Ignition system (TC)

The ignition system is controlled by the ECU (1). The ignition is an integrated
digital electronic ignition system with static timing and advance using intermittent
sequential phased electronic injection feed. This ignition system is composed
of a crankshaft position (pick-up) sensor, an ECU, an ignition coil and an intake
manifold pressure sensor. The ignition coil is fed by the battery through a power
relay and is controlled by the ECU. Ignition timing is accurately determined based
on engine RPM and accelerator position.In addition to these key parameters,
inputs from the intake air temperature and pressure sensor and from the coolant
sensor are also used to control ignition timing.
