摘要： There is provided an engine control apparatus that makes it possible that, even in the case where an abnormality occurs in a microcomputer and the operations of the injectors in a series of cylinders are interrupted, there is obtained continuous driving without interruption of the engine, when the microcomputer is restored to normal condition. The microcomputer stores in a backup RAM the injection cylinder and the injection fuel amount at a time when a main fuel injection control means sequentially outputs a drive signal to each of the injectors of the cylinders. After the microcomputer 11 is reset due to detection of an abnormality therein and then is restarted, the post-resetting injection cylinder determining means 31 in the microcomputer determines cylinders into which fuel could not be injected during reset period, based on an fuel injection cylinder that has been stored in a backup RAM 11a at a time immediately prior to the resetting, and fuel is immediately and asynchronously injected into the determined cylinders at an injection fuel amount that has been stored in the backup RAM 11a at a time immediately prior to the resetting.
