Controller for combustion engine, converts predicted exhaust gas oxygen concentration into at least one of 3 error values for injection quantity, duration and pressure, and stores in correction data record

摘要

The device computes a predicted exhaust gas oxygen concentration to control at least either an exhaust gas feedback or fuel injection quantity and has a correction data record for storing a learning value and a correction device. The correction device (700) converts the predicted concentration of exhaust gas oxygen into at least one of three errors values for injection quantity, duration and pressure and stores it in the correction data record.
