Circuit arrangement for short circuit monitoring

摘要

In a circuit arrangement for short circuit monitoring in conjunction with sequential triggering of injection valves of an internal combustion engine, one semiconductor switch being respectively connected in series with the coil of an injection valve and it being possible to control the semiconductor switches by control signals, provision is made in a line which is common to the coils of a current monitoring circuit which is connected on the output side to devices for switching off the control signals. <IMAGE>
