気流量信号処理装置。 A fuel supply means and an intake air flow rate detection means are provided upstream of the branch part of the intake manifold, and a new weighted average is obtained by weighted averaging the previous weighted average value and the latest value of the intake air flow rate detection value. In an intake air flow rate signal processing device for an internal combustion engine, the apparatus includes an intake air flow rate signal output means for outputting a value as a signal value of an intake air flow rate used for setting a fuel supply amount. , when acceleration is detected, the weighting of the latest value is set to be larger than the weighting of the past weighted average value, and when non-acceleration is detected, the weighting of the past weighted average value in the weighted average by the intake air flow rate signal output means is set to be the weighting of the latest value. 1. An intake air flow rate signal processing device for an internal combustion engine, comprising means for switching weighting to a larger weight.
