Engines from 1949 built by Marcel Echard (Moteurs Lutetia), specialized in 2-stroke.

-His 4.C.02 model was tested on a Baby-Jodel. They were air-cooled V-engines.

-It had 4 cylinders in V, double ignition and 1,267 cc of displacement. At the rear it had a supercharger.

-It had a manual starter, and gave 45 CV at 2,800 rpm.

-The carburetor is below the front, where there is a compressor.

-The engine has double ignition it and occurs in the two twin chambers at the same time.

-The given power was 70 CV at 2,600 rpm.

The author of this edition of Aeroengines AtoZ, through Aeroteca, collaborated on Version 2 of this video, which is presented here.

To understand the operation of the connecting rods, the 1929 Continental R 670 single-cylinder engine was chosen.

A demonstration of Version 3, improved at the author's suggestion, is also available on YouTube at a later date. This version shows bronze valve guides, improved valve spring movement, and the split crankshaft counterweights and front bearing balls also move.

The design is from Juan Soler, Sant Cugat, Barcelona

Below we show a flash of version 3
