Description
作業機の負荷率(%)
={(Ract−Ridl)/(Rmax−Ridl)}×100
として算出されるものである。
エンジンの負荷率L(%)
={(Ract−Ra)/(Rb−Ra)}×100
より算出される。
また、一般式としては、
エンジンの負荷率L(%)
={(Ract−Ridl)/(Rmax−Ridl)}×100
として表される。
尚、実ラック位置Ractが、アイドルラック位置Raに一致するとき、エンジンの負荷率91は0%となる。
エンジンの負荷率(%)
=(Nact/Nset)×100
より算出される。
Rb 制限ラック位置
Ract 実ラック位置
Nact 実エンジン回転数
Claims (2)
- 回転数設定手段と、回転数検知手段と、ラック位置検知手段と、燃焼後の排気ガスの一部を吸気側に再循環させるEGR装置と、エンジン制御装置を備え、該EGR装置の再循環量を回転数に応じて変更制御可能とする電子制御式エンジンにおいて、実エンジン回転数と、電子ガバナ装置の実ラック位置とを検知して、実エンジン回転数と、電子ガバナ装置の実ラック位置と、出力補正後の制限ラック位置とにより負荷率を演算し、前記負荷率から出力補正後のEGR開度を演算し、EGR開度を制御することを特徴とする電子制御式エンジン。
- 前記実エンジン回転数を所定時間における平均実エンジン回転数とし、前記実ラック位置を所定時間における平均実ラック位置として演算したことを特徴とする請求項1に記載の電子制御式エンジン。
