New M-B A160 CDI CommonRail with DPF conversion in Germany

Postby jburke » Wed Jan 07, 2009 12:57 pm

You will find this interesting.
It's from the German owner of a new A160 CDI M-B with a DPF.

" The DPF after 9 months showed no usage restrictions, but I mussste the test with P oil at TÜV after the 5th Time break, because there is no soot picture was to recognize and therefore had to ASU with diesel made."

He designed his own control system and has been running for about 1 year w/o problems.
Here is the thread:

Plug the URL into Google translate set for German -> English

The owner also has a website with several PDF files describing the design in German.
I copied and pasted the text into Google translate too.

It's very difficult to understand. You'd have to be an electrical engineer to understand the controls.

I haven't found an overall description, but it seems that what he has attempted to do is to detect a low load situation and quickly and automatically switch to diesel after 140 seconds of no or light load. He defines low load as < 1000 rpm and the brake light is on always or 'a lot' Thats why he taps into the brakelight circuit, He taps into the alternator to determine engine speed. I think.

It's very encouraging to see someone trying to resolve the DPF and veggie oil problem. Hans Peter may have done it

Diesel Particle Filter.

aka Russe Filter, and RPF.

This thread is only of interest to those who have ( or will purchase ) vehicles that are equipped with DPF's, and attempt to run them on SVO, WVO or B100. Here in N.A., DPF's have only become common in 2008 and newer models

The basic problem is that the DPF gets plugged with soot and needs a regen cycle to literally burn the soot out. This involves delibaretly causing unburned fuel to go into the exhaust. Unburned B100 or SVO is expected to accumulate in the crankcase and lead to engine oil thickening and engine damage.

Hans Peter is apparantly attempting to solve the problem by avoiding plugging the DPF in the first place by not burning SVO when the engine is cold, during low load situations.

2007 is a transition year. One could have a 5.9l 07 Dodge or a 6.7l with the DPF.
