Abstract

A engine control apparatus includes: a read-only memory (53) storing data needed for startup control and normal control of an engine (1); and a control processing unit (55) operating the startup control and the normal control of the engine (1) on the basis of the data stored the read-only memory (53); the control processing unit (55) executing: an initial processing containing a startup area check processing for checking a storage area of the data needed for startup control (53a) in the read-only memory (53); a startup control processing for performing the startup control of the engine (1) on the basis of the data needed for startup control; a normal area check processing for checking the storage area of the data needed for normal control (53b) in the read-only memory (53); and a normal control processing for performing normal control of the engine (1) on the basis of the data needed for the normal control.
