Effect of the relation air to fuel and ignition timing advance
The correct management of the relation between air and fuel and the ignition timing
advance is the basis of the optimal functioning of the engine.
The ideal relation between air and fuel is the stechiometric relation in weight, which
determines the complete combustion
insufficient air or air in access will create a rich or lean mixture, which will influence
output and consumption as well as emissions in the exhaust. The electronic ignition
advanced control allows to optimize the performance of the engine, create maximum
output, reduce fuel consumption and polluting elements in the exhaust gas.
The electronic ignition advanced control integrated with the injection control, allows to
realize the best functioning of the engine in all conditions of its use ( starting at low-
temperature, phase of warming up, transitional phase of acceleration and deceleration,
engine in conditions of partial load, full load and idle speed)
