【摘要】 本文设计了一台快速压缩机,用于均质压燃及其他燃烧过程燃料化学反应动力学特性的研究。压缩机采用间隙活塞,活塞行程为500mm,压缩时间约30ms,压缩比变动范围为6~22.5。对快速压缩机的实验数据重复性、可靠性和燃烧过程均匀性进行了测试,测试结果表明:该台压缩机实验数据的重复性良好且燃烧过程满足HCCI燃烧实验要求。此实验数据结果与密歇根大学快速压缩机实验结果进行了比较,两台压缩机实验数据最大偏差仅9.68%,具有很高的可靠性,该台压缩机完全适于燃料化学反应动力学的研究。更多还原

【Abstract】 A rapid compression machine was developed at Tsinghua University(TU) to study fuel combustion chemistry and combustion processes related to internal combustion engines.A creviced piston was used and the piston stroke was 500 mm with the compression duration time of 30 ms.The compression ratio varies from 6 to 22.5.Some preliminary tests were conducted to demonstrate its capabilities in studying homogeneous ignition process.The results show excellent data repeatability of the new RCM and the ignition process is very homogeneous.Isooctane ignition delay data acquired from this RCM were compared with that from Michigan University rapid compression facility with the maximum fractional difference less than 9.68%.The new TU-RCM is very well developed and well-suited for fuel combustion kinetics research.更多还原
