See also Hugon Gas Engine

Hugon was the manager of the Gaz Portatif Co (vendors of 'bottled' gas), and by c.1858 he had started experimenting with the expansive force of burning gas, leading to his work on the development of gas engines. Some time before 1865 he introduced a double-acting gas engine. It proved to be more economical than the earlier gas engine of Etienne Lenoir. His major contribution to IC engine technology was his incorporation of the trapped-flame ignition cock invented by William Barnett, which was more reliable than Lenoir's electrical ignition. Hugon also incorporated water injection for cooling and lubrication purposes.[1]

A double-acting Hugon vertical gas engine is on display at the Musee des Arts et Metiers.
