07.1-010 Function injection system

L. Governor impulse method (RIV)

In order to be able to register the relationship of the injection pump relative to the engine two signals are required:

 TDC impulse from the crankshaft

 Governor impulse from the injection pump

Both impulses are supplied by pulse generators. In order to obtain a measuring signal the sensor pins must be moved past the pulse generators with a minimum speed (idle speed). A measuring instrument measures the time interval of the two impulses, converting the result into an angular value which is then indicated.
