DEF FUEL ADDITIVE

[nitefarm]

I was wondering how the best way to store and transport the fuel additive to the field. Also what temp. does a freezing problem occur. I am putting a new service truck together and am going to have to start using it on this truck immediately and i talked to J. D. and they said they will require it in two yrs. Thanks in advance.

Require what, the DEF fluid?  Deere doesn't use it yet?

[nitefarm]

No not to my knowledge ,they said two yrs. ,also said thier engines would use only 2-3% def

Nite I believe your correct, my BIL is a JD man and he said he wanted to update tractors the last year that they didn't require it.

Deere will not use DEF until the T4 mandate which I believe starts in 2014.  CNH & Agco will continue to use only SCR but will use a lot more DEF to meet T4 requirements.  Deere will use both SGR & EGR which will reduce the amount of DEF needed.

To OP, DEF freezes at 11 degrees F.

I know what DEF is could someone educate me on SGR and ERG. I understand they are to help meet exhaust standards. But how do they work.

[Sid15]

Emission reg. is basically about reducing 2 things NOx & soot(PM)  In a SCR system because of high combustion temp there is less PM but more NOx & DEF breaks down the NOx into water & Nitrogen.  In EGR, a small amount of cooled exhaust is run back thru the engine to reduce combustion temp & thus reduce the amount of NOx created.  Because of the lower temp the PM does not burn up so a filter is used to trap it in the exhaust.  T4 requires a significant reduction in NOx, which Deere cannot achieve w/ out DEF.

I'm starting to think gas motors, in pickups anyway, may actually be more reliable. Have read articles about adding propane to older diesel motors. is anyone talking about using it to help with emissions. seems if it increases overall efficiency it would have to reduce Some emissions. Then what three "fuel" tanks on each tractor?!!!

I have a brother who is a truck driver and his semi has DEF. Said it uses about 1 gal DEF per 100 gallon of fuel. It has coolant circulating in the tank to prevent freezing. If it does freeze, once the truck warms it thaws back out. He has about 150k on it now, and there is no soot on the pipe at all. They are clean running. I have seen it packaged in 1 or 2.5 gallon jugs, mini bulks, or bulk at a fuel stop.

and once  a engine man. goes the scr def route like AGCO  has years and go and now finally CASE IH  has seen the light  you can remove the egr off the motor still meet teir 4 emmisions   get more power and better fuel efficenty,   

how much def you use depends on what your doing   harder you work it the more def  you burn    planting yeah 2 gal a day or less pull a big disk you could see it jump to 10 gal easy

every body is keeping it in mini bulk at there shops  not that big of the deal all the pickups have to have it anyway
