PURPOSE:To use a memory unit having a small memory capacity by devising the configuration of memory data in an engine determining the operation control quantity via the interpolation calculation of two memory data map-retrieved from the operation parameter data. CONSTITUTION:Output signals of a rotation sensor 1, an intra-intake pipe absolute pressure sensor 2, and a water temperature sensor 3 are fed to an ECU5, two basic injection timings as the operation control quantity are determined from a map previously stored in a memory unit 5c based on the engine speed Ne and absolute pressure PB, and the required fuel injection timing is determined via the interpolation calculation of these values. In this case, the memory data of the memory unit 5c are constituted with the control data having the preset number of digits representing the operation control quantity and the digit shift data representing the digit shift quantity of this control data. When the digit shift quantities of two memory data read out from the map are different, both control data are made the same level based on the difference, then the interpolation calculation is performed.
