Solved: Allemano's № 899 - 1954 Turner FWD prototype, coachwork by Whitson

Unfortunately I just have this image.  Google doesn't help in finding the diesel engine

[Allemano]

Wow! Thanks for the pic!

It's a very special Diesel engine. Locked for you to find at least some of the specs.

BTW: Google actually helps when you type in the right keywords. Maybe you have to ask what kind of Diesel it had...

[pguillem]

Hmmm, it doesn't look like steam or electric engine, Diesel was already established, Wankel not ready yet. That leaves for example a radial star engine.

It's not a radial engine, but one of those you mention.

Building on your answer to Wendax suggestion, I wonder if it could be a diesel-electric engine such as those used in locomotives.

No. It's a Diesel engine, but not many companies used it of that configuration. So, it's not kind of a hybrid powerplant.

Please unlock this puzzle, as I'm not any good in Diesel mechanics.  I'm sure that another puzzler will find the answer.

[Allemano]

I give you a point as you've provided the required details. Maybe someone else can give some more.

[Wendax]

It is the Turner FWD prototype shown at the 1954 London show, with Whitson minibus body.
Its Turner-built 1.4 litre Rootes-blown two-stroke twin-cylinder List diesel engine, 4-speed David Brown gearbox and hypoid axle were mounted as a quick detachable unit. Two years later, a 4x4 pickup with a three-cylinder List diesel engine was shown.

[Allemano]

And another point for Wendax!

[Hiawatha]

I'm sure Wendax meant Roots and not Rootes. I believe the 2 cylinder engine was called L40, whereas the 3 cylinder one was called L60. By the way, what does List mean?

[Allemano]

I read something that it was originally constructed by the Austrian Jenbach company.

[Wendax]

Roots! 

Professor Doctor Hans List founded AVL (Anstalt für Verbrennungskraftmaschinen List) in 1948 as an engineering bureau for his diesel engines.

[Wendax]

I read something that it was originally constructed by the Austrian Jenbach company.

List had just the engineering bureau AVL, no production facilities. The List diesel engines were built by Jenbacher and by Andritzer Maschinenfabrik in Graz.

There's a typo in the title - the coachbuilder's name should be Whitson. See replies #25 and #31 for confirmation.

[Allemano]

Thank you. Fixed.

Please help me with more information.
Can't find anything from this Turner company anywhere. They aren't the same as Turner Sports Cars. What was their full company name and address and their main products.

Thanks

[Wendax]

It was Turner's  Motor Manufacturing Co Ltd., Wolverhampton, building cars from 1911 to 1930, after an involvement in the Turner-Miesse and Seymour-Turner cars. After WW2 they were more into light delivery vehicles: http://www.autopuzzles.com/forum/index.php?topic=14954
