The control unit produces output signals whose length is dependent upon the input engine working analogous signals to alternately excite each magnetic injector valve fitted tin the intake pipes which belong to either a 'V' or a horizontally opposed internal combustion engine. Exhaust probes are also provided in each exhaust pipe and connected electrically to the emitter electrodes of two npn transistors whose collectors are joined to an additional control unit input. The transistor bases are connected by resistances to the outputs of bi-stable integrated circuit so that under working conditions one or the other transistor is always conductive in order to pass a signal to one of the oxygen probes. |
