Device for control of internal combustion engines.

摘要

The present invention relates to a device for control of internal combustion engines, which comprises a first 3 and a second 6 precision units respectively receiving the signals sent by a position switch 1 and a crankshaft rotational speed converter 4. The two precision units 3, 6, connected together, are linked respectively by a first output to an analysis and reserve-maintaining unit 11 connected to the output logic 10 via a reserve channel 111. A second output of the second precision unit 6 is connected to a revolution counter 12 which is itself linked to a unit for determining the instantaneous mean value of the crankshaft rotational speed 13 which unit is linked with a permanent memory 9 and to the output logic 10, the inputs of the latter being connected to the output of the memory 9 and to that of a correction unit 14, while the input of the memory 9 receives the output signal from a discharge transformer 7. <IMAGE>
