Interesting pic, George.
That certainly looks like the Volvo logo on the gas cooler. Does anyone have an ID for this bus?
Cheers,
Max

Hi,

here a pic that shows the desolate situation of the Wehrmacht: a typical military truck of the Wehrmacht converted to a wood gas version:
Krupp L 3 H 163. Incredibly! (Source of the pic: an expired ebay auction).

Regards

Bert

A favour please.

Can anyone here positively identify the type of fuel system this Ford V3000S is using.

I think it is a type of Holzgas apparat and I identified it as being made by Imbert.

The original poster says it is not Holzgas and therefore not an Imbert unit.

Any positive Id would be appreciated.

The photo was taken in postwar Germany.

Hi Bill,
I'm curious what the OP posits this system is if not Holzgas? It appears that the visible components are typical of an Imbert type system albeit the cooler is somewhat larger than usual.
Cheers,
Max

If my eyes don't deceive me, there's pipework laid from the engine, over the roof and into (probably) the gasifier. Haven't seen that before in a lorry...some form of EGR maybe?

Markus

Edit: At least "Deutz-Generatoranlage für trockene Vergasung" for anthracite, coal, and brown coal fuels appears to have had an EGR line into the gasifier.

Hi Markus,
That's very interesting. This document has schematic diagrams of the major vehicle gasifier processes together for easy comparison: http://www.ebay.it/itm/HOLZVERGASER-HOL ... 1702547659 .

Max

The OP has now posted that it uses a coal fired steam engine................

I am researching that line but have found little so far.

Any ideas??

Coal fueled producer gas engine more likely. When I get home I'll try casting a locating spell for the schematics of that Deutz coal gas generator with EGR.

I think any suggestion of steam is very strange. Why, with steam production, would you need the enlarged radiator/gas temperature reducer?
For my money it is some form of word-gas producer, if not Imbert, then a similar contrivance,
Kerry.

Why,
For steam condenser, of course :wink:

Thanks for the input/help so far guys.

The OP belongs to a Forum that has an ID quiz section and he is not really familiar with military/commercial vehicles.

From what we can see on the rather poor image of the Ford, it does certainly seem to have all of the "classic" elements of a holzgas propulsion system.
I have loaded a diagram below of the Imbert system, and they all looked more or less the same.

We see the gas cooler in front of the radiator. As has been pointed out, it is very large compared to example photos of known holzgas apparatus.
I also do not see the two "lids" on the top that are always present on a holzgas cooler but that may just be the quality of the photo.

It also has the precipitating tank below the cooler. Here again, normally one or two pipes would be coming into/out of that area, one for incoming gas and one for the fuel going to the motor. I do not see these pipes.

It should have a large tank somewhere on the truck, the gasifier unit, and the only possibility I see here is what may be the shield apparatus for the unit behind the driver's cabin on the right side of the truck. The photo is so poor that I am not sure if this is part of a building behind the truck or part of the truck.

This vehicle also has additional cooling louvers at the top front of the motor hood that I have not seen before.

For the moment, I have a hard time believing this truck is running a steam engine as all other photos I have seen show the truck/s with one or two very large exhaust stacks for the excess steam to escape. I just do not see this on this vehicle.

I have been doing this kind of ID stuff long enough to know "Never say Never" and I won't do so here but it does not look like a steamer to me.

Hi again:

Sorry, Markus' and my posts were on top of each other.

Yes, the "cooling unit" as I described it could certainly be a steam condenser instead.

So, perhaps the mystery deepens.

But, but, the OP said the vehicle was coal powered and that should mean it needs all the other stuff too.

I will keep looking.

Bill

Here's a schema of a vehicular Deutz coal gas generator. Note the exhaust recirculation which might explain some of the Ford plumbing. Maybe most of the Ford generator parts were recycled from a bigger vehic; IIRC some Deutz generators came with gas coolers installed under the bonnet in large lorries.
