DEF question

[ajl]

So heres my question and im too lazy to search for the answer... if only we knew someone on agriville who did nothing other than post green energy and carbon tax info and articles every 9 minutes??

So had a neighbour delete his def on his big new holland 4wd 550 hp etc
And after the delete hes burning 0 def ( it was atrociously high prior to) but now hes burning 20 to 25% less fuel and has more power... so
although the exhaust is dirtier ..would it not be less harmful in the long run burning 20% less fuel?
My brain isnt exactly a rocket science computer but the math checks out.... does it not?

This is precisely why your not qualified for gubmint work. You simply don't understand the new math. You also need to understand that EV's are emissions free in order to be qualified.

Agree with everyone here. But.
Talked to the dealer manager whom I've known for 25 years.
Their outlet had ~100 combines operating in season. This year 10 had def related call outs. 9 of which were one trip, first day of use stuff. 1 unit was multiple callout.
Often maintenance related.
All repaired same day or next.
If you trade back to him you have to restore before it comes in.
Most buyers turned off by deletes.
Which I get. So many hp bumps sold along with. It's a $100k engine. Ask how they know this.
Can't imagine delete without exhaust system change. On this unit anyway.
So far, mine not a lemon. I'll keep the def for now.
Older daily use chore tractors I would do tho.

Someone has to do the math on these systems. The larger combines are getting more done per hour, so even with older style engines without all the emissions crap on them wouldn't be polluting as much anyway. Lower engine hours equals lower emissions. I just wish these guys with 8 years of post secondary education would focus on some simple math. A tractor , sprayer , combine at rest does not pollute. Lower hours with more done.

The newer machines use more fuel and with the addition of DEF create more emissions at the refinery stage where the public sees the emissions (mostly steam) .

If any of the crap they put on combines actually has made a significant difference , I would be surprised as my fuel usage is up plus adding DEF.

Its all quite stupid and why does anyone need a combine engine running hotter?

Article on CBC, low sulphur diesel reducing polluting oxides SO MUCH that the sun is increasing our temps faster? These green phuckers are making things WORSE!

It's hopeless. Less C02= cooler, till sun's heat is not reflected, then we get warmer?

I said all greenhouse gases, mainly water vapor, insulate and reflect.

This has much more to do with particulates and nitrous oxides…, CO 2 is not a direct health hazard like the other emissions which are reduced significantly… they cause cancer and lung damage.

SCR emission controls using DEF do nothing to decrease carbon emissions. On the contrary given that DEF needs to be produced and transported it is safe to say that using it increases CO2 emissions. Not that more of the gas of life is a bad thing but it does increase costs. Producing CO2 emissions never has and never will be free.

Oh chucky....C02 is NOT rising to insulate us, it sinks to the ground.
