所谓发动机的清洁度是指发动机的被检件被检部位清洁度,常规方法是以从规定的部位采集到的杂质微粒的大小和质量来表示。清洁度不仅影响发动机的耐久性与可靠性,最终影响发动机的使用寿命。因此,保证发动机的清洁度应从生产发动机开始直到报废贯穿于始终,以最大限度发挥发动机各部件的使用性能,延长发动机的使用寿命。这对提高质量、降低保修成本、提高经济效益具有重要意义。 The so-called cleanliness of the engine refers to the cleanliness of the seized parts of the engine, the conventional method is based on the size and quality of the impurity particles collected from the specified location. Cleanliness not only affects the durability and reliability of the engine, ultimately affecting the life of the engine. Therefore, to ensure the cleanliness of the engine should start from the production of the engine until scrapped throughout, in order to maximize the performance of the engine components to extend the life of the engine. This is of great importance to improve quality, reduce warranty costs, improve economic efficiency.
