The Continental C75 and C85 engines were made by Continental Motors in the 1940s, both sharing the US military designation O-190. Of flat-4 configuration, the engines produced 75 hp (56 kW) or 85 hp (63 kW) respectively.[1]
The two engines shared the same bore, stroke and compression ratio. The C-85 produced ten extra horsepower by virtue of having a maximum permissible rpm of 2575 versus the 2275 of the C75.[1]
The C75 was in production from 1943 to 1952 and the C85 from 1944 to 1970.
