Ignition Lag or Delay Period:
It is the duration between the occurrence of the spark at the spark plug and the duration of the combustion curve from the motor curve. Factors influencing this phase are:
Nature of fuel
Mixture ratio
Initial temperature
Pressure
Temperature of the flame between the spark plug electrodes
