The controller in an Intelligent Ignition System charges and discharges the capacitor once across multiple crankshaft degrees.

• A. True
• B. False
• C. Not Sure
• D. Depends on the model

Answer: (B)

In an Intelligent Ignition System that uses a capacitor-discharge approach, energy is stored in the capacitor during a controlled dwell period and then released in a sharp, rapid pulse to create the spark. The timing is set so the spark occurs at the desired crank angle, but that discharge happens very quickly—essentially at a single moment in time—rather than lingering across many crankshaft degrees. So the capacitor is charged and then discharged in one brief event per ignition, not over a broad span of crank angles. That’s why the statement is not correct.
