摘　　要：针对发动机试制阶段气门油封脱落引起故障频发的情况,通过对气门油封拔脱力影响因素分析,充分考虑可行性的前提下,提出从改进装配工艺或气门导管结构方面提升拔脱力两种解决思路,根据气门油封拉压力试验结果比对,得到改进气门导管结构对提升拔脱力效果最好,且不影响装配力,为解决故障提供了最优方案。In view of the frequent failure caused by valve oil seal falling off during engine trial production,through the analysis of the influencing factors of the pull-out force of valve oil seal,under the precondition of full consideration of feasibility,two solutions of improving assembly process or valve guide’s structure to enhance pull-out force were proposed.According to the comparison of valve oil seal pull and pressure test results,the improved valve guide structure has the best effect on lifting the pull-out force,and does not affect the assembly force,which provides the optimal solution to the fault.
