The Continental O-520 is a six-cylinder, horizontally-opposed aircraft engine produced by [Vous devez être inscrit et connecté pour voir ce lien].

First run in 1963 as a development of the [Vous devez être inscrit et connecté pour voir ce lien], it has been produced in versions incorporating fuel injection (IO-520), turbo-charging (TSIO-520), and gearing (GTSIO-520).

Design and development


The IO-520 series of engines normally produced 285-310 HP and were used in numerous aircraft such as certain models of the [Vous devez être inscrit et connecté pour voir ce lien], the Beech Bonanza and Baron, and the Cessna 185, 206, 210, 310 and 400
series of aircraft.

It has largely been superseded by Continental's newer [Vous devez être inscrit et connecté pour voir ce lien] engine.

The IO-520 series of engine is considered to be a reliable engine, but some of the early versions of this engine had a weaker crankcase than subsequent versions.

Versions featuring more substantial crankcases are often referred to as having "heavy crankcases."

The GTSIO-520 was not as common and in its most common application (the [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] twin-engine aircraft) it produces 375 horsepower (280 kW).

The engine has a reputation of being expensive to maintain and is intolerant of improper pilot technique.

The intolerance is in the pilot going from cruise power to idle, reducing the tempurature of a working engine to an idle engine and causing cracks to develop on the cylinder head from the fast cooling.

More pilot planning is involved with this engine than the basic entry level engine because of the high tempuratures of the engine and the environment (low tempurature) that it is in.

When operated properly, most pilots consider the engine to be reliable.

Gearing reduces the RPM of the propeller making the engine quieter running than many other engines, although the gearboxes on early versions of this engine were notoriously unreliable.

The gearing also adds measurably to the overhauling costs of these engines.
