What is Diesel Oxidation Catalyst (DOC)

A diesel oxidation catalyst (DOC) is an aftertreatment component that is designed to convert carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water. 

It doesn’t matter if you are running your diesel engine on the road or off, you must still adhere to strict emissions standards. A diesel oxidation catalyst (DOC) is an aftertreatment device that can help you do that, as it effectively turns CO and hydrocarbons into CO2 and water vapour.

The DOC is part of the technology we offer to assist you in meeting Stage IV and Tier 4 Interim/Final emissions standards. It breaks down pollutants in the exhaust stream from a diesel engine, helping to reduce particulate matter (PM). It’s similar to a catalytic converter in a car.

Both carbon monoxide and hydrocarbons are converted in the DOC to carbon dioxide and water vapour. Exhaust gases are optimised so that they can perform in other systems in the aftertreatment, such as the selective catalytic reduction (SCR) or diesel particulate filter (DPF).

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.

Comfortable
Size: 9, Color: Black/Ivory
Most comfortable and roomy shoes I ever wore. Great for insoles. Looks nice too. The base of the shoe is a bit too thick but it’s fine.

Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again. If you find your right zie, they are really nice shoes at a very reasonable price for the quality.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable. They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace. Gets or picks up dirt a bit, but cleans well, except the canvas part. Has lasted almost 6-8 months with very little signs of wear. Feels very secure in any type of weather or condition. Great alternative or addition to having a pair of Stan Smiths.
