Claim:
1. A heat release rate waveform generating device for a compression self-ignition internal combustion engine that carries out self-ignition combustion of fuel injected from a fuel injection valve into a cylinder, the heat release rate waveform generating device comprising: an electronic control unit configured to: (a) divide an inside of the cylinder into an internal region inside a cavity provided in a piston and an external region outside the cavity, (b) generate an ideal heat release rate waveform for at least one of the regions, the fuel injected from the fuel injection valve being present in the region, (c) generate the ideal heat release rate waveform for the internal region inside the cavity when the fuel injected from the fuel injection valve is present only in the internal region inside the cavity, (d) generate the ideal heat release rate waveform for the external region outside the cavity when the fuel injected from the fuel injection valve is present only in the external region outside the cavity, and (e) individually generate the ideal heat release rate waveform for each of the internal region inside the cavity and the external region outside the cavity when the fuel injected from the fuel injection valve is present in both the internal region inside the cavity and the external region outside the cavity.
