Abstract
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 microcomputeris reset due to detection of an abnormality therein and then is restarted, the post-resetting injection cylinder determining meansin 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 RAMat 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 RAMat a time immediately prior to the resetting.
