GF07.61-P-4010GA | Synchronizing fuel injection and firing order with incremental control function | 26.4.99 |
ENGINE 111.942 in MODEL 210.035 up to 30.6.95
P07.51-0501-05
Signal assignment engine 111
1 Crank angle
2 Cylinder ignition TDC
3 Signal of crankshaft position sensor (L5)
4 TNA engine speed signal
When the crankshaft rotates, an alternating voltage is generated in the crankshaft position sensor by the teeth of the driven plate. In this case, each tooth generates an alternating voltage signal.
-----------------------------------------------------------------------------------------
No voltage is generated as a result of the gap caused by two missing teeth. The engine control module detects the TDC position of cylinders 1 and 4 with the 2nd negative slope after the gap.
-----------------------------------------------------------------------------------------
Synchronization of the fuel injection and firing order is further processed by the engine control module for actuating the ignition coils and the fuel injectors.
-----------------------------------------------------------------------------------------
No camshaft Hall sensor is fitted to engine 111.942 up to 6/96. For this reason, the fuel injectors are actuated in pairs. 2 injection pulses are supplied for each power cycle (720° crank angle).
