Abstract
In the present spark ignition internal combustion engine, a shortest self-ignition delay time τmin for a maximum cylinder internal pressure Pmax and a maximum cylinder internal temperature Tmax when equivolume combustion is realized is calculated by using a calculation formula which uses a cylinder internal pressure and a cylinder internal temperature to calculate an self-ignition delay time, and a knock limit ignition timing ITA is determined based on the calculated shortest self-ignition delay time.
