汽车用油管燃油渗透率测试技术研究

Study on Fuel Permeation Test Technique of Fuel Tube for Vehicle

汽车用油管的燃油渗透是燃油蒸发排放的重要来源,渗透率的测量方法在国内还没有明确依据。本文介绍根据国外的方法和经验开发出的汽车用油管渗透率测试系统,分析该系统的各方面影响因素。实际测试结果表明,该测试技术是可行的和有效的。

The permeation emission from vehicles fuel tubes has a big contribution to evaporative emission. The test method of the permeation still has not a clear gist in our country yet. This paper introduces the test system of permeation developed in according to the external methods and experiences, and analyzes some influence factors. The actual test results show the feasibility and validity of this test technique.
