Ignition System: Description and Operation


System Schematic:






The Electronic Ignition System consists of a Single Board Engine Controller (SBEC), distributor, Crankshaft Position Sensor (CPS), distributor, and ignition coil. Proper spark advance is fully automatic, and is provided by a load table built into the SBEC. The SBEC also monitors signals from the Coolant Temperature Sensor (CTS), engine rpm, Manifold Air Temperature (MAT) Sensor, Throttle Position Sensor (TPS), and Manifold Absolute Pressure (MAP) Sensor when determining the correct ignition advance.
