Gabriel Boucier designed an engine while he was still working in a company in England. He patented it, but it is not known if this engine has been built.
-It is a radial engine with fourteen cylinders in two rows. As we see by the cam plate detail, each cylinder has a single control. It has dual-lift cams: First exhaust and then another "push" and admission.
