Ford & IH finalize diesel divorce

[WilliamBos]

You said a mouth full there.. The EPA dont care becuase they dont drive a diesel or work in fields most of us do.. I cant figure out how much its saving on the air because it all gets traped in the filter right and then gets burned off in the air so its still going to the same place.. they should just take that DPF out of there and put another cat on there and forget about it.

A DPF and a Cat do 2 entirely different jobs. So that won't work.

Removal of the DPF is probably rather simple. After the DPF has been removed what has been accomplished? Who reprograms the computer? How is the metering pump disabled to prevent the introduction of fuel into the exhaust system?

The informatiuon below was taken from an article explaining how DPF works.

Regeneration is the process of removing the accumulated soot from the filter. This is done either passively (by adding a catalyst to the filter) or actively. On-board active filter management can use a variety of strategies:

Engine management to increase exhaust temperature
Use of a fuel borne catalyst to reduce soot burn-out temperature
A fuel burner to increase the exhaust temperature
A catalytic oxidizer to increase the exhaust temperature, with after injection (HC-Doser)
Resistive heating coils to increase the exhaust temperature
Microwave energy to increase the particulate temperature
All on-board active systems use extra fuel, whether through burning to heat the DPF, or providing extra power to the DPF's electrical system, although the use of a fuel borne catalyst reduces the energy required very significantly. Typically a computer monitors one or more sensors that measure back pressure and/or temperature, and based on pre-programmed set points the computer makes decisions on when to activate the regeneration cycle. The additional fuel can be supplied by a metering pump. Running the cycle too often while keeping the back pressure in the exhaust system low will use extra fuel. The reverse runs risk of engine damage and/or uncontrolled regeneration and possible DPF failure. Quality regeneration software is a necessity for longevity of the active DPF system.

I know that I think they should just add another cat to them and forget about the DPF it cost more then its worth.

Thats what the programers are for...

I'm with ya man, but just arbitrarily saying "add another cat" may not come close to the PPB level the EPA has mandated or else the auto companies would do just that.

I agree. Adding something that does not do the job is a waste of money. It does not solve the problem.

I agree! The best mileage I could get with my "emmissions friendly" Cat Acert is 5.3 mpg in my dump truck. A long way off from the 7 to 8 with the old mechanical motors.

My old boss has a '78 Volvo F89, beatifully restored. He used it to haul trailer frames to the galvanising company. His cousin had a brand new Scania Euro 4 , but the old Volvo used just half the fuel...

Taking it off was easy, 2hrs, and I'm no wizard.....

These guys, and they do it VERY WELL!!! For a small fee of course (~1100$).

Spartan Diesel Technologies - Technology Beyond Performance!

Almost doubled my mileage, and added ~ 250hp.

250 HP?

I'd like to see some proof of that from them before I'd buy one.

They do work, more fuel, but I would NEVER buy one. All the things you break will NOT be covered by warranty. GM now has the technology that once hooked up to their scanners that will show a tamper/programmer code.

NOT worth it.
