METHOD AND DEVICE FOR OPERATING AN INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: A system and method for operating an internal combustion engine are provided to prevent surging as the mass flow of air flowing into cylinders is reduced through correspondent gradational or sequential closing. CONSTITUTION: A method for operating an internal combustion engine comprises following steps. Whether or not changes in target driving torque, which influences the unstable operation of a compressor(62) in an air-guided operation mode are required is inspected. If the changes in the target driving torque are required, the internal combustion engine is operated in a fuel-guided operation mode.
