中文摘要:设计了一套快速压缩机试验台架,并进行了压缩性能试验。在分析液压缓冲、驱动压力等因素对快速压缩机试验台架性能的影响,并进行压缩性能优化后,快速压缩机压缩平均速度大于8m/s,燃烧缸内压缩温度的可控范围为650~1120K。使用DME-O2-N2混合气进行了快速压缩机的燃烧性能试验,观察到了混合气两阶段放热现象与两阶段着火延迟期。在不同的压缩比、压缩温度与压缩压力条件下,对DME-O2-N2混合气两阶段着火延迟期、总着火延迟期的变化规律进行了研究。试验结果表明:在相同初始压力下,随着燃烧缸内压缩温度与压缩压力的增加,DME-O2-N2混合气的第一阶段着火延迟期与总着火延迟期均缩短;在相同压缩温度下,燃烧缸内压缩压力的增加导致混合气第二阶段着火延迟期与总着火延迟期均缩短,混合气第一阶段着火延迟期略有缩短。

Abstract:A rapid compression machine test bench was developed for studying the combustion characteristic of alternative fuel, and the compression performance tests were carried out. After analyzing the influences of the factors such as hydraulic buffer, driven pressure on properties of the rapid compression machine and improving the compression performance, compression speed of the rapid compression machine was higher than 8m/s and the compressed temperature can be controlled in the range of 650~1120K. Combustion performance tests were carried out by using DME-O2-N2 mixtures. The two-stage combustion and two-stage ignition delay time of the mixtures were observed. The two-stage and overall ignition delay times of DME-O2-N2 mixtures were studied under varied compression ratios, compressed temperatures and compressed pressures. Results showed that with the compressed temperature and compressed pressure increased, the first and overall ignition delay times of mixtures were shorten under the same initial pressure. Under a certain compressed temperature, with increasing compressed pressure, the second and overall ignition delay times of mixtures were shorten while the first stage ignition delay time was shorten slightly.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
