Bernard Engines/Moteurs

Created in 1920 by Bernard, Bernard Motors whose main business was the manufacture of industrial and agricultural engines. They quickly gained a strong reputation for robust and high quality engines that where adopted by larger concerns looking for a high quality engine. In 1924 they formed an association with  “Guinard”,a manufacturer of pumps. In 1929 they squired C L Conord.

In 1934 Auguste Bernard sadly died, and his brother Frédêric took control as president with the support of Auguste son Jacques as a main board director. In 1941 Bernard Motors re purchased the thermal engines department from Ets. Japy Frères

In 1947 they produced there first air cooled light alloy engine, the W10. This was followed by many successful derivatives of this ally air cooled engine which powered the Energic motoculteurs of the mid 1950’s on wards. Notably the W110 (1951), W39 (1958), W139 (1961), and so on.

They where sold to the manufacturing giant  Renault in the early seventies (1972) and then de merged later.
