PURPOSE:To enhance the mass production effect of an electronic fuel injection control unit together with its cost down by providing contrivance for driving 6 injectors allotted to respective 6 cylinders by means of 4 injector driving circuits. CONSTITUTION:A cylinder group in the rear row consists of three cylinders #1-#3 and the same one in the front row consists of other three cylinders #4-#6. The first driving circuit 11 drives the injectors of cylinders #1 and #3. The second driving circuit 12 drives the enjectors of cylinders #4 and #5, the third driving circuit 13 drives the injector of cylinder #2 and the forth driving circuit 14 drives the injector of cylinder #6. Since the six injectors are driven by those four driving circuits like this, the mass production effect of an electronic fuel injection control unit is enhanced to suggest a plan of cost reduction.
