Continental IO-346 explained

The Continental IO-346 engine is a fuel-injected four-cylinder aircraft engine that was developed especially for the Beechcraft Musketeer Custom III by Continental Motors. It was produced for that aircraft between 1965 and 1969.[1]

Design and development

There is no carbureted version of the engine, which would have been designated O-346 and therefore the base model is the IO-346.[2]

The IO-346 was designed to run on 91-98 avgas. The engine has a dry weight of 269¾ lb or 297 lb including the generator and starter. The ignition system consists of dual magnetos, one Scintilla S4RN-201 and one S4RN-205 or, alternatively, two Slick Electro 449 magnetos.
