General The supercharger is a device which increases the engine power output by introducing compressed air into the cylinders. On the 2TZ.FZE engine, the drive power of the crankshaft, via the separate accessory drive shaft, is transmitted through a V.ribbed belt to the supercharger. This produces an excellent power response and generates high torque even in the low rpm ranges.

スーパーチャージャーは、エンジンの低負荷状態では作動しません。
加速および高負荷状態時、
ECM* [エンジンEC]Uは、
磁気(電磁クラッチリレーをオンにして過給を
作動させる磁気(電磁)クラッチに対して信号を出す。
具体的な信号の状態は図などまだ探せてないが、必要なら
実測で概要を掴む事もできそうだ。MAF信号とMG-sigの相関などとか
いくつかの要素から傾向を掴んでおきたいものだ。
2014/3/12(水) 午後 6:57
低速域(IDLなど)、低負荷域などは
電磁クラッチ駆動リレーに信号は送られない。
どの程度の負荷域から通電されるのか、そこからのブースト圧の変化も注目
2014/3/12(水) 午後 7:07
O2sensorの出力特性が若干向上した結果、
21のコードが無くなり、KNKのみ残るようになっている。
状態が変化しているようでもある。
しかし、依然リーン傾向を示す、O2sensorの出力傾向に、他の
要因も探る必要もありそうだ。
