M. Reference impulse verification (RIV)
Two signals are required for checking start of delivery when the engine is running (dynamic).
- TDC pulse from the crankshaft
- Reference impulse from the injection pump
Both pulses are supplied by pulse generators. To obtain a signal, the generator pins must be moved passing the pulse generators at a minimum rate (idling speed).
A measuring instrument measures the time gap of the two pulses and converts the result into an angular value, which is then indicated.
NOTE:
The position sensor can be used, as for naturally aspirated engines, for checking start of delivery when the engine is not running (stationary).
