I got this off of today's Autotech Daily. Sounds like a mighty aggressive plan. Whether it ever makes it, is another story.<br><br><br>EPA TO CUT OFF-HIGHWAY DIESEL EMISSIONS BY 90%<br>A new proposal by the U.S. Environmental Protection Agency promises to significantly<br>reduce particulate matter and oxides of nitrogen emissions from diesel-powered off-high-way<br>vehicles. The rules, due to be phased in from 2008 to 2014, would affect some 1<br>million vehicles used for construction, farming and industrial applications.<br>The Engine Manufacturers Association calls the proposed rule &quot;very challenging&quot; but<br>promises to work with the EPA to meet the goal. Unlike diesels powerplants used for<br>passenger vehicles, the trade group points out, nonroad systems have more challenging<br>duty cycles, operate under harsher conditions, require a broader horsepower range and<br>are used in a wider variety of applications. It also notes that future U.S. regulations<br>should be harmonized with international standards as they are now because these types<br>of engines typically are used in multiple regions.<br>It says the key is the implementation of low-sulfur fuel. Under the EPA proposal,<br>sulfur content will be cut from the current 3,400 ppm to 500 ppm in 2007 and 15 ppm<br>by 2010. The lower level is mandated for on-highway vehicles starting in 2006.

we already run low sulphur diesel in our trucks ..........that's for off road built machines like tractors and mining trucks and such <br><br>

Saw this on the news last night.

We are already running this in our equipment( dozers, tractors, haul trucks, trackhoe.) We run highway fuel without the tax, we have a special permit to buy it that way.

I knew we're running low sulfur on the road, but I wonder how low it is? I'm betting it's no where near 15 ppm, but that's just a guess.

Ahh, just found my answer. See, that's what's good about these forums. It makes you think and dig a little. Presently, low sulfur diesel fuel is defined as that having a sulfur content of 0.05% total mass, or converting to ppm, 500 ppm, and that's a lot higher than 15ppm. Now, I wonder what effect 15ppm diesel fuel is going to be on our engines? I plan on running mine until at least 2006.

My bad, I wasn't paying attention to that.

Th engine manufacturers have already begun to address this because the environmental restrictions have been issued to the refining corporations to repair,rebuild or replace refineries that cannot meet this restriction by 2006-2008. Kyoto which Canada signed was asking for this by 2005, the US was smart enough to know that this will take longer but eventually will comply. The reality is cost of fossil fuel again will rise and the vehicles we use it in to comply. However the aftermarket additive boys are handed a new market to help older vehicles run on the lower sulphur fuels just like now. PK
