    The engine control module outputs ignition signals to the igniters after the basic ignition time has been calculated based on the engine conditions, and has been corrected according to the engine coolant temperature sensor signal.

  3. Engine Speed Control 

    An electronic throttle control system has been adopted, which conducts first idle speed control according to the engine coolant temperature and idle speed control after warm-up.
