The role of nozzle convergence in diesel combustion
Abstract
An experimental study has been performed for identifying the role of injector nozzle hole convergence and cavitation in diesel engine combustion and pollutant emissions. For doing so, five nozzles were tested under different operating and experimental conditions. The critical cavitation number of each nozzle was analyzed. With this value, an estimation of the mixing process at different conditions
obtained. This data is used to explain the combustion results which are analyzed in terms of the apparent combustion time, rate of heat release, in-cylinder pressures, adiabatic temperatures and soot and NOx emissions.Special emphasis is put in developing an expression to explicitly link the mixing process and the injection rate with the rate of heat release. The results show that the fuel–air mixing process can be improved by the use of both convergent and cavitating nozzles, thus lowering the soot emissions. The NOx production, being dependent of the injection rate and the mixing process, does not necessarily increase withthe use of more convergent nozzles.2007 Elsevier Ltd. All rights reserved.

喷嘴会集在柴油机燃烧的角色提取一实验研究适合鉴定喷头喷嘴洞会集和空化的角色执行， 在柴油发动机燃烧和污染物排放物过程中。 为如此做，5 个喷嘴被在不同的操作和实验工况下面测试。 每个喷嘴的关键的空化数目被分析。 由于这价值，在获得的不同的条件的混合的过程的估计。 这数据用来解释被就明显的燃烧时间而言分析的燃烧结果， 热的比率松开，在汽缸方面的压力， 绝热应变温度和煤烟和氧化氮emissions.Special重点被放进发展表示给明确连接混合的过程和那些注射 有热释放的比率的比率。 结果显示混合过程的燃料空气可以被使用两个集中并且气蚀的喷嘴改进，因此降低煤烟排放物。 氧化氮生产，由于注射比率和混合的过程而依靠，不一定增加withthe 使用更集中的喷嘴。 2007 Elsevier有限公司版权所有。 关键字： 柴油机； 直接的注射； 喷嘴； 空化
