Hirz made a water-cooled, upright inline-four engine. It gave 40 CV at 1,400 rpm.
-As we can see the construction of the Hilz was very similar to the car engines of the time.
“Hilz 50 CV”
-There were two more developments, with four cylinders as well, the 50 CV shown in the photograph, and another one that gave 60 CV. And there also were two fan-shape engines.
From Appendix 7: In the main text, this brand is mentioned as a 40, 50 and 60 CV engine construction company. It made another one with less power, between 24 and 30 CV.
"Hilz engine in Schulze monoplane" (PiP-fmr)
-Hilz Motorenfabrik was located in Dusseldorf. Around 1911-1913 it had two fan-type cylinder motors. (in the style of pioneer Anzani). Maybe they were built under license.
-They were the 25-30 CV with three cylinders, and the 50 CV with five cylinders.
"The 3-cylinder Hilz from the Schulze aircraft"
From Appendix 9: Below we show a new localized engine with 6 radial cylinders.
“Motor HilzStern, (Hilz Star)”
“Hilz inline-four engine”
-Above a new picture of the inline-4 that gave 65 CV, which complements those shown in the main text.
From Appendix 12: New drawing of a fan-shaped three-cylinder engine schematics.
