Internal combustion engine control device

The invention discloses an internal combustion engine control device. In an internal combustion engine control device (100), a control unit (107b) controls the operating state of an internal combustion engine (1) on the basis of a difference [delta]TCC between a first temperature TCC corresponding to the temperature of a first site in a wall portion defining a combustion chamber of the internal combustion engine (1), and a second temperature TE corresponding to the temperature of a second site in the wall portion, where said second site is further toward an outer wall surface than the first site. 在内燃机控制装置(100)中，控制部(107b)根据第1温度TCC与第2温度TE的差分ΔTCC，控制内燃机(1)的运转状态，第1温度TCC与内燃机(1)的划分出燃烧室的壁部中的第1部位的温度对应，第2温度TE与壁部中的相比于第1部位处于外壁面侧的第2部位的温度对应。
