汽车发动机的密封技术浅析

Analysis of Sealing Technology of Automotive Engine

在汽车技术飞速发展的今天,客户对汽车发动机的要求不断提高,追求更高的动力性、经济性及排放性能,对发动机零部件可靠性要求更高,其中,发动机的密封性能是评价汽车质量的一个重要指标,汽车运行中发动机工作介质的泄漏,会直接影响汽车发动机的工况。因此,发动机密封技术研究日益成为当前汽车发展的主题。本文从密封设计、密封质量问题、密封验证等方面阐述了当前对汽车发动机密封技术发展的要求。

With the rapid development of automotive technology, the customer＇s demand for automotive engine is increasing, pursuing higher power, economy and emissions performance, and higher reliability of engine parts, in which the sealing performance of the engine is an important indicator of evaluating the quality of the car. The engine working medium leak in the operation of car will directly affect the working conditions of automobile engine. Therefore, the research on engine sealing technology is becoming the main subject of current vehicle development increasingly. This paper expounds the requirements for the development of current automotive engine sealing technology from sealing design, sealing quality and sealing verification.
