The Steel Products Engineering Company of Ohio built aircraft engines in the mid-1920s, such as the “Rausie” E-6, a 6-cylinder in-line engine giving 175 HP at 1,650 rpm. See Rausenberger.

-In 1924 there were two engine projects, one was a Flat Twin and the other a radial.

-The horizontal twin-cylinder engine gave 20 HP at 3,000 rpm. Harold E. Morehouse was involved in the project, although he was already at Wright Aeronautical.

-The 5-cylinder radial engine was to deliver 95 HP at 2,000 rpm. We have no further information on this engine, but we are continuing our research.

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
