Why leave a diesel running while filling it up?

[racrguy]

They should have invested more wisely in emissions R&D. ACERT sucked and the technology that was required to meet 2010 on-highway regs (that most everyone says they lacked) will be required off highway (ie. dozers, graders, etc) in 2014. For their sake I hope they bailed bc of market conditions and not a lack of tech because if they don't have a solution by now life will really suck when Tier 4 Final regs take effect.

I work for Volvo CE and got a chance to look at some of the proto T4 machines. Holy fuck those things look like a bowl of 'sploded spaghetti with all the added emissions equipment. I feel sorry for the guys that have to put them together new, I pity the poor guy that has to work on them should the need arise.

some people just like the noise of a diesel. i agree though turn the damn thing off nobody wants to hear that pos run its nothing new. been driving some Benz power this year and they are great motors w plenty of boost

Here's a shot of just a portion of the exhaust aftertreatment on a 2010 on-highway power unit I developed (for workover rigs) that has DPF and SCR... you wouldn't believe how hard it is for some people.




And here's the other part here you can see some of the SCR electronics, DEF tank, dosing controller, supply module, etc. No matter what the application, everything new will have all of this just arranged differently.

LMFAO!
Believe it or not the world does not revolve around tractor-trailer rigs.
You think a 78% market share in a field as intense as oil and gas pressure pumping (ie. frac rigs, at $225,000 per engine) is just a fluke?

Next thing you'll hear, "don't know why they're not in a Ford...."

Good grief. How difficult was it to design and get it all working correctly?

I foresee a jump in used heavy equipment prices in the near future, semi's, off road equipment, everything that has a diesel engine. Are you seeing a loss of fuel efficiency any? I think if they did lose fuel efficiency that may be a bigger turnoff than the increased price that's sure to accompany all the new emissions regs.

Our "emissions solutions" group in Indiana handled the DPF and SCR component development, EPA cert, etc. It was my job to make it all work, fit, stay legal within the bounds of the EPA certs and be as user friendly as possible in this application. Starting with nothing but engine models and datasheets me and my design engineer (ProE expert) had that complete unit designed, built, dyno tested and in a rig in 12 weeks with a full wiring harness and control system.

And it beat the shit out of me mentally.

Actually on the industrial side we've seen up to a 6% increase in fuel efficiency from T3 to T4i. With external emission control stuff you don't have to try to solve every problem (NOx, CO, PM) in the cylinder. You can optimize part of it with piston and injector design and injection events and take care of the rest later with catalysts.

Ford owns Cummins. Duh.

YUP YUP!

This is why Ford and GM are schooling Dodge in the power and fuel mileage department with their latest offerings.

Cummins is going to have DEF in 2012. Hopefully we'll see the power and mileage increases too

[tribaltalon]

why would you want Cummins to have DEF? that shit is the biggest pain in the ass. I was so excited when I went from my POS Columbia to a brand new 2011 Volvo VN until i realized i'd have to deal with putting DEF in every time i fueled up. Luckily, I managed to switch to an 05 Volvo which doesnt have the DEF. So i can just fuel up, take a piss, and go instead of having to buy those damn blue boxes. and BTW, my truck idles nonstop (when i'm not driving) every day 5 days a week at least.

[dewayne6243]

Truth..... This man speaks it!

6.0's don't like anything below 50 degrees
7.3's can deal with high 30's and start fine
5.9 cummins 12v's, 24v's and cr's fire up at any temp with zero issues.

The three duramax powered trucks we have are a pain in the ass when temps drop around freezing.

When it was 7 degrees my 6.4 powerstroke started as fast as you could turn the key. I never wait for that light.

in a passenger vehicle that's just daily driving, DEF usage is far less than a fully loaded commercial application.

I modify all of my vehicles, so if I purchased a truck that used DEF, I would just delete all that shit anyhow

If I was to buy a new truck it would be a glider, pick up a well put together pre egr and roll it. Some of the big company's are starting to go this route. New truck with zero extra crap on it. CA is only state that sounds like there going to have issues in future. Let the bottom feeders company's go in and out for penny's per mile.
To bad you couldn't get pickups in a glider kit.

[gt freakk]

i thought it was because they wanted everyone to know they had a diesel...i keep my mustang running while i put gas in it...just so i can hear my system

I think that's why he didn't list the 6.4L. But yeah you're right, when we had the streak of all those cold days this past winter my truck started up just fine. A couple of times I waited till the light went off which took about 10 seconds. Then other mornings I just fired it right up. But then again my truck was fairly new then.

I would hope a common rail would start quickly. once Ford got rid of the POS Rube Goldberg HEUI bullshit, the trucks actually start and run well
