Ford Motor Company specialists share tips for the care and feeding of your clean-diesel engine. (http://media.ford.com/article_display.cfm?article_id=24850&make_id=trust)

The Super Duty’s new 6.4-liter Powerstroke engine even offers increased power and torque making it the most popular choice for over 8,500 pound trucks, but these newer engines will require some special attention.

North America is on the cusp of a clean-diesel revolution, driven by the Environmental Protection Agency’s (EPA) mandated move to ultra-low sulfur diesel, which was launched Oct. 15.

Ultra-low sulfur diesel has a sulfur content of 15 parts per million (ppm), compared with low sulfur diesel at 500 ppm. Reducing the sulfur content will allow automotive manufacturers to build clean-diesel-powered cars and trucks that can meet the government’s stringent new emissions regulations.

“Removing the sulfur enables reduction of particulate matter by over 90 percent,” says Peter Misangyi, fuels and lubricants specialist for Ford Motor Company. “As a normal customer, you won’t see the telltale black smoke coming from the exhaust pipes anymore. In addition, NOx emissions are cut in half.”

In fact, the EPA estimates that by 2030, when the entire fleet (on and off highway) has been turned over, nitrogen oxide emissions will be reduced by 4 million tons yearly, and cancer-causing particulate matter will be reduced by 250,000 ton per year.

Ford Motor Company is leading the revolution, coming to market in early 2007 with the industry’s first clean-diesel truck engine in the new 2008 F-Series Super Duty. The Super Duty’s new 6.4-liter Power Stroke® engine even offers increased power and torque, making it the most popular choice for trucks that weigh more than 8,500 pounds, but these newer engines will require some special attention.

“The customer will have a new part to service, called the diesel particulate filter,” says Mike Harrison, 6.4-liter Power Stroke chief engineer, Ford North American Diesel. “But with proper use of the specified fuels and oils, typical servicing of the part should not be required before the vehicle has been driven 120,000 miles.”

The diesel particulate filter is an integral part of Ford’s clean-diesel technology. Working like a self-cleaning oven, the filter traps the particulate, or soot, inside the filter and regenerates itself, using injected diesel fuel to effectively burn and disintegrate the soot. Regeneration takes place about every 300 miles of normal use.

While older diesels should have no problem running on the new fuel, Harrison cautions against using anything other than ultra-low sulfur diesel in the new trucks. Any fuel containing more than the 15 ppm of sulfur could inhibit regeneration. Continued use of high-sulfur fuel may eventually clog the filter, calling for service at the dealer.

The EPA requires diesel pumps at filling stations to be properly labeled. Owners should read the labels carefully, as there are three: one for ultra-low sulfur diesel, one for low sulfur diesel and one for off-highway diesel.

Harrison also stresses the importance of reading the diesel supplement that comes with the vehicle owner’s manual. Here are a few other Ford recommendations to keep in mind:

Change the fuel filter at every other oil filter change. Oil filter change intervals have been extended to 10,000 miles from 7,500 miles under normal operation. Heavy-duty operation intervals stay at 5,000 miles.

Use CJ-4 oils, which minimize the amount of ash buildup in the diesel particulate filter.

Empty the water separator on the primary fuel-conditioning module once a month or when the warning light comes on. Failure to do so could cause corrosion of the internal fuel system components, leading to failure of the fuel pump and injection system. The water is considered a hazardous waste. The maintenance CD that comes with the vehicle provides information on the proper way to capture and dispose of the water.

The unique design of the Super Duty exhaust system prohibits the addition of chrome tip covers. An air infusion device entrains cold air into the exhaust to help cool it when the truck is in regeneration mode. It’s important to keep the openings clear of mud and debris.

Harrison suggests that when operating in hot climates or after a stint of high-speed driving, let the truck idle for about three minutes before shutting it off.

Sure!!!

Americans are going to do the extra maint. needed on this engine.. Sure they will.

Change the fuel filter every other oil change. Naw
Empty the water sepatator. I see folks scrathing the heads now over that one.
And no cutom exhaust system. Or chrome tips. HAHAHAHA!!!!

I just posed this to the diesel truck owners here at the office. There are two Dodges and a Ford out there. All laughed at the thought of the above mentioned changes in maint and exhaust stuff.

Not to mention Ford did a awful job with the current diesel offering. They have had nothing but problems with the current power stroke. Dodge on the other hand has been real stable with there Cummings.

This new power stoke should be fun to watch.

Hi Psy:

___We have never seen a domestic dump an ICE so fast as Ford did the 6.0L PowerStroke. 4 years cradle to grave almost sounds like something Honda would do! Although Honda does this it to improve upon the ICE’s capability, not because it was junk ;) The 03 and 04 Powerstroke’s were especially problematic. Ford was disabling the pre-injection just to get the darn things to run properly and even then there were a lot of buy backs as I remember reading over at Ford Truck Enthusiasts way back when. A friend of mine has an 05 F-250 w/ the 6.0 and so far, no problems. He even chipped the darn thing although that was not really a problem with the 6.0 … I was surprised that Ford stuck with IH when they could have simply went to Cummins and asked for their baddest monster and be done with all of this non-sense.

___And back to the point … Changing the fuel filter is something that should be done diligently as these new Piezo based injectors running at 15K + psi have extremely small orifices and anything getting through the fuel filters is going to create massive problems with these ultra expensive units. This will be the same with all Diesel’s as they attempt to match the new EPA specs with the higher injector pressures beyond the common rail.

___With a dummy light, emptying a water separator is not to big a deal. Custom exhaust might be a problem but I am wondering if Ford meant just the tips? An exhaust system with a DPF on it is not going to be able to be modded by anyone without some very advanced engineering behind said mods.

___My real concern was with the 3-minute idle time after a workout. I am wondering if this has to do with the DPF or if it is to cool the Turbo’s sleeves before taking her down? I thought Ford would have went to an electric oil pump for the turbo by now so the idle to key off time could be reduced to 0. I bet the Honda diesels will have this feature when they make it over in the sedans and such?

___Good Luck

Wayne the 3 min. idle time will be for the desoot to happen in the soot box. It sounds like to me its a super cat that will need to be high temp burnt once in a while. To break the soot down to a finer level if not gone all together. This also ties into the exhaust system that will air inject its self to help keep pipe temps down. Im sure this box will be down stream in the exhaust system so the intercooler or turbos wont be burnt up.

Hi Psy:

___Except we are talking at idle here. The extra outside combustion injection into a DPF or lean CAT to come should not be injecting into an exhaust stream while at idle. I do not see enough heat generation as was the case with the Insight’s NOx CAT. At idle, she always went into lean burn and stayed there until the next ICE-On light off. Not sure if this is the same with the new DPF’s but I bet it is from the write-ups I have read?

____The whole 3 minutes of idle in a hot climate or after high speed driving sounds like a turbo sleeve cool down cycle, not an emissions issue.

___Good Luck

Im sure your right. Trying to work and post really screwed me up. Let us not think about what I just sold cust. LOLOLOLOL
