Abstract (en)
The invention relates to a hardware architecture of an ignition and/or injection managing system (1) for an internal combustion engine (2), of the type structured to cooperate with an electronic engine control unit (ECU) (3). The managing system comprises: a first module (4) structured to process electric signals from which the angular position of the engine driving shaft can be obtained; a second module (5) structured to process electric signals from which the cycle phase of the engine (2) can be obtained; a third module (6) structured to generate suitable signals for driving injector "drivers" (7) such that the injection profile stored inside the module is actuated; and a fourth module (13) enabling the third module (6) and receiving signals from the first (4) and second (5) modules and from the third module itself (6). <IMAGE>
