Wolseley 60 hp

The Wolseley 60 hp or Type C was a British liquid-cooled V-8 aero engine that first ran in 1910, it was designed and built by Wolseley Motors. The engine featured water-cooled exhaust ports and employed a 20 lb (9 kg) flywheel. During an official four-hour test the engine produced an average of 55 horsepower (41 kW). A larger capacity variant known as the 80 hp or Type B used an internal camshaft and propeller reduction gear.
