Management of the ignition

MANAGEMENT OF THE IGNITION

The ignition management strategies are designed to strike the spark with the desired advance according to the engine operating conditions.

The management of the ignition basically consists of determining the ignition advance and implementing it through the operation of the power transistor incorporated in each coil. The "basic" advance value, calculated according to the intake air flow rate and the engine speed, is then corrected according to the different engine operating conditions. The control unit determines the start of the conduction of the current in the primary coil winding according to the engine rotation speed. This angle of this moment, obviously, varies in relation to TDC of the explosion stroke for each cylinder and the greater the engine rotation speed, the greater the advance, since the (dwell) time required to saturate the current in the coil primary winding is more or less constant. The moment of the start of conduction is corrected according to the battery voltage.
