PURPOSE:To calculate the basic injection easily with high accuracy in a system employing a Karman sensor intake air detection, by employing a map storing the relation with the basic injection corresponding with the engine rotation and the output of Karman sensor. CONSTITUTION:The period of output pulse or the intake air corresponding with said period is calculated through first calculating means 3 on the basis of the output signal from a Karman sensor 1 for producing pulse signals of such period as reversely proportional with the intake air. While the engine rotation is calculated through second calculating means 4 on the basis of the output signal from an engine rotation sensor 2. Then, a plurality of engine rotations are read out through read-out means 6 with correspondence to the outputs from both calculating means 3, 4 while the basic injection is read out from memory means 5 storing the period of output pulse from Karman sensor 1 or the basic injection corresponding with the intake air as maps. The basic injection interpolated on the basis of the basic injection and both calculation results is produced from interpolating means 7. |
