【摘要】 本文为《内燃机》1975年载"V 型发动机的偏振"(上、下)两文的续篇。通过对三种不同类型的 V 型发动机喷油泵凸轮轴的扭振测试和分析。进一步证实前文关于在所有该类型发动机中均存在偏振的论述,以及这种偏振现象虽然不一定在所有情况均会引起破坏,但也决非微不足道,它的确可能在系统某分支上导致事故。文章还提出了在副系统中出现的若干有待进一步探讨的问题。更多还原

【Abstract】 This is a continuation of an article "Asymmetrical Vibrations in the Vee-type Engine" published in 《Internal Combustion Engine》 in 1975, Here,in this issue,records of torsional vibration of fuel pump camshafts of three different kinds of Vee-type engines are analyzed and interpreted,showing that asymmetrical vibrations exists in all the engines and,what is more,such pheno- mina,though not inevitably be fatal in each ease,are by no means insignificant, so that should anything go wrong in only one of the twin branches of the system.This analysis gives an additional source to be investigated for remedy when needed.更多还原
