Chenu is an aircraft engine manufacturer that made its first engine from an automobile engine in 1902.

-It was a water-cooled engine with 4 cylinders grouped in twos, and gave 50 CV.

"Chenu 4-cylinder engine"

-This engine was mounted on the Lebaudy airship. In 1907 the "Ville de Paris" used a 70 CV Chenu, derived from a marine engine.

"Ville de Paris"

-The first Martinsyde aircraft were also fitted with the six-cylinder Chenu 90 CV.

As we can see, all of them were started with a crank handle.

"Chenu 6-cylinder"

-In 1910 they built 6-cylinder engines with cylinders in twos, like those used in the 4-cylinder engine, but giving 100 CV at 1,500 rpm.

"Chenu 80 CV"

-The next engine was also a 6-cylinder, but it had more displacement giving 200 CV at 1,200 rpm and it was designated AH-6.

-In 1913 they presented an engine that gave 50 CV at 1,300 rpm. The following year the same four-cylinder engine was rotating at 1,800 rpm giving 65 CV.

-In 1913 there was a 80 CV six-cylinder engine that evolved to 90 CV and 100 CV.

-The 80 CV version with gear rotated at 2,300 rpm.

-Below we present the 200 CV that is mentioned in the text. It is giving its power at 1,200 rpm. Later it delivered 250 CV while rotating at 1,500 rpm.

"Chenu 200 CV"

-The aviation engine that is not identified in UFEs (Unidentified Flying Engines) Ref. No. 16.

-The plane that is fitted with it is situated at the Museum of Brussels, in the Jubilee Park.

The Chenu at the MAE engine reserve stock has not a greater block but it does have some double cylinders of a comparatively large size.
