Abstract
A homogeneous charge compression ignition internal combustion engine (HCCI) () is able to supply two types of fuels with different octane numbers to each cylinder () through fuel supply devices (). A controller () detects via an ion current sensor () disposed in each cylinder () a combustion timing corresponded state value having a regular correlativity to a combustion timing for each cylinder () and then adjusts by using the fuel supply devices () a relative proportion of a respective supplied quantity of each fuel to each cylinder () according to a deviation between the combustion timing corresponded state value and a desired state value set according to a working state of the HCCI engine. Thereby, it is able to efficiently inhibit variations on the combustion timing for each cylinder of the HCCI enginehaving plural cylinders without involving a complex mechanism.
