中文摘要:小桐子油在常温下的黏度比柴油大10倍以上,因此研究柴油机燃用小桐子油的燃烧过程,对于小桐子油作为燃料的实际应用有重要的意义。建立了柴油机三维燃烧模型,对柴油机燃用小桐子油的燃烧过程进行了模拟。模拟所得的气缸压力与试验测试结果较为吻合。通过三维燃烧模拟对缸内的流场、温度场及平均温度的变化进行了分析,发现燃用小桐子油时柴油机的喷油时刻比燃用柴油时略有提前。燃烧始点较早,预混燃烧峰值提前,燃烧持续期较大。

Abstract:A 3-D combustion model considered the characteristics of Jatropha curcas oil was established, the combustion process of diesel engine fueled with Jatropha curcas oil was simulated. Simulation results of the cylinder pressure fitted well with the results of test. The flow field, temperature field, and mean temperature in cylinder were analyzed by the simulation. It is found that the injection timing is advanced when the engine fueled with Jatropha curcas oil. The timing of combustion is advanced, the peak premixed combustion is also advanced, and the combustion duration is longer than the engine fueled with diesel fuel.

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.
