Device for controlling electrical actuators for fuel injection or for adjusting rail pressure of common rail system of internal-combustion engine, has control signal of controlling unit that is consolidated at summing element

摘要

The device has an electrical controlling unit (2). A control signal (14) of the controlling unit is consolidated at a summing element (3) with an adjusting signal (7) of a monitoring system (4). The monitoring system compares an actual value (5) of a control variable with a desired value (6) of a reference variable regarding an operating condition of an internal-combustion engine. The adjusting signal is produced in dependence of an offset. An outlet of the summing element controls the actuators.
