The auto-ignition of tire usually causes major safety accidents to automobile. From the viewpoint of temperature, this pa- per investigates causations of auto-ignition and combustion property about tire. By analyzing causations of auto-ignition, which is related to rolling tire friction heat, modeling of frictional heat generation on periodically deforming. Through the research of drum brake frictional heat source, the model about friction heat transfer from drum brake to wheel rim is built by using “Radiation Heat Transfer Network Method”. According to the tire combustion test, the lost mass curve and model could be obtained, including the distribution picture of the temperature about different burning phase when the tire is burning. Finally, some rational and effective measures are presented to prevent and control accidents caused by auto-ignition of tire.

建立基于VGT的二级可调增压柴油机高海拔工作过程仿真模型,研究了不同海拔、不同工况下VGT叶片调节特性,并通过优化,得到了VGT叶片开度最佳MAP,在此基础上,进行了二级可调增压系统与柴油机不同海拔匹配性能研究.结果表明:高、低压级增压器与柴油机匹配效果较好,在海拔5500m,除怠速工况外,其余各工况的工作点均处于压气机高效率区.与单级增压柴油机相比,二级可调增压系统总压比随海拔的升高而增大,在海
在一台GDI发动机上进行油品升级试验,研究油品升级前后不同油品对GDI发动机燃烧和排放的影响.研究结果表明,由国四标准的97号汽油升级为国五标准的98号汽油,对于压缩比为9.6的GDI发动机来说,燃烧持续期延长,缸压峰值降低,放热率峰值减小.但油品升级有助于降低GDI发动机的排放特性,98号汽油比97号汽油CO排放降低,HC排放降低,NO的排放平均降低4.9％,微粒排放总数量浓度降低.
