TRIONIC Ignition System

The Trionic system is a distributorless capacitive discharge type. Components include an ignition cartridge, Hall Effect sensor and knock sensor. Each spark plug has a separate coil. Energy for the spark is stored in a capacitor and discharged through the ignition coil upon a signal from the ECM.

When ignition is switched on, both main relay and fuel pump relay operate for a few seconds. As soon as ECM senses that crankshaft has begun to rotate, coolant temperature dependent fuel injection takes place through injectors simultaneously. This enables short starting times to be achieved. If engine is started and shortly afterward switched off again, a fresh pre-injection sequence will be obtained if 45 seconds is allowed to pass with ignition switched off.
