PURPOSE:To improve the mass production effect of electronic fuel injection control units and reduce cost by driving six injectors of a 6-cylinder engine by means of four injector driving circuits of said control unit. CONSTITUTION:Solenoids 21-26 for each injectors for six cylinders #1-#6, are connected to four driving circuits 11-14 which are driven by four injector driving circuits of an electronic fuel injection control unit. The solenoids 21, 22 for cylinders #1, #2 are connected to the first driving circuit 11, and the solenoid 23 for the #3 cylinder is connected to the second driving circuit 13. The solenoid 24 for the cylinder #4 is connected to the third driving circuit 14, and the solenoids 25, 26 for the cylinders #5, #6 are connected to the fourth driving circuit 12. Thereby, the mass production effect of control units can be improved, enabling reduction in cost.
