Nishida, M

An internal combustion engine controlling apparatus is described which comprises: a recirculating means for adjustably returning a part of exhaust gas from an internal combustion engine to an air intake system to mix it with intake air, a detecting means for detecting at least one operation parameter indicating operational conditions in the engine, an oxygen sensor for detecting the concentration of oxygen in the intake air after recirculating the exhaust gas to the air intake system, and a control means which includes a memory means to store data for determining a control parameter for the engine in response to a plurality of operational conditions in the engine, the operational conditions being defined by a calculated value obtained by the operation parameter and the oxygen concentration in the intake air, and which outputs a signal for correcting the operation parameter on the basis of the data stored in the memory.
