A method for operating a homogeneous charge compression ignition (HCCI) engine is disclosed. The method for operating an HCCI engine comprises: a step (a) of inputting an experimental value about the pressure rise rate of an engine in the operating range of an HCCI engine to an engine control unit; and a step (b) of switching from an HCCI combustion mode to a gasoline ignition operation mode when the pressure rise rate of the engine is at a predetermined level or higher. [Reference numerals] (AA,CC) No; (BB,DD) Yes; (S10) Inputting an experimental value about the pressure rise rate of an engine in the operating range of an HCCI engine; (S20) Engine pressure rise rate of a driving vehicle > 4bar?; (S30) Performing a gasoline ignition operation mode; (S40) Engine control; (S50) Average effective pressure of braking < 7bar ?; (S60) Performing an HCCI operating mode |
