Ignition power module

IGNITION POWER MODULE

The power module, located on the side of the inlet manifold, is basically an electronic switch which, by means of the impulses coming from the control unit, controls the current in the ignition coil primary winding. Through a particular circuit it limits the current which circulates in the coil primary winding when the maximum value is reached in order to reduce the heating of the actual module.

To prevent the overheating of the coil if the ignition takes place with the engine switched off, the module has a rest closing device when the ignition impulses cease arriving from the control unit.

IGNITION COIL

The coil used is the closed magnetic circuit type with the windings in a plastic container immersed in epoxide resin.

The coil is connected directly to the spark plug by a silicon material extension which has high dielectric characteristics.

The earth for the secondary circuit is obtained with a special cable as the coil is insulated by the cylinder head.
