The Renault 70 hp or Type WB was a British V-8 aero engine that first ran circa 1913. The engine was manufactured by Renault Limited of West Brompton, London between August 1914 and December 1918, three other companies, including Rolls-Royce, also produced the engine. A variant known as the Type WC used an external oil pump as opposed to the internal pump of the Type WB. The Renault V-8 engines were noted as inefficient but reliable, the inefficiency being mainly due to the excessively rich fuel/air mixture used to assist cooling.
