本科毕业论文题目：AVLBOOST软件模拟分析配气相位对4100QBZL柴油机油耗影响的数据分析学院：姓名：学号：专业：年级：指导教师：二00一一年五月毕业论文题目摘要中文摘要：本文利用AVLBOOST软件建立了4100QBZL柴油机模拟计算模型。利用所建立的模型，对柴油机全负荷工况下，n=1400,n=2200,n=2600,n=3200r/min四种转速情况下的配气相位角对有效燃油消耗率的影响进行了模拟计算，并与实验数据进行了对比。结果表明，模拟数据与实验数据能较好的吻合，从而验证了该机工作过程模型的正确性。在此基础上，对4100QBZL柴油机的配气相位进行了优化计算，通过分析各配气相位角度对柴油机油耗的影响，确定了该柴油机的最佳配气相位。同时，对4100QBZL柴油机的结构参数进行了改进，并对改进后的柴油机和原机做了对比实验。结果表明，改进后柴油机经济性得到一定的改善。达到了本文研究的目的。关键词：avlboost；4100QBZL柴油机；配气相位；有效燃油消耗率。TheDataanalysissimulatedbyavlboostsoftwareabouthowthevalvetiminginfluenceeffectivespecificfuelconsumptionofthe4100QBZLdieselengineAbstract:ThispaperusingAVLBOOSTsoftwareestablishsimulationcalculationmodelof4100QBZLdieselengine。Usingtheestablishedmodel,westudyhowthevalvetiminginfluenceeffectivespecificfuelconsumptionofthedieselengineinthesituationoffullloadconditions,n=1,400,n=22,n=2600,n=3200r/minfourspeedsituation,andcomparedwiththeexperimentaldata.Resultsshowthatsimulationdatacanwellagreewiththeexperimentaldataandverifythecorrectnessofthemachineworkingprocessmodel.Onthisbasis,simulatetheworkingprocessoftheof4100QBZLdieselengine,accordingtoitsresults,tooptimizeitsvalvetimingandfinallydetermineitsbestvalvetiming.Meanwhile,improvethestructuralparametersofthedieselengineandcontrasttheeffectivespecificfuelconsumptionoftheimproveddieselengineandthatoftheoriginalengine.Resultsshowthateffectivespecificfuelconsumptionoftheimproveddieselenginehavebeenimproved.itachievethepurposeofthisstudy.Keywords:avlboost;4100QBZLdieselengine;valvetiming;effectivespecificfuelconsumption.毕业论文题目目录1绪论........................................................................................................................................................-1-1.1前言.........................................................................................................................................................-1-1.2AVLBOOST软件......................................................................................................................................-1-1.3发动机配气相位、油耗以及两者之间的关系.....................................................................................-3-1.31配气相位..........................................................................................................................................-3-1.32燃油消耗率......................................................................................................................................-4-1.33配气相位对燃油消耗率的影响......................................................................................................-4-1.4配气相位的调节......................................................................................................................................-4-1.41配气相位调节的主要原则...............................................................................................................-4-1.42现代配气相位调节的方法及结构特点...........................................................................................-4-1.54100QBZL柴油机简介............................................................................................................................-5-2模拟试验......................................................................................................................................................-6-2.1模拟试验目的.........................................................................................................................................-6-2.2模拟试验方案.........................................................................................................................................-6-3模拟试验结果与分析..................................................................................................................................-6-3.1进气提前角与柴油机油耗的关系曲线..................................................................................................-6-3.2进气迟闭角与柴油机油耗的关系曲线..................................................................................................-8-3.3排气提前角与柴油机油耗的关系曲线..................................................................................................-9-3.4排气迟闭角与柴油机油耗的关系曲线................................................................................................-10-4发动机台架试验........................................................................................................................................-12-4.1实验目的...............................................................................................................................................-12-4.2实验内容...............................................................................................................................................-12-4.3试验方法及主要试验设备仪器...........................................................................................................-12-4.4实验结果及分析...................................................................................................................................-13-5结论...................................................................................................................................
