child's accomplishments against the "metrics" (real or imagined) of admission, and gravitating towards the big names. If you are in that stage, I'll say from personal experience that now is a great time to pick up this book. It's a quick read (for someone who's not a "reader"), and it plants the right questions and data in your head to open your perspective. Its funny, every good parent I know just wants their kid to be happy, to find their joy in life. When it comes down to it, our only equating of big name to their happiness comes a derivation that success brings happiness, and big school brings success. As Jeff suggests, this book doesn't say DON'T seek the big name... It just gives permission to look more broadly, that the same success, and perhaps even greater happiness, can be found elsewhere. Now we just need need to make sure our kids see that too, and they are empowered to seek their joy with our full support. There is still data in here that confirms name schools do convey certain advantages. Whether those advantages align with a child's success and happiness is the question we can chase in this process. I, for one, really appreciate Jeff's efforts to make the case for the broader search and taking the time to do it with excellent, fresh analysis of the data in hand. Maybe this book and others generate the momentum to continuing these unique data streams to break the US News/Naviance overload of the process. Good luck to everyone in a similar boat, and I hope you find this as useful a reference as I did.
