Internal combustion engine operation method involves adjusting default torque value such that no air-fuel enrichment takes place during economy-mode

摘要

The operation of internal combustion engine is controlled based on the default torque value, power value, load value or throttle valve position value. The default values are adjusted based on the switching status of a manual switch and the gear position, such that no air-fuel enrichment takes place during economy-mode. An Independent claim is also included for device for operating internal combustion engine.
