Abstract: A method and a device for controlling an internal combustion engine. An actuator serves to influence the quantity of exhaust gas recirculated. A loop controller preselects the quantity of exhaust gas to be recirculated on the basis of a setpoint and an actual value which characterizes the quantity of exhaust gas recirculated. A first measured value is determined in a first position (open) of the actuator, and a second measured value is determined in a second position (closed) of the actuator, with the actual value or a correction value being preselectable on the basis of the difference between the two measured values.

Abstract: An air/fuel mixture ratio learning control system for an internal combustion engine using a mixed fuel employs a learnt correction coefficient which is used both in a FEEDBACK mode air/fuel ratio control and in an OPEN LOOP mode air/fuel ratio control. The learnt correction coefficient is derived based on a FEEDBACK air/fuel ratio dependent correction coefficient per one of preselected engine driving ranges and per one of preselected concentration ranges of one fuel component contained in the mixed fuel. The learnt correction coefficient is cyclically derived in a preselected stable engine driving condition during the FEEDBACK mode air/fuel ratio control for updating a previously derived and stored one to minimize a deviation of the FEEDBACK correction coefficient from a reference value. The control system performs the FEEDBACK mode air/fuel ratio control with the FEEDBACK correction coefficient and the learnt correction coefficient, while the control system performs the OPEN LOOP mode air/fuel ratio control with the learnt correction coefficient.

Abstract: An apparatus for learning and controlling an air/fuel ratio in an engine having an air/fuel feedback control function wherein a fuel injection quantity Ti is computed by correcting a basic fuel injection quanity Tp by a feedback correction coefficient LAMBDA based on a detected air/ful ratio. Deviation of LAMBDA from a reference value during feedback control is determined to further determine a learning correction coefficient. Upon computation of Ti, Tp is corrected by a learning coefficient. A base air/fuel ratio obtained from Ti computed without correction by LAMBDA is made based on a desired air/fuel ratio. During feedback control, Ti is computed by further correcting the air/fuel ratio by LAMBDA. The learning correction coefficient is divided into an indiscriminate learning correction coefficient K.sub.ALT for learning deviation by the change of the air density with respect to all the areas of the engine driving state and an area-wise learning correction coefficient K.sub.MAP for learning the deviation by dispersion of a part for the respective area. Ti is computed according to Tp, LAMBDA, K.sub.ALT and K.sub.MAP. Where only the deviation by the change of the air density can be learned, the deviation is indiscriminately learned and K.sub.ALT is rewritten. In the other regions, the deviation by dispersion of a part is learned for the respective areas and K.sub.MAP is rewritten.
