简 介
美孚飞马7 0 5 是粘度为SAE 40 的优质燃气机 油。由高度精炼的石蜡质基础油和经过精心挑选的添加剂调制而成， 具有低灰分特性，在以天然气为燃料的发动机内使用，具有最佳的性能。该油含抗磨剂和清洁分散添加剂其出色的抗氧化能力和热稳定性确保了油品具有充分的性能储备， 故使用寿命可以得到延长。
用 途
美孚飞马705 主要为要求低灰分以天然气为燃料的发动机而配制。虽然天然气内无腐蚀性污染物， 使燃用天然气的发动机的润滑并不复杂， 但使用恰当并具有平衡配方的润滑油是必需的， 因它可确保热交换器的清洁、火目前主要有两种类型的燃气机， 即： 电火花点燃式及使用柴油（ 两种类型燃料） 引燃式。美孚飞马7 0 5 主要用于较严荷的电火花点燃式燃气机。由于天然气本身是一种非常清洁的燃料，因而燃烧室的沉积主要来源于润滑油， 基于此， 普通发动机油并不适合电火花点燃式燃气机的润滑。美孚飞马7 0 5 是专为Caterpillar,Supe r ior ,Wauke sha和其他涡轮增压或自然吸气式、中速至高速四冲程燃气机的润滑而设计， 此等发动机要求润滑油具有低至中等灰分， 并具有最高水平的性能和润滑保护。美孚飞马7 0 5内之锌和磷的含量很低， 所以可用于带有催化转换器的发动机。
优 点
美孚飞马7 0 5 系列具有以下优点：
·获各主要设备商确认
·降低燃烧室沉积， 满足燃气机的更高温要 求
·润滑油寿命延长
·减少阀件磨损
·减少换热器淤积
·减少发动机维护， 延长发动机寿命
·抗腐蚀能力强
·抗氧化、抗氮化能力优异

Product Descr1ption
Mobil Pegasus 705 is a premium quality SAE 40 gas engine oil. It is blended from highly refined paraffinic base stocks fortified with carefully selected additives having low ash characteristics giving optimum performance in engines fueled by natural gas. This oil also contains wear resistance and detergent / dispersant additives. High oxidation resistance and good thermal stability ensure adequate performance reserve for extended service life.
Application
Mobil Pegasus 705 is formulated primarily for natural gas fueled engines where a low ash lubricant is required. Although the absence of aggressive contaminants in natural gas makes the lubrication of these engines less complex, a correctly balanced product is vital to ensure clean heat exchangers, long spark plug life and low valve deposits. There are two main types of gas engines i.e., spark ignition or pilot ignition with diesel fuel (dual fuel type). Mobil Pegasus 705 is formulated primarily for use in the more critical spark ignition gas engines. Since natural gas is inherently a clean burning fuel, the main source of combustion chamber deposits will be lubricating oil and for this reason normal engine lubricants are unsuitable for spark ignited gas engines. Mobil Pegasus 705 is designed to provide the highest level of performance and protection in Caterpillar, Superior, Waukesha and other turbocharged and naturally aspirated, medium to high speed four cycle gas engines requiring a medium to low ash level product. With its low levels of zinc and phosphorus Mobil Pegasus 705 can also be used in catalytic converted equipped engines.
Benefits
Mobil Pegasus 705 Series offers the following advantages :
·Major builder approval
·Reduced combustion chamber deposits to cater for the higher temperatures produced by gas engines
·Increased lubricant life
·Good control of valve wear
·Reduced heat exchanger deposits
·Low engine maintenance and long service life
·High resistance to corrosive attack
·High resistance to oxidation and nitrationration
