本文首先分析了柴油机喷油系统精密柱塞偶件、出油阀偶件、针阀偶件的磨损显微形态及磨损机理。其后根据大量的试验结果,提出了诸偶件的磨损极限——这些规范值与传统的数据和提法有所不同。
In this paper, the microscopic morphology and wear mechanism of the precision plunger coupling, the delivery valve coupling and the needle coupling of the diesel injection system are analyzed first. Subsequent to a large number of test results, the wear limits of the couplers were proposed - the values differ from the conventional data and formulations.
