近十年来,随着柴油机运用可靠性的提高,使用寿命和技术经济指标已成为头等重要的技术课题之一。这一课题的解决,在很大程度上取决于及时地确定柴油机零部件的技术状态。为此,一方面必须确定应该检查什么和用什么方法去检查,另一方面应该决定需要哪些设备。 In the past decade, as the reliability of diesel engines has been enhanced, the service life and technical and economic indicators have become one of the first important technical issues. The solution to this issue depends to a large extent on determining the technical status of diesel engine parts in time. To do this, on the one hand, it must be determined what should be checked and what method should be used to check on the one hand and on the other hand what equipment should be required.
