Magnetic flywheel Miniplane Top80 engine

The magneto flywheel also has a role of momentum wheel. Its principle is based on the storage and retrieval of kinetic energy. The physical characteristic is the moment of inertia which expresses the mass distribution about the axis.

The purpose of a magneto flywheel is to participate in the production of a spark at the spark plug. To consider the time required for combustion, which is very brief, it is necessary that this spark is caused just before the arrival of the piston at TDC (top dead center).

The access to the magneto flywheel of the engine Top80, allowing the removal and installation of the ignition coil is done by removing the fan assembly.
