Michel made a Cam type motor, but not like those known from Marchetti, Fairchild, Caminez or Canda.

-The Michel Cam Engine, patented in 1921, has the inner cams on a plate, as we see below.

“Patent Fig. 3”

-With three pistons, the cam itself is a channel in the plates on both sides as we can see in the following figure.

“The Michel engine horizontal cross-section”

-The Michel company was in Kiel (Germany). The engine was water cooled and it operated with the two-stroke cycle.

-The three pistons used a single central combustion chamber.

-Fuel (Diesel) was injected into this chamber.
