EGR valves in engines

[RHFW]

I hear on the grapevine that people are removing egr valves and associated parts, remapping the engines system and getting more power more torque and have done away with a troublesome component of the modern diesel engine - mainly JD engines, I suspect

Does anyone have any comments, experience or criticism of the idea

Not EGR, but like many, I have had the DPF removed and the ECU remapped on my Kubota. Not for more power, but to deal with constant Regens. Cured the issues, and made the tractor easier to start as well... I could have got more oomph, but not what I wanted.

Essentially because Kubota put out a crap bit of kit...

Did this to my now 20 year old Ssangyong Musso with MB 2.9 engine. It’s a very well known tweak to install a blanking plate on the EGR and it makes engines run so much better as they are not trying to digest their own exhaust gases. The EGR tends to make the inlet manifold fill up with sooty crud which doesn’t do too much for smooth running.

I’d just hasten advice to get someone who knows what they are doing if in anyway unsure. Neighbour had a go at his and his JD turbo ate the blanking plate after it burst.

Just one of many traumas inflicted upon that poor tractor.

Don’t all JDs inflict trauma upon themselves

As a owner of three of them, i can clarify that it is not if they do, but when, and how expensive this time…..

Yes that is possible. It is illegal as the tier requirements are no longer complied with. It gives the engine clean cool air to run on, so less soot in the intake and less strain on the cooling system. Also less parts to go wrong.
On the downside it needs reprograming to work as it should, and that means letting someone hook up a laptop to your tractor that you have no idea about what they are doing and it is quite easy to make more harm than good - don’t ask where i heard that.
Don’t do it to save money!

Where've you been the last 10yrs?

We had trouble with the EGR on a JD 6630 a few years back. Called Derv Doctor. Sent him the computer thingy off the top of the engine under the bonnet. He returned it over night, remapped, together with a blanking plate and good instructions. He also remapped it to output close to a 6930. 5 minutes later it was all in place and has gone like a train ever since. Better on juice, loads more power and I'm happy that it's sucking clean air through and not exhaust fumes.

I've always likened EGR to having a tube connecting your arse to your mouth. You wouldn't like it, neither does your engine.

JD 6630, best £500 I have spent. Hardly have to change gear on the road.

If the argument for egr is "it is better for the environment" there has to be an argument that removing it is better for the environment just as much. Less parts to manufacture if it fails, higher life expectency for the engine etc.

I have an old seat inca as a farm runaround, does about 10 k km a year. I get a €10 or so surcharge every quarter because it is an old diesel. How is it better to buy a brand new spanker instead of using up old stuff?

Cos we know a lot of the "environmental" stuff is a tax raising exercise only...

Transforms them doesnt it

Do you get a big intake of breath and a shake of the head in disapproval from Main Dealers though?

 

[Gerbert]

Are there jd dealers that disaprove? Dealer here does them all the time.

 

[Tractor Tim]

08 fendt 718 egr valve fell to bits so set about replacing it to find a blanking plate had been installed before the engine was painted

No, why would they ?

Some modern stuff is better off keeping its egr in working order as it helps to bring down combustion temps during hard work.

 

[Wellytrack]

Well setup and sorted 6930 is an absolute powerhouse. 200 horse, 50k. Fairly compact. Still not many modern tractors would better one.

Yes, if start of injection is abnormally over retarded.
