Description
2 リフト制御部
3 リフト量上限値制御部
Claims (2)
- シリンダ内に吸排気バルブのバルブ本体を電子制御によりリフト量上限値以下の所望のリフト量でリフトさせるリフト制御部と、
エンジン回転速度が第一の閾値未満のときは、リフト量上限値を前記バルブ本体が機械的にリフト可能な最大値とし、
エンジン回転速度が第一の閾値から第一の閾値より高い第二の閾値までの間であるときは、リフト量上限値を機械的にリフト可能な最大値から0までエンジン回転速度の上昇に応じて直線的に低下させ、
エンジン回転速度が第二の閾値を超えているときには、リフトを禁止するリフト量上限値制御部とを備えた弁開閉制御装置。 - 第二の閾値は、吸排気バルブとピストンが衝突しないことが保証されるエンジン回転速度に設定された請求項1記載の弁開閉制御装置。
