A simple magneto (an electrical generator using permanent magnets) is able to produce relatively low voltage electricity, however it is unable to produce the high voltages required by a spark plug as used in most modern engines (aside from diesel engines). [2] An ignition magneto also includes an electrical transformer, [2] which converts the ...

The engines are all carburetor-equipped, feature dual magneto ignition and have a displacement of 233 cubic inches (3.82 L). The first O-235 model was certified on 11 February 1942. [2] The O-235 was developed into the lighter-weight Lycoming IO-233 engine for light sport aircraft. [3]
For redundancy, virtually all piston engine aircraft are fitted with two magneto systems, each supplying power to one of two spark plugs in each cylinder. Magnetos were used for specialized isolated power systems such as arc lamp systems or lighthouses , for which their simplicity was an advantage.
You can conduct experiments, and should test all major changes, in either this template's sandbox, the general template sandbox, or your user space before changing anything here. This template provides formatted output for piston engine (including all radial, inline, V-, and rotary engines) specifications per Wikipedia:WikiProject Aircraft ...
The Rotax 503 is piston ported with air-cooled cylinders and heads, utilizing either an engine driven fan and cowl, or free air cooling. Lubrication is either by use of pre-mixed fuel and oil or oil injection from an externally mounted oil tank. The 503 has dual independent breakerless, magneto capacitor-discharge ignition (CDI) systems.
To change this template's initial visibility, the |state= parameter may be used: {{Aircraft piston engine components | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Aircraft piston engine components | state = expanded}} will show the template expanded, i.e. fully visible.
While true dual ignition uses completely separate and redundant systems, some certified engines, such as the Lycoming O-320-H2AD use a single engine magneto drive-shaft turning two separate magnetos. Whilst saving weight, this creates a single point of failure in mechanical terms, that could cause both ignition systems to cease working.
