<p>A system comprising: a sensor (2) connected to a first ground (5) having a variable electric potential affected by the engine and electromagnetic fields, which sensor supplies a signal as a function of the amount of oxygen detected in the exhaust gas; a first block (6), connected to the first ground (5), for biasing the sensor (2) to a given voltage (+V1); a second block (18) for converting the signal from the first block (6) into a signal relative to a second ground (21) having a constant electric potential and isolated in relation to the first ground (5); an electronic control system (23), connected to the second ground (21), for processing signals relative to the operating conditions of the engine, and the signal from the second block (18); and a third block (24), enabled by the control system (23), for controlling regulation of the mixture strength. <IMAGE></p> |
