N3/10 ME-SFI control unit

T1/1-
T1/8 Ignition coils, cylinder 1 to 8

Task

Reducing the thermal stresses on the engine at high temperatures.

Design/function

The ignition timing point is retarded by the ME-SFI control unit in line with the intake air temperature (charge air temperature in the case of supercharged engines) and "load" (engine speed and air mass).

The ignition timing point is retarded only if the engine is operating at a high load and begins from an intake air temperature of

approx. +35 °C and reaches its maximum at approx. +65 °C.

Example for full load:

35 °C (retarded 3.5° crank angle)

45 °C retarded 6.3° crank angle

65 °C (retarded 9.5° crank angle)

The following information is processed in the ME-SFI control unit:

Intake air temperature (charge air temperature in supercharged engines)

Engine speed/crankshaft position/ignition circuit detection

Throttle valve position

Air mass (boost pressure in supercharged engines).
