Engine controller.

摘要

The engine controller of the invention comprises first calculation means (1) for calculating an amount of fuel injection and ignition timing by an interrupt process in response to a TDC signal and calculating fuel injection start timing and ignition timing by a higher-order interrupt process having a higher priority than the interrupt process, second calculation means (2) for obtaining a value indicative of a proportion of the interrupt execution time contained in one interrupt period in accordance with the period of the interrupt process and the interrupt process execution time and comparing the value of the proportion with a predetermined value, and inhibition means (3) for omitting or inhibiting the execution of a next interrupt process by the first calculation means when the interrupt process execution time contained in one interrupt period exceeds a predetermined value in the second calculation means.
