吸入空気量を所定量増量補正するようにしたエン
ジンの吸入空気量制御装置において、エンジンの
駆動系との連結状態を検出する連結状態検出手段
と、該検出手段の出力を受け、エンジンと駆動系
とが非連結状態にあると検出されたときには、上
記吸入空気量の増量補正を制限するとともに、そ
の制限の開始を検出時点から所定時間遅延させる
増量補正制限手段とを設けたことを特徴とするエ
ンジンの吸入空気量制御装置。 In an engine intake air amount control device that increases the intake air amount by a predetermined amount when the engine rotation speed is equal to or higher than a predetermined rotation speed, a connection state detection means for detecting a connection state with a drive system of the engine; In response to the output of the detection means, when it is detected that the engine and the drive system are in a disconnected state, the intake air amount increase correction is limited and the start of the restriction is delayed for a predetermined period of time from the time of detection. What is claimed is: 1. An intake air amount control device for an engine, characterized in that a correction restriction means is provided.
