Fig. 1-12 Calculation of Ignition Advance Angle

(1) Main ignition advance angle

When  engine  water temperature returns to  normal,  generally, the  main ignition advance
angle  when  the  throttle  opens  is  the  minimum  ignition  angle  for  the  best  torque  point
(MBT) or the knock critical point (KBL). At idle speed, the ignition angle should be lower
than  MBT  point  for  idle  stability.  Provided  that  no  influence  on  cold-state  driving,  to
ignite  catalytic  converter  as  soon  as  possible,  during  the  heating  process  of  catalytic
converter, the basic ignition angle may not be the MBT or KBL ignition angle, and it may
be delayed as much as possible in the case of no influence on driving.

(2) Correction of ignition advance angle

Water temperature correction, intake air temperature correction, altitude compensation
correction, idle speed correction, acceleration correction, power enriched correction,
deceleration fuel cut-off correction, A/C control correction, and exhaust gas recirculation
correction.

(3) Acceleration correction

Ignition advance angle acceleration correction is to alleviate engine speed fluctuation
caused by drive system twist shock and eliminate knock shock that may take place during
acceleration to make acceleration process smooth.

(4) Power enriched correction

To get better power and torque, the air-fuel ratio will be enlarged to the best torque and the
