METHOD OF CONTROLLING THE OPERATING AN INTERNAL COMBUSTION ENGINE, AND A CONTROL SYSTEM FOR CONTROLLING THE OPERATION OF AN INTERNAL COMBUSTION ENGINE

摘要

Invention relates to method of controlling the operating an internal combustion engine (1), in which method combustion gas is pressurized by a first compressor (18) and introduced into the engine; fuel is combusted in the engine making use of the pressurized combustion gas thus forming exhaust gas; exhaust gas is removed from the engine; a portion of the exhaust gas is recirculated by including the portion into the combustion gas prior to its introduction into the engine; the portion of the exhaust gas is pressurized by a controllable second compressor (30) and introduced into the combustion gas; further a first signal (S1) indicative to the rotational speed of the first compressor (14) is acquired; a second signal (S2) indicative to the rotational speed of the second compressor (30) is acquired; feedback signal (F) is acquired as a function of the first signal and the second signal; and the feedback signal is used in process of providing a control signal (C) used for controlling the operation of the second compressor.
