D-765-A/B/C 高效船舶柴油機汽缸油
產品簡介:
D-765是專為船舶而開發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,對此等特殊結構的船舶發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,以中和因燃燒而產生的硫酸和硫化物,提供良好的抗
腐蝕性能
* 具優異的密封性能,以保證燃燒氣體不竄過汽缸套和活塞環間的空隙
* 具良好的儲存穩定性
用途:
極適用於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。

D-765-A/B/C PREMIUM MARINE DIESEL ENGINE CYLINDER OIL
DEscriptIONS:
D-765's were developed to provide outstanding protections for marine diesel engine cylinders with large horsepower output and operating under the most
severe working conditions while using high sulfur content fuels. In total, they are ideal engine oils that satisfy the special characteristics of the engine cy -slinder, which are of a particular operating mechanism widely used in marine ships.
FEATURES:
* Resistance to formations of emulsions when exposed to water (including
salty water)
* Providing superb lubrication under heavy load running conditions, to ensure
perfect lubrication between cylinder surface and piston ring
* Good dispersion and penetrating characteristics, to ensure complete covera-
ge of all necessary parts to be lubricated
* Ideal detergent / dispersant capabilities, to ensure cleaning performance to
piston ring, piston and valve ports
* Very high neutralization ability, to ensure anti-corrosion properties by neutra-
lizing sulfur acid and sulfur-oxides arising from combustion
* Excellent sealing property,to ensure non-passing of combustion gases throu-
gh seams between the piston ring and the cylinder surface
* Having good storage stability for long period of time(1-2 year)
APPLICATIONS:
It is an excellent lubricant for marine diesel engine cylinder with high horsepower output and operating under severe conditions while using high sulfur content fuels.
