- 支持スリーブがタイロッドを部分的に取り囲むように少なくとも1つの固定機構を介してシリンダのタイロッドに固定可能である、径方向および軸線方向に分割された支持スリーブを備える、内燃機関のシリンダの燃焼室内の圧力を燃焼室の外部で測定するための内燃機関用シリンダ圧測定装置であって、
前記支持スリーブのうち分割によって径方向に互いに分離された少なくとも2つのセグメントに容量性測定システムのコンポーネントが割り当てられ、それにより、測定されるシリンダ圧によって引き起こされるタイロッドの長さの変化が、分割によって径方向に分離された前記セグメントの、したがって前記容量性測定システムの前記コンポーネントの軸線方向移動を引き起こすようになっており、
前記支持スリーブの前記セグメントが、リング状要素によって互いに位置合わせされ、
前記リング状要素が径方向に分離された前記セグメント間に配置されるシリンダ圧測定装置。 - 前記支持スリーブが、径方向および軸線方向での分割により4つのセグメントに分離される、請求項1に記載のシリンダ圧測定装置。
- 前記支持スリーブの前記セグメントが、その外端部に、内面に設けられたそれぞれ1つの突起部を備え、前記突起部が、前記タイロッドに取り付けられた状態で、前記タイロッドの外表面を押圧する、請求項1または請求項2に記載のシリンダ圧測定装置。
- 前記シリンダ圧測定装置が、複数の前記固定機構を介して前記シリンダのタイロッドに固定可能であり、前記固定機構それぞれが、U字形の締付けリング、溝ナット、締付け部材および締付け板を含み、前記締付けリングが、その外端部で、前記締付け板、前記締付け部材および前記溝ナットを介して前記締付けリングに加えられる力が前記支持スリーブの前記セグメントを前記タイロッドに押しつけるように、前記支持スリーブのセグメントを取り囲む、請求項1から請求項3までのいずれか1項に記載のシリンダ圧測定装置。
- 前記容量性測定システムの前記コンポーネントが、ドエルピンを介して前記支持スリーブの径方向に分離された前記セグメントと連結される、請求項1から請求項4までのいずれか1項に記載のシリンダ圧測定装置。
