METHOD AND DEVICE FOR MODIFYING THE INTERVAL OF SUCCESSIVE IGNITION CONTROL PULSES DELIVERED BY AN IGNITION PULSE TRANSMITTER

摘要

A.PROCEDE FOR MODIFYING THE INTERVAL OF SUCCESSIVE IGNITION COMMAND PULSES DELIVERED BY AN IGNITION PULSE TRANSMITTER, PULSES WHOSE PHASE DIFFERENCE IS DETERMINED BY A FIRST PHASE COMPARISON DEVICE. /P P B.PROCEDE CHARACTERIZED IN THE CASE OF SHORTENING THE PHASE INTERVAL OF THE SUCCESSIVE PULSES, THE PHASE INTERVAL IS EXTENDED BY ADDITION OF A MAXIMUM VALUE OF PHASE DIFFERENCES OR BY THE MEASURED PHASE DIFFERENCE, TO THE EXTENT THAT IT IS SMALLER THAN A MAXIMUM PHASE DIFFERENCE. /P P C. THE INVENTION APPLIES IN PARTICULAR TO AUTOMOBILE ENGINES.
