Mercedes 240 HP

Mercedes D.II

Deutsches Museum

Hans Trauner sends in this image of a Merceds DII from the Deutsches Museum collection, Munich.

Imperial War Museum, Duxford

Knut Erik Hagen took these photos in July 2003.

Dave Watts adds:
What's interesting is the Old Rhinebeck D.II engine. Upon examination it has a very well made specially converted or factory made D.III carburetor and intake manifold and there is a difference in the base flanges of the cylinders.

Rhinebeck

Mark Miller took these photos of a Mercedes engine at Rhinebeck in 1996.

And these photos are also of a Mercedes engine at Rhinebeck in 1989. This engine was on a workbench in one of the hangers and was obviously under repair. I believe this is the engine that was supposed to go in their Reproduction Albatros Dva. But, unfortunately, they could never get it to function properly.
notice the bracket on the port side toward the rear,. I believe this was to hold a generator.
I imagine it is obvious, but a lot of the stuff hanging on this engine is NOT stock equipment.

Mercedes D.III

The photos were taken by Tomasz Gronczewski and Karen Rychlewski in August, 2003, and each photo is marked with its owner's name. Each thumbnail on this page will take you to another page with more photos of the same features of the engine.

Mercedes D.III 180HP at the Trelour Annex

This incomplete Mercedes D.IIIa engine is part of the Australian War Memorial Museum collection at the Trelour Annex and is not on public display.

The engine has a number of suspicious parts, namely the: modern automotive type spark plugs, the short bolts fitted to the propellor drive flange and a few modern looking hose clamps.

Persons who have a copy of my book, "The Daimler Mercedes D.IIIa Aircraft Engine - A guide for modellers", should note the following:

My top view drawing of the inlet manifold is clearly not correct. My drawing shows an inner radius to the bends at each end of 6.5 mm, whereas the measured radius is about 15 mm. In consequence, the diameter of the inlet manifold pipe on my drawing may also be a bit too large.
My drawing of the flat top on the engine cylinder is not correct, it should be more oval, with the longer axis going through the valve springs.
The device that seals the water pipe joint between cylinders (see photo 'InterCyl WaterPipe Connector.jpg') looks convincingly original but is not quite what I had visualised from the source material when creating my drawings.

Persons wishing to view this engine should make arrangements as follows:

'The Treloar Annex is not open to the public, but access may be made available to serious researchers and veterans. For further information contact John White, Senior Curator for Military Technology on (02) 6243 4589 or by e-mail on john.white@awm.gov.au'
