Place the operational stages of automotive spark generation in chronological order, starting from the low-voltage circuit supply to the final ignition event.
- 1Battery voltage energizes the primary coil winding to build a magnetic field.
- 2The ignition control module interrupts primary current to collapse the magnetic field.
- 3High voltage is induced into the secondary winding by mutual electromagnetic induction.
- 4High voltage surges to the spark plug and arcs across the electrode gap.
Cevap
The correct sequence begins with primary winding energization to build a magnetic field, followed by current interruption to collapse the field, mutual induction of high voltage in the secondary winding, and finally the spark plug electrode discharge.
Automotive ignition operation relies on electromagnetic induction. First, battery current flows through the primary winding to store magnetic energy. Next, the primary circuit is broken by the control module, causing the magnetic field to collapse instantly across the secondary winding. This collapse induces a high-voltage pulse of 20,000–50,000 volts, which travels to the spark plug and jumps the gap to initiate combustion.
Adım Adım Çözüm
Anahtar Kavram
Electromagnetic induction in ignition coils requires establishing a primary magnetic field and rapidly collapsing it to induce high secondary voltage.
