The Kinner B-5 was a popular five cylinder American
radial engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is ca ...
for light general and sport aircraft of the 1930s.
Design and development
The B-5 was a development of the earlier K-5 with slightly greater power and dimensions. The main change was the increase in cylinder
bore from 108 mm (4.25 in) to 117 mm (4.625 in) and a corresponding increase in
displacement

camshaft
A camshaft is a shaft that contains a row of pointed cams, in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems ...
