测量发动机机油消耗量的传统方法是采用重量法或体积法,也就是通过测量发动机在运转一段时间前后机油的重量或体积之差来决定机油耗量。这种方法的优点是简便易行,无需专门的测试设备,但其缺点也是显而易见的。由于发动机的机油耗量比较小,为了保证测量精度,试验需要较长的时间(一般在10小时以上),同时测量准确度也较难保证。为了克服重量法的缺点,近年来,
The traditional method of measuring engine oil consumption is to use gravimetric or volumetric methods, which determine the oil consumption by measuring the difference in weight or volume of the engine oil before and after its operation. The advantage of this method is that it is simple and does not require specialized test equipment, but its drawbacks are also obvious. As the engine oil consumption is relatively small, in order to ensure measurement accuracy, the test takes a long time (usually more than 10 hours), while the measurement accuracy is more difficult to guarantee. In order to overcome the shortcomings of the gravimetric method, in recent years,
