Continental O-470 family
Continental O-470 is a six-cylinder, horizontally opposed, air-cooled piston-engine family for general aviation. It is the carbureted branch of the 470 range; the related IO-470 uses continuous-flow fuel injection. The O-470 powered the Cessna 180 and early and mid-production Cessna 182 models. Its model-specific power ratings, compression ratios and installation details vary, so the broader 400-series specifications should not be treated as one exact O-470 configuration.
