摘要

目前全世界的車用柴油以趨向低硫化，硫含量降至＜0.05wt％，而低硫柴的潤滑性比傳統柴油差，一般的解決方式為加入潤滑性添加劑，本文則測試六支商用潤滑性添加劑的潤滑性能及相關的無傷害性試驗。
由測試結果可知，在六支柴油潤滑性添加劑中，其潤滑性、保持噴油嘴清潔及氧化穩定性試驗皆可通過，而其中有一支在添加劑與重型柴油車用潤滑油相容性試驗結果不合格，而有另一支添加劑在儲存穩定性試驗結果不合格，因此柴油潤滑性添加劑的使用，除了須注意柴油之潤滑性外，亦須注意一些無傷害性。

The sulfur content of automotive diesel has been reduced to 0.05 wt%max.worldwide. The majority of low sulfur diesel fuel marketed today are treated with an additive to enhance the lubricity of the base fuel. The lubricity and no-harm performances of six additive samples were evaluated.
The testing results showed that the lubricity, injector coking tendency and accelerated (oxidation) stability tests were all pass for the six additives samples. Only one sample was fail in the compatibility of lubricity additive with heavy duty diesel crankcase lubricants test. The other one sample was fail in the package storage stability test. Then, the lubricity additive package must pass lubricity and extensive no-harm test.
