ABSTRACT:
An internal combustion engine controlling apparatus comprises an exhaust gas returning passage for adjustably returning a part of exhaust gas from an internal combustion engine, a calculating means for effecting digital calculation of a controlled quantity for the engine in response to operational conditions in the engine in accordance with a program, an oxygen sensor for detecting the concentration of oxygen in the intake air after recirculating the exhaust gas to the air intake system, and an operating means for operating the output of the oxygen sensor on the basis of data stored therein to thereby determine a controlled quantity for the engine to operate it at the optimum condition.
