-We begin this chapter with the logotypes that were used by this brand in two different periods.
"Ader's logotypes"
-The 50 CV engine had four upright cylinders with a total displacement of 240 cu in.
"50 CV Adler engine"
-With a larger piston diameter the six cylinder engine gave 100 CV and the displacement was 514 cu. in.
"Ader V8"
-The eight-cylinder engine already had the V shape but using two crankshafts rotating in opposite direction and was connected by gears.
-It gave 222 CV at 2100 rpm and had a displacement of 826 cu in. The designation V was not entirely correct, actually they were two inline engines attached at an angle. Actually in U. It was known as U8.
-From appendix 9: A new view of the four cylinder 50 CV engine.
"The 50 CV Adler engine"
"The same Adler engine viewed from the other side"
"Adler Six cylinder inline engine"
-The Adler 6-cylinder engine had been designed for airships. The tube on the left goes towards the water cooling radiator.
From Appendix 10: We found new photos of the six-cylinder, in-line engine showing both sides, and a drawing of the same engine that has the water radiator added.
“Three Adler 6 cyl. images.”
-On both sides and the diagram has the radiator included.
