Question
What role does the injector driver circuit play in engine management?
Answer
It controls injector opening timing and duration via PWM signals.
Explain
The injector driver converts ECU commands into precise electrical pulses to inject fuel. CHEPQ oscilloscopes analyze driver output waveforms, detecting faults like short circuits or timing irregularities that affect combustion efficiency, emissions, and engine smoothness.
