    • The invention relates to a method of testing internal combustion engines. First testing units for internal combustion engines are provided at a plurality of peripheral locations on a turntable, and a testing chamber having a second testing unit is provided at one side of a carrying-out path running from the turntable. Each internal combustion engine is first warmed up by one of the first testing units on the turntable and thereafter it is subjected to adjustment in operating conditions. Subsequently, the internal combustion engine is delivered to the second testing unit in the testing chamber in which abnormal noise and vibration measurement and collection of data during engine operation are made.
    • 本发明涉及一种测试内燃机的方法。 用于内燃机的第一测试单元设置在转台上的多个周边位置处,并且具有第二测试单元的测试室设置在从转盘延伸的运行路径的一侧。 每个内燃机首先由转台上的第一个测试单元之一加热,然后在操作条件下进行调节。 随后,内燃机被输送到测试室中的第二测试单元,其中在发动机操作期间进行异常噪声和振动测量以及数据采集。
