Sd.Kfz.223 3.Serie and Sd.Kfz.222 4.Serie Horch 3.5 Litre V8 – Krümmer- Manifold - Part 1 - Inside Track | Renault TSF Tank Kent

This German terminology for the carburettor inlet manifold Krümmer (Zwischen Berg. u. Luftfilter) has been the source of much discussion and research here at the Foundation. We have encountered a number of these ‘Manifolds’ in our research. These include a large oversized take from the range of Horch cars of the period, a much smaller Solex fitting and a plethora of images from publications covering le.Pz.Sp.Wg. of the period such as the Type 801 Ersatzteil-Katalog Horch, the Type 801 Bedienungsvorschriften of Nov 1935, D664/6 Ersatzteilliste zum Fahrgestell and both period photos and drawings in D664/5 Gerätbeschreibung und Bedienungsanweisung dated 3 March 1943. The poor lead image is from D664/6. The combination of the grainy photos and drawings from the various manuals coupled together with the period Horch and Solex fittings set us on a course to construct an accurate reconstruction of these Krümmer (carburettor inlet manifolds). You can get a view of the complexity of the challenge from varying angles and dimensions of this inlet manifold from the images provided. The drawings to reproduce an accurate example are ongoing. The drawings are being done (as a wire frame) in 3D to allow for the device to be 3D printed in plastic to be analysed, proof fitted and changed as required. Once we have realised an accurate plastic example (i.e drawing) example we will commission the final 3D printing in aluminium. These Krümmer were only fitted to the Ausf.A armoured cars of 1. to 4.Serie inclusive, there is no survivor on the Sd.Kfz.223 4. Serie of the US Cavalry and Armor Collection at Fort Benning – lifting the bar of the challenge!!. Zwischen Berg. und Luftfilter (air filter). This device is fitted between the Berg.and air filter - the image provided shows it fitted to the top of the carburettor and the air filter. We have not yet made the air filter housings but have the filter segments in hand. Should any of you German speakers know what Berg. is an abbreviation for we would very much appreciate the insight!!. Until then have a wonderful Easter!!.
