摘　　要：喷油嘴偶件喷孔积碳可导致柴油机性能指标下降乃至使用寿命的缩短,研究人员通过对喷油嘴偶件针阀体喷油端的外表面及喷孔的孔壁进行防积碳涂层处理,并进行流量对比试验和热机试验,验证了该喷油嘴偶件经防积碳涂层处理后,能够减小积碳的附着强度和提高喷孔流量系数。The outside of nozzle tip and the inside wall of spray holes are processed with technique of coating for preventing carbon deposit,and flux measurement for no-coated nozzle and coated nozzle are made.The results show that flow coefficient increases and strength of carbon deposit decreases in coating nozzle.

关 键 词：喷油嘴偶件 防积碳涂层 流量
