Abstract

PURPOSE: To digital-control warming up operation by corresponding the actual number of rotation with the programmed number of rotation by programming, in advance, the air-fuel ratio and the number of rotation during the warming up operation which are set following up the temperature change of the engine.
CONSTITUTION: An air-fuel ratio control device 32, a warming up control device 33, an ignition device 34, a fuel pump 43, and so on are controlled by the results of operation of CPU22 of a control device 18. Also, the condition of the engine temperature is digital-converted to obtain a digital value to detect the warming operation. Then, the fuel compensating value and the standard speed of rotation of engine for warming up are detected by the digital value, and the standard speed of rotation and an actual speed of rotation are compared. By comparing the results, the air rate is controlled by an air solenoid valve 15 to bring the actual speed of rotation of the engine close to the standard speed of rotation. Then, the fuel feeding data, which is corrected by the fuel compensating value, is searched corresponding to the rate of air, and a fuel solenoid valve 11 is controlled by the compensating value to control fuel for the engine.
