om606 tractorpuller - appie - 07-20-2014
The ford tractor has a om606 with 7mm m pump, manifold made by me and a holset he451v as airpump..
It seems to burn the fuel cleanly. To bad the waterhose popt off, now the cooland comes out via a exhaust runner. Hopefully only a gasget....
What is the sharp noise running idle btw?...
Comments are welkom
RE: om606 tractorpuller - anjay - 07-20-2014
I assume that yours is in cloud of steam at the end of the ran. The noise when you release gas pedal is turbo surge. Basically engines rpm drops faster than boost and compressed air instead being inhaled by engine is escaping throw turbos compressor. Not really desireable but hard to overcome when you go from flat out fully loaded to idle.

Very cool. I pull tractors as well here in the States.
Sounds like it is running 6-7000rpm?
Is the class pretty much a "run whatever you brought" style of class?
It had everything from turbodiesels to V8's
RE: om606 tractorpuller - appie - 07-21-2014
hey.
The surge in am aware off, no big problem. I mean the short snappy high pitch sound when idlling...
As for the rules: 1400 kg max, 3.6 liter max. idd diesel intercooler and turbo, gasoline NA. the body has to be 25 years or older.
It's on youtube under deoldstock...
This tractor used to run a 3.6 audi v8, but i talked the owner un using diesel again
There is also a 1800 class, running duramax.......

I'm sorry guys, it's more easy to do technical talk in our language....
Bedoel je een nagelend geluid zoals in dit filmpje?
https://www.youtube.com/watch?v=bebYhuqfevE
Dat is redelijk normaal. Komt door je grotere brandstofpomp. Waar heb je de pomp laten bouwen? Of zelf gedaan? Het probleem is snellere injectietijd waardoor de zuiger te vroeg naar de andere kant van de cilinder word "geslagen". Dat knallen van de zuiger tegen de wand is een dieselklop. Normaal heb je een foefje (desaxatie) wat er voor zorgt dat je zuiger al aan de andere kant van de cilinder ligt, als de verbranding begint. Ik heb het met mijn zelfgebouwde pomp ook. Nagelt als een gek. Ik kan het alleen in jou video niet goed horen...
I'll try to translate...
You mean a nailing/knocking sound like in this video?
https://www.youtube.com/watch?v=bebYhuqfevE
That's fairly normal. It's because more fuel is injected. Where did you get your pump build? Or did you do it yourself? The problem is faster injection timing, causing the piston to hit the other side of the cilinder wall too early. The noise caused bij the slapping is referred as "diesel knock" (I don't know if it translates like that). Normally there's a little trick (desaxatie, don't know the translation) that makes the piston sit on the right side of the cilinder, before combustion begins. I've got the same thing with mij DIY pump. Knocking like crazy. I can't really hear it in the video you posted...

Hi Appie
what boost do you run?
exhaust back pressure?
temperature after intercooler and after turbo?
exhaust temperature?

Hey Tito.
The element are via van der kolk dpp, and build by a lokal..quistion is because cil5 is getting hotter than the olders... injectors a changed,pump check and ever iddle cc set back and still getting hotter than the older.
When the engine is up and running i'll try to check timing via a timinglight with diesel pickup..
The pump now gives 150cc... next winter we'll need more..
For the themps i'm sorry,the dataloger did not record, and i was personel ad vasteras
But boost is 2.7..
