摘要

柴油燃烧火焰的红外波段光谱包含燃烧过程中中间或最终产物的各种信息。将光纤支架插入直喷式发动机的柴油燃烧室,研究了不同喷油量和增压压力下的火焰光谱。进一步,他们研究了不同注入量和点火时间下的火焰光谱和火焰温度,并部分明确了红外范围内的波段光谱行为,可能是由H2O和其他未知物质发射的。此外,他们还证实了一些未指明的吸收光谱的存在。

Behavior of Band Spectra of Diesel Combustion Flames in Infrared Ranges
Band spectra in infrared ranges in diesel combustion flames contain various information on intermediate or end products in the combustion process. The authors inserted an optica1 fiber holder into the diesel combustion chamber of DI engine, and investigated flame spectra under various conditions of injection quantities and boost pressures. Further, they investigated flame spectra and flame temperature for various injection quantities and ignition timings, and made partially clear the behavior of band spectra in infrared ranges, presumably emitted from H2O and other unidentified substances. Additionally, they confirmed existence of some unspecified absorption spectra.
