PURPOSE:To decrease the time required for reading of a control data and to reduce the capacity of a memory, by obtaining plural data through an execution of a subroutine of the table look-up. CONSTITUTION:The output signals of a negative pressure sensor 2 of suction pipe which detects the operating state of an engine 1 and a crank angle sensor 3 are supplied to a central processing circuit 6 via input devices 4 and 5. A memory device 7 is connected to the circuit 6, and the numerical value such as the ignition advance angle value (ADV), exhaustion circulation rate (EGR), etc. is stored in the device 7. Accordingly the control data of both ADV and EGR can be put into a word. In such way, the read-out control data is fed into the circuit 6 to decide the quantity of control after a proper arithmetic process. |
