A finite element model of a diesel engine crankshaft is established with ANSYS and FE-SAFE softwares. Then the tor- sional moment and fatigue life of crankshaft are calculated. Finally the crankshaft torsional test is carried out on test bench, the simula- tion results of the finite element software are consistent with experimental results, and the results show that: the combination method of simulation software and bench test proves the journal fillet of crankshaft connecting rod is the weakest part of crankshaft torsional fatigue, and it provides an important significance for the design and production of crankshaft.

为研究直喷汽油机壁面引导型燃烧系统和气流引导型燃烧系统对起燃工况炭烟生成的影响,在光学单缸发动机台架上进行了GDI汽油机燃烧火焰可视化的试验.研究结果表明,汽油机在起燃工况运行时,采用壁面引导型的燃烧系统由于需要活塞对喷雾雾束进行引导以在点火时间窗口内形成容易着火的混合气,导致大量扩散火焰的产生,炭烟生成加剧;而气流引导型直喷燃烧系统避免了喷雾雾束与燃烧室壁面以及活塞顶面的接触,且有组织的强烈滚流
