Abstract

An ECU (20), after the cranking is started, performs a control such that the first combustion cycle is executed on a CPS-equipped cylinder (step 100). After that, self-ignition occurs in the first combustion cycle, and the in-cylinder pressure changes. The ECU (20) detects change of the in-cylinder pressure by using a cylinder pressure sensor (22), and acquires the maximum value thereof as a value Pmax (step 102). Next, the acquired value Pmax is corrected on the basis of the engine coolant temperature or the amount of in-cylinder air (step 104). The ECU (20) pre-stores the relationship between the value Pmax and the octane number (RON) as a map. The ECU (20) determines the octane number (RON) that corresponds to the value Pmax, from the map (step 106).
