-In 1907 they acquired the rights to build a 4 cylinder under license, but in 1909 they already presented what would be the initial line of V-8 engines, 40, 50 and 60 hp. Then it would continue to 75 and 100 CV.

-The model ENV F.A. 60 hp apparently similar to the Antoinette but with controlled intake and exhaust valves. It had casting cylinders and red copper outer jackets. Just as it can be seen in the illustration, with "L" chambers.

-Installed on the Voisin triplane from 1908-09 giving 50 CV. On the Sopwith Howard Wright a 60 HP engine. It was the so-called F model, a water-cooled V-8 engine. It was also installed on the Cody of the Michelin Cup.

-From 1910, ENVs are also built in the UK, by ENV Motor Co. in Willesden.

ENV, 100 HP
"ENV, 100 HP"

-We see a front section for the 100 hp, and the first thing that stands out is the overhead camshaft in the center of the V formed by the cylinders. This engine is from 1914

-The mechanical drive is done at the rear of the engine and on top of all is the magnet, driven by the same transmission.

-Although the following ad mentions "all-british", refer to this main text to see its French side.

-In several texts is insisted that E.N.V. means "En V" what would be possible on the French side, but doubtful. In English it would be "In V".

-Besides, as we see, after each letter there is a dot, typical of initials. We continue investigating.

From Appendix 6: After a recent visit from the collaborator of this vade mecum, Mr. JGB, to the transport museum of Lucerne in Switzerland, he gave us two photographs of an ENV engine mounted on an airplane.

In the first photo we can see the engine group mounted directly on the structure, without damping of any kind. A duct gathers the water outlets of each cylinder on one side of the V and leads it to its radiator. The other cylinder line has its own radiator on the other side.

-In 1909, at the Paris Air Show, this 40 hp ENV engine is presented, with the carburetor at the front between the V of the cylinders.

-And now we show the illustration of the ENV that appears in the main text in outline.

-We notice that the cylinders are more separated in the center, in pairs.

-Below the picture of a horizontally-opposed, four-cylinder engine as presented in another Paris Air Show. It gave 30 HP, and weighed 60 Kgs.

From Appendix 9: The V-8 of this brand, we can recognize it clearly in the museums through the red copper sleeves ("cuivre rouge" that surrounds the cylinders).

From Appendix 10: France / UK. In the aeronautical magazine "Flugsport" appeared a clearer photograph of the engine with four horizontally-opposed, water-cooled cylinders, which we bring here so that in a reissue it will be replaced in the main text.
