Simultaneous Measurement of Deposition Amount of Diesel Spray Impinging on Oil Film and Oil Film Thickness Using Double Laser Induced Fluorescence Method

ダブルレーザ誘起蛍光法を用いた油膜に衝突する ディーゼル噴霧の付着量および油膜厚さの同時計測

Post-injection has been attracted attention as the Diesel Particulate filter regeneration method. However oil dilution caused that fuel spray impinges oil film on cylinder liner has seen as a problem is an issue which cannot be ignored. Because oil dilution is leading to deterioration of sliding properties of piston and thermal efficiency, there is need to clarify spray impingement behavior on oil film. In this study, the authors simultaneously measured deposition amount of diesel spray impinging on oil film and oil film thickness using Double Laser Induced Fluorescence method. As the result of measurement using DLIF method, it was found that a large difference of amount deposition of fuel spray impinging on dry wall and oil film.エンジン筒内で噴射された燃料がシリンダライナ上の油膜に衝突付着することは燃費や摺動性に多大な影響を及ぼす.本研究では,オイル油膜に衝突するディーゼル噴霧の付着量およびオイル油膜厚さの同時連続計測を可能とする2色LIF法の構築を行った.
