摘 要:柴油低硫低芳烃导致润滑性下降, 高压燃油喷射系统的磨损问题突出。磨损以氧化腐蚀和擦伤为主,而对燃油起润滑功效的机理, 则有 3 种假设加以解说。高频往复试验( High frequency reciprocating rigmethod, HFRR)和球 柱试验(Ball on cylinder lubricity evaluator, BOCLE)适宜评定柴油润滑性, 但其评定值与柴油物化分析数据和实际抗磨效果的相关性差。油泵现场试验能较好地反应实际柴油润滑性能。添加剂技术是解决柴油润滑性的首选途径, 低摩擦碳膜(Near frictionless carbon coatings, NFC)是很有前景的抗磨损技术。The continual descending of diesel fuels lubricity originated from large reduction of sulfur and aromatics in diesel fuels caused increased wear in high pressure injection system. The oxidation and scuffing were the main wear causes. There were three hypotheses to interpret fuels lubricating function. High frequency reciprocating rig (HFRR) and ball on cylinder lubricity evaluator (BOCLE) have been conventionally used to evaluate diesel fuels lubricity, but test results showed that poor correlation existed between physical-chemical determinations and lubricating effects. Pump rig tests well reflected the actual fuels lubricity. Additive technology was the principal solution to fuels lubricity. Near-frictionless carbon coatings (NFC) is a promising technology for anti-wear of injection pump.
