August X. F. Michel, owner of a workshop on the Rue de l'Arsenal in Strasbourg, since 1923, reconditioned surplus engines after WWI.

-He made motors for canoes. And it is in 1928 when he built his first aviation engines: the 4-cylinder AM-5 with no more data than those that it gave 140 CV at 1,780 rpm and 110 CV at cruising speed with 1,500 rpm.

“AM-7”

-The AM-7 had six upright, inline, water-cooled cylinders giving 200 CV of power at 1,700 rpm.

"Another version of the AM-7"

-The AM-14 had 4 upright, inline, air-cooled cylinders with two initial series, the 14/1 of 80 CV and the 14/2 of up to 120 CV.

-The Michel AM-14 Series III, were also upright, inline, air-cooled 4-cylinders delivering 100/120 CV.

-They had a displacement of 7.4 liters, its cylinders measured 150 mm bore and 125 mm stroke.

-The power of the series III was 110 CV at 1,600 rpm and 124 CV at 1.680 rpm.

“An AM-14/2 at the MAE”

-It was followed by several AM-14: Series I, II and III.

“AM-14/1”

“AM-14/2”

“Michel AM-14/3”

-The Michel AM-16 was water cooled and gave 40 CV. This really modern looking engine with 6 cylinders is from 1930.

“AM-16”

-The AM-20 with the same technology provided 80 CV.

We have a new photograph of the water-cooled, inline, six-cylinder AM.16. It was made in three sizes or Types.

“Michel AM.16”

-Type I, gave 40 CV at 3,600 rpm.

-With a supercharger it went up to 75 CV at 5,000 rpm. Note the gearbox. It has a displacement of 61 cu. in.

-Type II, with 73 cu. in. of displacement gave 50 CV at 3,600 and 82 CV at 5,000 with supercharger.

-Type III, displaced 85 cu. in. giving 55 CV and 85 CV in the same conditions of the previous Types.

From Appendix 10: Manufactured at the Arsenal in Strasbourg, the A.M-7 (name derived from Aviation Michel) gave 218 CV at 1,750 rpm. It had two Zenith carburetors.
