抄録 | 燃焼室を大小二つの燃焼室に分割し,小燃焼室で先に着火・燃焼させると多段のHCCI燃焼が実現できる.本報ではその時の燃焼,性能に及ぼす圧縮比,および大燃焼室,小燃焼室同一の燃料の適用およびEGRの各影響について調査した.その結果,最高図示熱効率47.7%,最高図示平均有効圧628kPaを得た. |
抄録(英) | Homogeneous charge compression ignition (HCCI) combustion is promising a new combustion system reducing NOx and PM simultaneously without any penalty of fuel consumption. However, the operational range of the HCCI combustion system is limited because of some issues such as poor control of ignition timing and the excessive rate of pressure rise. In this study, a new combustion system based on the HCCI combustion process has been proposed. The combustion system has a divided combustion chamber of two parts, one is small and the other is large. On the combustion system, at first, ignition takes place in the small chamber, and then the burned gas ejected into the large chamber to ignite the mixture in the large chamber. In the combustion system, the combustion process in the large chamber is aimed to go on same manner of the HCCI combustion process. This paper presents the effects of compression ratio, supplying same fuel to the large chamber and the small chamber and EGR on engine performance, combustion characteristics and exhaust emissions. 翻訳 |
