The Renault 80 hp, or 8Ca, or Type WS is a development of the Renault 70 hpV-8 aero engine that was produced exclusively in the Unted Kingdom by Renault's British subsidiary, and its licensees, from 1913[1] to 1918.[2]
Apart from being physically larger, the only major design change between the 80 hp and the earlier 70 hp model was the use of articulated connecting rods. As a result corresponding cylinders in each row were arranged directly opposite.[3]
Valvetrain: Single overhead exhaust valve, single side inlet valve per cylinder.Although this valve arrangement is cited as "one side and one overhead valve," both valves are situated in a lateral pocket from/to which gases flow. Therefore both valves are "side valves" one on top of this lateral pocket and one on its bottom. There are no valves on the combustion chamber or on the overhead position.
Fuel system: Single 32 mm Claudel-Hobson carburettor
Reduction gear: 0.5:1, left hand tractor.(There is no proper "reduction gear". The reduction in this case is achieved due to the fact that the Airscrew is mounted on the Cam Shaft, therefore the shaft rotation speed, and so the airscrew, is half of the crank speed)
Performance
Power output: 80 hp (60 kW) at 1,800 rpm (takeoff power)
