Gasoline injection and ignition system with DI, general
The gasoline injection and ignition system with direct injection in electrical combination with the sensors and actuators of engine 274 forms the engine management system.
Here the individual functions and systems of the engine management are controlled and coordinated by the ME-SFI [ME] control unit (N3/34).
The engine management is subdivided into the following systems:
- Base functions
- Engine system
- Fuel injection system
- Ignition system
- Exhaust regulation
Base functions
- Control unit diagnosis
- Fault memory
- EOBD II (EOBD II)
- Diagnosis
- Flash programming
- Variant coding
- Torque coordination
- Thermal management
- Alternator interface
- Synchronization
- Load determination
Using variant coding for example the following variants can be activated using XD:
- National version
- Transmission version
- Exhaust variants
Engine system
- Starter relay actuation
- Throttle valve control
- Safety fuel shutoff
- Transmission overload protection
- Driving on torque limitation
- Fan control
- Throttle valve calibration
- Adjustment of the intake camshaft and exhaust camshaft
- Controlling of the engine start/stop function
Fuel injection system
- Start, post-start phase and acceleration enrichment
- Warm-up control
- Cylinder-selective DI
- Fuel high pressure control
- Fuel pump controlling (fuel low pressure regulation)
- Idle speed control
- Limp-home function
- Rpm increase for an activated air conditioning system (with CODE HH4 (THERMOTRONIC automatic air conditioning) or with CODE HH9 (Semi-automatically controlled air conditioning system, TEMPMATIC))
- Deceleration fuel shutoff
- Altitude adaptation (integral pressure sensor in ME-SFI [ME] control unit (N3/34)
Ignition system
- single and multi-spark ignition
- Rpm limitation
- Knock control
- Synchronization of camshaft and crankshaft position
Exhaust regulation
- Catalytic converter heating
- Oxygen sensor heater controlling
- Straight-line lambda control
