气缸套的穴蚀问题,直至今天仍然是个现实问题。其原因是没有在发动机设计阶段就能估量穴蚀情况的通用判据,此外也没有简便的测量方法,来测量运转中发动机的气缸套穴蚀情况。因此,在研制新发动机的过程中,穴蚀问题时常被忽视了。鉴于这种情况,李斯特研究所(AVL)开始了研制一种能直接检查发动机穴蚀情况的测量方法的工作。在这项研究中,使用了固体声绝缘的石英压力传感器。正如本报告将要表明的,对于气缸套流体穴蚀的探测,对于所采取的防止穴蚀的措施的评价,它都是一种非常灵敏的指示器。一、引言尽管内燃机的技术水平很高,但至今仍然存在不少问题,其中大部分只能通过在柴油机 The problem of cavitation of cylinder liner is still a real problem until today. The reason for this is that there is no general criterion for estimating cavitation at the engine design stage and there is no easy way to measure cavitation in the cylinder liner of an engine during operation. As a result, cavitation problems are often overlooked in the development of new engines. In view of this situation, the Lister Institute (AVL) began work to develop a measurement method that directly inspects engine cavitation. In this study, a solid acoustic insulated quartz pressure sensor was used. As this report will show, the detection of fluid cavitation in cylinder liners is a very sensitive indicator of the measures taken to prevent cavitation. I. INTRODUCTION Although the technical level of internal combustion engines is very high, so far many problems still exist, most of which can only be solved by using diesel engines
