Performances > Functions
Engine Governing, Engine Control
- All speed PID-governor
- Idle/maximum speed governor
- Torque based control structure
- Stability maps
- Droop = f (engine speed)
- Set speed ramps = f (engine speed)
- Torque limitation = f (engine speed, boost pressure, ...)
- Temporary excess power = f (time duration)
- Power reduction = f (coolant-, oil- , boost air temperature, ...)
- Start/Stop-procedure with coldstart control
- Charge air pressure control with variable turbine geometry VTG
- Control of exhaust gas recirculation, particle filter, catalyst
- Control of swirl flaps, waste gate
- More functions, especially application specific functions for marine, rail traction, heavy vehicle and aggregate on demand
Engine Monitoring, Engine Protection
- Monitoring of:
- Temperature, pressure, level of Intake air -, coolant -, lube oil - circuits
- Cylinder exhaust gas temperature
- Crancshaft bearing temperature
- Turbocharger speed
- Splash oil temperature
- Pre-alarm and alarm in case of limit value exceed
- Power reduction or engine stop in critical conditions
Injection
- Common rail – injection system, maximal 20 cylinders
- Configurable crank angle measurement
- Injection duration = f (injection quantity, rail pressure)
- Injection beginn = f (injection quantity, engine speed, ...)
- Rail pressure = f (injection quantity, engine speed, ...)
- Rail pressure PID-governor with suction throttle control and/or pressure relief valve
- Pre-injection, post-injection, multiple injection
- Cylinder specific injection begin and injection quantity calibration
- Automatic cylinder balancing
CAN-Communication
- Communication with Application Program on PC for commissioning, operation, adjustment and diagnosis, protocol: ASAM-CCP (CAN Calibration Protocol)
- Communication with higher systems via customer specific or standard protocols: SAE J1939, CANopen, …
- Redundant CAN-bus
Diagnosis
- On-line control unit self tests: monitoring of internal power supplies, sensor references, unit temperature and battery voltage; watchdog; memory tests for RAM, EEPROM, FEPROM
- Sensor, actuator, injector monitoring
- Error memory, error counter
- On board diagnosis OBD
