Diesel Particulate Filter Retrofit on Construction Equipment

An example of an emissions control system using a CleanAIR PERMIT diesel particulate filter installed on a wheel loader in Torreon, Mexico to eliminate black smoke and odors from the exhaust. Notice that there is no dirty black smoke coming from the exhaust filter located on top of the vehicle even though the wheel loader is running at full load. The PERMIT Filter reduces particulate matter, carbon monoxide, and hydrocarbons from diesel emissions when installed on vehicles and stationary engines.

Great product. I could see this being really popular with fire departments and possibly not needing a exhaust hose system for their fire houses. There is a company, Ward Diesel Filter Systems, with a similar product. Should be standard on all new large machinery such as dozers, locomotives, and buses standard, would be if i had my way.

You are right! Ward Diesel incorporates CleanAIR's customized catalyzed particulate filter within their specially designed filtration system to get rid of soot, etc. from the exhaust of fire fighting vehicles. Technology is progressing to enable all large diesel machinery to make use of air pollution control equipment. Right now, many factors need to be taken into consideration when determining if a filter will work on a particulare engine, such as age, size, load, and exhaust temp.

how much horsepower do you lose? if its significant you'll need to burn more fuel, just a thought.

[CleanAIRSystemsInc]

A loss in horsepower is due to a build-up in back pressure. If a diesel particulate filter is properly sized for the engine type, back pressure is not an issue, therefore there is no loss in horsepower and no additional fuel burned.

mmm, now i can inhale diesel exhaust worry free

Obviously not. But a diesel particulate filter will remove over 85% of particulate matter, and 99% of hydrocarbons and carbon monoxide. As long as you have big rig trucks hauling goods and backup generators for power generation (which are necessary for today's economy) you'll have exhaust to deal with. Why not make it as clean as possible?

And one last comment: If burned without additives, pure Biodiesel (B100) is estimated to produce about 10% more NOx emissions than regular diesel. Debate continues over NOx, particulates, smog, and greenhouse gas emissions from biodiesel and all other new transportation fuels, biofuels in particular.

Here are two more diesel statistic: 1. A new 2007 diesel truck emits 1/60th the soot exhaust of a diesel truck produced in 1988.

2. In Southern California, trains emit about 111 tons per day of diesel particle pollution, or about 6 percent of the pollution from cargo transport in this region.

[CleanAIRSystemsInc]

The EPA estimates that this year, due to a combination of cleaner diesel fuel and new engine technology, SOx emissions from heavy-duty trucks will decrease by more than 100,000 tons and carbon monoxide emissions by more than 70,000 tons. The most significant benefits of clean diesel will be realized when new trucks are mostly replaced by 2020. By then, the EPA predicts two million tons of NOx and 83,000 tons of particulate will NOT be released into the atmosphere thanks to clean diesel.

There is actually more particulate in gas exhaust than diesel, but the primary pollutant of diesel, is the carbon particulant.

I suppose one thing about the DPF is that you no longer are required to muffle the exhaust, because the dpf does it for you. I personally run biodiesel in my truck, in which, when I smoke, I am blowing plant carbon back into the air, which does NOT add to the pollution, as that carbon returns to plant matter.
