簡 介
美孚佳特330和430是總堿值達30的優質發動機油，專為燃燒重油的船用柴油發動機而設計。這一新系列發動機油顯示了卓越的與重油相容特性。從而達到了發動機高度清潔的效果，特別是在發動機曲軸箱和凸輪軸部份，同時也顯露出卓越的抗高溫氧化性和保持穩定性、低揮發性、承受負荷性及防腐蝕性能。
用 途
這一新系列產品是美孚公司經過廣泛開發研究的結果，同時結合了美孚專利的殘油測試化驗，它滿足了用作為遠洋、沿海及內河各類型中速筒型活塞柴油機作為主機或付機的要求。美孚佳特30系列是為滿足燃燒重質燃油發動機的需要而設計。它們也被推薦用于新一代高功率的二沖程或四沖程發動機。
優 點
美孚佳特30系列油品有以下優
點推薦使用：
·提供卓越燃料/潤滑油的相容性能
·保持曲軸和凸輪軸有良好的工況狀態
·減少活塞環的沉積物
·良好的總堿值持續性從而達到防腐蝕性及更長的潤滑油壽命
·因長久的滑油壽命從而降低耗油量
·良好的油水分離性
性 質
美孚佳特330和430配方具有卓越的抗氧化性和提高發動機清潔性，從而防止磨損。對于因高硫份燃油而形成的強酸，有良好的中和作用。減少酸性物質進入曲軸箱而致活塞環、缸套及軸承被腐蝕的機會。
Product Descr1ption
Mobilgard 330 and 430 are premium quality 30 TBN engine oils designed for use in the most severe residualfuelled marine medium-speed diesel applications. These new marine diesel engine oils provide outstanding residual fuel compatibility characteristics for excellent engine
cleanliness, especially in crankcase and camshaft areas. They provide excellent high temperature oxidation and thermal stability, low volatility, load carrying properties and corrosion protection.
Application
This new Series of oils is the result of an extensive Research and Development program, incorporating Mobil’s exclusive RFD(Residual Fuel Detection) Test.They meet the requirement of medium speed trunk piston engines used as main propulsion and auxiliary diesels on deep-sea
vessels, and as main propulsion engine on coastal and river ships. Mobilgard 30 Series oils are designed to meet the needs of engines operating on heavy fuel. They are recommended for use in the latest model high power two and four cycle diesel engines.
Benefits
Mobilgard 30 Series oils provide the following benefits
when used as recommended:
·Provide excellent Lube/Fuel Compatibility
·Maintain camshaft apaces and crankcase in good
condition
·Reduce piston ring belt deposits
·Good TBN retention resulting in protection against
corrosion and providing long oil life
·Long oil life and good oil consumption control
·Separates easily from water
Properties
Mobilgard 330 and 430 are formulated to provide excellent resistance to thermal degradation and to promote a high level of nginecleanliness with protection against wear. They have good resistance to oxidation and viscosity increases over long operating periods. High alkalinity
reserves in these oils provide superior protection in neutralising the strong acids resulting from the use of high sulphur fuels that find access to the crankcase to promote oil degradation, ring, cylinder and bearing corrosion. Characteristics 特 性 | 以 下 所 列 數 據 除 特 別 注 明 外， 均 為 典 型 值
