3.1 Characteristics of the work to be evaluated
Technical test table is to evaluate the filter's ability to remove harmful destructive cycles existing in the system. During the use of the filter, various impurities from micro-particles to large particles are blocked after replacement. Therefore, the surface of the filter can be blocked by the particles. Therefore, this performance has been fully considered when formulating this test specification. In the test system, the filter is tested for age and the efficiency of the filter is determined. When the filter is tested on a bench, there are many differences in the performance of the filter. When it is installed on the engine, the different working characteristics will make the filter components have obvious differences during the bench test.
