Pkw Diesel als Schiffsdiesel umrüsten | Posts 80+

Hello buddy,

I'm not sure if I understood you correctly.
"Do you think it would be possible to operate the electric fuel injection pump without the engine control unit by replacing the electric actuator of the fuel injection pump with a mechanical adjustment, if such a thing exists? In other words, could the whole system function without any sensors?"

Hello,

That's exactly what I mean. You could certainly build something yourself there if you have the opportunity. The sectional drawing didn't seem entirely impossible to me, but I haven't taken a close look at it yet.
That's probably the cheapest option. The shut-off mechanism works electro-hydraulically, so I'm sure they'll find a fairly simple solution for that as well.

My offer, including the technical drawing, is still valid.

EDIT: Okay, I've looked at the whole thing again carefully. So, the modification should be quite easy to do. The electrical interlocking system is just a large motor that can rotate a maximum of 180°. I don't even think it needs that much range of motion. In short, this "motor" rotates another shaft, so you can safely remove it. At the end of the shaft is an eccentrically positioned pin that axially shifts another shaft, which has a groove where the pin engages. Therefore, it shouldn't be too difficult to attach a different shaft that can be operated via a cable and that also has two adjustable limit switches.

The only drawback is that you don't have a rev limiter, and the fuel injection isn't limited either. So, in a way, you can increase the power output beyond what's specified by simply pressing the accelerator more. But for such a low price, you have to accept some compromises.

Buddy.

That doesn't sound bad.
Building something isn't a big problem for me.
I can adjust the end stop while it's under load to a specific speed.
Could I potentially overload the motor by using a screw that is too large?
Or how am I supposed to imagine that?
I adjust the fuel injection amount using this built-in adjustment mechanism.
If he's getting too much diesel, wouldn't he just start producing black smoke?
or am I wrong?
Will the maximum power not be determined by the turbocharger's boost pressure and...?
Are the injection pump timings pre-set?
Without a load, I can definitely overspeed it; that's clear to me.

Hello Wolfgang,

Okay, I'm not really an expert on this topic. What I'm writing here is just what I know and my thoughts based on that. I don't know if it's necessarily correct.


Okay, I've thought about it again. I think if you modify it and then put it on a dynamometer, it should work. Then you can adjust the limiter settings so that the power output is correct. After that, you can choose the screw based on the desired performance.

Reversed, which isn't very precise, you adjust the engine based on RPM and power output, then set it so that it reaches its maximum speed at full throttle and allow for a little more. You never actually reach the maximum RPM anyway, and going beyond that point will make it easier to lose control.

I think I might have misidentified something earlier; it's just a shaft where the "motor" is attached. But you can actually install a different shaft there. You would just need to replace the cover and add a bushing and a seal on top. Then, it should work.

I'll try to finish it tomorrow, then you can see it and things will become clearer for you.

Greetings, buddy.

Hello,

The emails have been sent; there should be five of them.

I believe you also need to adjust the fuel injection timing during the ESP retrofit, or rather, set it to a fixed value, because the engine control unit (ECU) regulates it dynamically. The corresponding maps should be available for this.

The wastegate of the turbocharger will also need to be adjusted or replaced with a pressure relief valve.

With the data I sent you, you can take a look at it and then tell me what came of it .

Hello buddy,
Thank you, great thing.
Emails have arrived. I will get back to you.

I started a new topic here about this.
Okay, I'm ready. Please provide the German text you want me to translate into English.
