Internal combustion engine operating method, involves activating electrical compressor during starting phase of internal combustion engine after predetermined time

摘要

The method involves activating an electrical compressor (5) during a starting phase of an internal combustion engine (1) after a predetermined time. The compressor is activated before increasing the speed of the engine and during a reheating phase of an exhaust gas processing device. The compressor is controlled based on heating power that is required for adjusting a predefined operation temperature of the device.
