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
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
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.
