In premixed charge compression ignition, the combustion chamber is divided into two and one is auto-ignited first. The other receives compression (rapid compression), which has a faster than piston compression, in addition to piston compression. Ignition timing prediction by Livengood-Wu integral was investigated by numerical simulation by changing the timing and strength of rapid compression. As a result, it was found that when the end gas part receives rapid compression before auto-ignition, the stronger the rapid compression, the smaller the Livengood-Wu integral value at the time of auto-ignition.
