I got the new John Deere catalog, i was just skimming through when i saw an inline injector pump. so i stopped and looked at it.

here's what it says

SE500497 Bosch P Electric

9500 and 9600 combines
8560-8960 and 8570-8970 tractors

grand total 2200.00 bucks

here is what i found interesting, it looks a heck of alot similar to the p7100, on the back half there are some electronic which make me think it is electronicly govorned and the fuel is electronicly controlled.

Anyone know much about these pumps?
 
What do you want to know about them? Deere did in fact use electronically governed P7100s if that's what you're asking.
 
I was hoping the amount of fuel was electronicly controlled. if one could conjour up something to controll it it would make a 12 valve a whole lot more streetable.
 
Well, rack travel is controlled via the ECU, which is a given since there would be no other way to govern it. The Bosch ECU for the Deere apps is obviously an ag type governor which would probably not be terribly drivable.

Go take a look at the Bosch inline pump book. It gives you a general overview of the system. I don't recall if they had an automotive type electronic governor available or not.

My opinion is that it would be a waste of time developing what can already easily be done with the mechanical governors.

This pump is a P8500 13mm off a QST30 Cummins. The governor is a Bosch RE30. Its similar to a basic solenoid, but driven of a PWM voltage. The amount of duty cycle applied to the governor determines the rack position. There is a much better description and cutaway pics in the Bosch book.

BTW its the pump off the RH side of the engine.
 
i looked at buying that book a while back. looks like i have a real reason to buy the book now

The newer Cummins 30's use Bosch RP39's that are inline, electronically controlled and have dynamic timing.

You are correct. The pump I posted up is for an older G-drive engine, its driven with PCC3201 control. It uses a cut helix to advance timing at idle and light load. "Light Load Advance Pump" Cummins call it.
 
Ya i havent seen a Qst30 in a while...nothing like having a injection pump on both sides of the engine...last one i worked on was in a gen.
 
We used something similar to that in the Buhler Genesis tractors...MAJOR PITA for us...when we had trouble it was a real problem to diagnose where the issue was, because no one really knew anything about the system.

Actually its very similar to my current 8.3Ppump, but I have repalced the covernor and AFC from 160 hp pump.

Here is picture of my pump how they originally look. (Cummins 8.3 marine 450HP)

No, at the time i was reading some threads that were floating around that talked about a timing advance for the p-pump that is used on some of the bigger trucks.

What i was thinking is to Build/Design a computer to control it and make 12 valves a heck of alot better on the street. but that idea is not possible with this pump i guess. Judging from the responses.
