ABSTRACT:
An engine controller includes a first calculation unit for calculating an amount of fuel injection and ignition timing by a first 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 first interrupt process, a second calculation unit for obtaining a value representing a proportion of the interrupt execution time contained in one interrupt period in accordance with the period of the first interrupt process and the interrupt execution time and comparing the value of the proporiton with a predetermined value, and an inhibition unit for omitting or inhibiting the execution of a next interrupt process by the first calculation means when the interrupt execution time contained in one interrupt period exceeds a predetermined value.
