Task
In order to facilitate starting of the engine when cold, additional fuel must be injected during engine start operation, depending on the coolant temperature. The increased quantity of fuel injected is achieved by extending the injection time.
Design/function
The start quantity control is dependent on:
- Start recognition
- Coolant temperature
- Engine speed
- Engine shutoff time
- Altitude on engine 137 and engine 112, 113 with ME 2.8
The start quantity control is enabled after start recognition. It continues to remain activated until a temperature-related engine speed is exceeded.
The higher the coolant temperature, the lower is the start quantity enable by the ME-SFI control unit.
