Bristol Draco
From Wikipedia, the free encyclopedia
The Bristol Draco was an air-cooled 9-Cylinder radial engine from the British manufacturer Bristol Aeroplane Company.
The Draco was tested with a fue;l injection system. The carburetor had only a simple butterfly valve, while two injection pumps supplied the cylinders with fuel: one handling four and one five cylinders - injection being into the manifold before they split into the two intake valves for each cylinder. The engine was flight tested in a Westland Wapiti. Since the expenditure did not bring considerable improvements the development was stopped.
