D-765-A/B/C高效船舶柴油機汽缸油

產(chǎn)品簡介：

D-765是專為船舶而開發(fā)的十字頭柴油機汽缸油，能為在嚴苛條件下燃燒高硫份燃油，高動力柴油機提供極佳的保護，對此等特殊結(jié)構(gòu)的船舶發(fā)動機能滿足其所有汽缸潤滑之要求。

特殊效益：

*在接觸水（含海水）時，具極強的抗乳化性

*具有絕佳的重負荷潤滑性以保證汽缸和活塞環(huán)之間的完美潤滑

*具有足夠的清凈分散性能，以保證其對活塞環(huán)帶，活塞及氣口之清潔功效

*具高度的酸中和能力，以中和因燃燒而產(chǎn)生的硫酸和硫化物，提供良好的抗

腐蝕性能

*具優(yōu)異的密封性能，以保證燃燒氣體不竄過汽缸套和活塞環(huán)間的空隙

*具良好的儲存穩(wěn)定性

用途：

極適用于船舶高動力在嚴苛工作條件下使用高硫份燃油之船舶十字型柴油機汽缸潤滑。
