| Abstract(J) | エンジンのピストン摩擦力を高回転まで計測する浮動ライナーの計測技術を開発した．特徴は，ライナーを高い剛性で保持する両側支持構造の採用と，振動ノイズのキャンセル方法を新規に導入した点である．これにより，4000r/minまで高い繰り返し精度（FMEP 3σ<0.5kPa）でピストン摩擦力を計測できる． Translation |
| Abstract(E) | A floating-liner measurement technique was developed, which quantifies piston friction force under fired engine operation over a wide speed range. To suppress thermal-stress–induced drift in the liner caused by combustion temperature, a double-liner structure was adopted. The liner assembly is held with high rigidity by a double-sided support configuration, in which force sensors support the double-liner from both sides. In addition, acceleration sensors installed on both the double-liner and its support structure are used for a newly introduced vibration-noise cancellation method. Using this apparatus and the proposed cancellation method, high repeatability of piston friction-force measurement up to 4000 r/min was confirmed, and the variation in FMEP was less than 0.5 kPa in terms of 3σ. |
