Leaning device for internal combustion engine i.e. diesel engine, has mistake learning section learning mistake between ideal parameters and measuring parameter to be computed by measuring parameter-calculation section

摘要

The device has a measuring parameter-calculation section computing a current measuring parameter based on a measurement result of a measuring section (50). An ideal parameter-maintaining section obtains the ideal parameter in accordance with the current average rotation speed of a ROM (54) and rewritable non-volatile memory (56). A mistake learning section learns a mistake between the ideal parameters obtained by the ideal parameters-maintenance section and a measuring parameter to be computed by the measuring parameter-calculation section.
