The Kinner B-5 was a popular American five-cylinder star engine for general aviation in the 1930s .
construction and development
The B-5 was a further development of the K-5 with slightly more power and larger dimensions. The biggest change was the extension of the bore from 108 mm to 117.5 mm with a resulting increase in displacement from 6.1 liters to 7.2 liters. In contrast to radial engines from other manufacturers, the B-5 had its own camshaft for each cylinder . This system was also used on the Soviet Schwezow M-11 . Most other radial engines, however, used some kind of "cam ring". The B-5 was a reliable running engine and was a thousand times in training aircraft of World War II installed. Its military designation was R-440.
