Civic L4-1493cc 1.5L SOHC (VTEC) (1993)
Igniter: Description and Operation
Ignition Distributor Assembly
PURPOSE
Interrupts the current in the ignition coil primary windings, allowing stored energy to be released in the form of a high-tension pulse through the
secondary windings.
CONSTRUCTION
Molded resin body encasing an integrated electronic switching circuit with external electrical connectors.
OPERATION
Once the Engine Control Module (ECM) has computed a timing setting, based on the signals from the various sensors, the value is converted into
a control signal for the ignitor. When the signal again falls (to 0 Volts), the ignitor interrupts the current in the ignition coil primary windings,
allowing stored energy to be released in the form of a high-tension pulse through the secondary windings.
