This has been discesed on the http://vwdiesel.net/ forums quite a bit. One thing is the shape of the pre-chanber and size varances on the same head. We have also talked about making a insert to make the size of the pre-chamber. out put port and cost factors. Several people were working on this...

You are correct, except it shows something that can be done with a diesel EFI. That was my point, but as usual I get ahead of my typing, as compaired to what I am thinking *>)And that is rereading my post before posting
I think the cummings uses 5.
Thanks MS for your input.

Rudolph Diesel's first engines were run off coal dust. He finally went to a liquid fuel to fix some of the "running" problems of the engine. They may have worked it out. I will go read the paper next.

I was going to ask if you were running veggie fuel. Biodiesel is like diesel and doesnt need that BUT biodiesel is more comp;ated to make. I have heard of people using a glow plug to heat small fuel tank like a acuminlator used in gas VW's. I can not see how this would help the fuel in the...
The new Cummins engines in the Dodge trucks use a multi-squirt (pilot) injetion to quiet them down. The new "design" had to pass the "Wendys" test. That is where you can go to a fast food place, and order at the drive though and NOT have to shut the truck off. They could have made it quiter, but...

It is Probably a exercise in futility. I am one of those people that think there must be a way to do something. I hate to let some thing "beat me".
I have a diesel & automotive back ground as a Pontiac-GMC dealer mechanic, and then moving on to the big trucks. But when I almost starved...

The megasquirt is fine for gasoling setups that can use a batch system. It can be run with out some of those sensors but it doesn't matter as we are talking a diesel. I have used the megasquirt on several Gasoline(petrol) engines.
While I am sure their are tons of used parts, but...
It would be TD based. Most aftermarked FI uses PWM to control fuel delivery. I have built and Installed several Megsquirt (dyi) EFI units. These are not suitable because they are batch fire injection. Like a the old style VW Type3-4 ystem and 914
system,Djet, Ljet plus tons of euro cars.

I don't know. I think they both use the same too to lock the pump timing in place when doing some work on the engine, like replacing the head. I will have to check it out.
It is pre CRD, the pumps supply high pressure to the injecors. From whit I have heard A TDI pump can be converted to a pure...
TDI uses a sensor on # 3 injector for timing, = boost sensor, MAF, and normal GAS type sensors.
Fuel pressure not a problem. It is getting harder and harder to find good parts for thhese older diesels. Fuel Injection Pump are getting wore out that the good pump cores are hard to find. Junk...
I didnt make that clear.I am talking about the ECU. The Injectors would be in the same position in the head as before. IDI injection system with mechnical injection adapted to electronic. Aftermarket ECU's would be easy to use for this setup if the would work.
VW 4 cylinder IDI system like on...
What makes a Diesel EFI system more complex (accurate) than a Gas-Petrol EFI? I have been told that a gas EFI system doesn't provide the Accuracy required for a Diesel EFI.
I just don't see it.
Thanks

I found a good site with very good informatin and pipe-tube size, burst pressure, wall thickness, inside diameter. Using Barlows Formual:
theoretical bluging pressure= 2(yeld strenth)t/2
theoretical bursting pressure= 2(tensile strenth)t/d
t=Wall thickness
d=outside diameter.
I did not book...
