| Abstract(J) | エンジンの今後の熱効率向上の鍵は，壁面冷却損失の低減技術である．特に拡散燃焼主体のディーゼルエンジンでは，熱効率向上のため更なる圧縮比増加が予想され，噴霧火炎の壁面衝突や不均一な壁面温度分布が冷却損失低減を考える上で課題となる．本報では，新エィシーイーで近年研究した熱損失低減技術の幾つかを紹介する． Translation |
| Abstract(E) | One of the key technologies for further improvement in thermal efficiency of reciprocating engines should be cooling loss reduction based on the more detailed understanding of heat transfer phenomena. In addition, further increase in compression ratio especially for diesel engines,in which diffusion combustion is dominant, is anticipated to achieve significant improvement in thermal efficiency. Therefore, spray flame impingement or interference to the wall and resulting inhomogeneous surface temperature distribution are the major issues to consider cooling loss reduction by heat insulation technique.This report introduces some examples of cooling loss reduction technology, which have been studied for recent years. |
