RPM signal against Injector signal (petrol)

Volt division RPM: 10 Volts
Volt division Injector: 20 Volts
Time division: 5 mili seconds


As the we rev the engine up the amplitude and frequency of the RPM signal increases the dwell time of injector and frequency of the signal increases so it can provide right amount of fuel and at the right time inside the combustion chamber.
