Abstract
In an apparatus for controlling a Diesel engine with exhaust gas recirculation and intake air throttling a control circuit is provided by which the intake air flow pressure is controlled by means determining the desired intake air pressure for intake air throttling operation. During operations utilizing charge air the charge air pressure is controlled by means determining a desired intake air pressure representing the sum of a desired engine operating point-dependent base pressure value and a desired supplemental pressure value which comprises the product of a desired supplemental raw pressure value which is dependent on engine speed and a fresh intake air mass flow control difference and a factor which depends on the opening degree of the exhaust gas recirculation control number.
