MONO - MOTRONIC INJECTION SYSTEM ( MA 1.7 )
The BOSCH MONO-MOTRONIC injection system is a (á, n) type, where:
á = angle indicating the position of the valve and reading the engine load.
n = engine rotation
These are the principle information for the electronic control unit (computer), used for
determining the basic injection time (t
the variation of the parameters with lent evolution: T engine, T suction air, lambda value
(ë), battery voltage.
The electronic control unit does the ignition advance calculation and the ignition coil
control for the MONO-MOTRONIC injection system, taking into account the evolution
of the parameters: T engine, T air, n (engine rotation).
The system is available and does not require adjustments. It is a self-adapting type
system, which corrects itself the parameters during the engine running, taking as well into
account its wearing during the run.
