GS-CHV20 Medium Speed Diesel Engine Oil

Performance and use:
Excellent cleaning and dispersing performance, preventing the pollution of sludge, carbon deposit and heavy oil.
Higher base number can effectively neutralize the strong acid generated by burning high-sulfur fuel, and effectively reduce the corrosion and wear of cylinders and pistons.
Excellent anti-wear performance, ensuring sufficient oil film strength under high temperature and high pressure, and reducing friction and wear.
Unique formula technology keeps the alkali value, effectively prevents the alkali value from decreasing due to oxidation and prolongs the oil change cycle.
Recommended use:
Medium-speed cylindrical piston diesel engine is suitable for lubrication of marine diesel engine burning heavy fuel and engine cylinder and crankcase, including main engine and auxiliary engine.
â—†4012 is used for fuel oil with sulfur content less than 1.5%.
â—†4030 is used for fuel oil with sulfur content of 1.5%-3%.
â—†4040 is used for fuel oil with sulfur content of 3.0%-4.0%.

Description

GS-CHV20 medium-speed diesel engine oil is compounded with deeply refined mineral oil, unique detergent dispersant with high base number, high-temperature antioxidant and antiwear agent, antirust agent and other additives.
Working conditions and performance requirements:

-Speed and load: The speed of medium-speed diesel engine is generally 300-1000 rpm, and the load is high. This requires that the engine oil can maintain good lubrication performance at high temperature and high pressure, form a stable oil film and reduce parts wear.

-Combustion environment: high temperature and acidic substances will be produced during combustion, so the engine oil should have good oxidation resistance and alkali value reserve to resist oxidation, neutralize acidic substances, and prevent corrosion of parts and sludge formation.

Performance characteristics:

-Appropriate viscosity: It has moderate viscosity and can quickly reach all lubricating parts under different working conditions, which not only ensures the lubrication effect, but also reduces the energy loss.

-Good detergency and dispersibility: It can effectively disperse impurities such as combustion products and wear particles, prevent them from accumulating to form sludge and carbon deposits, and keep the engine clean.

-Good anti-wear performance: it contains anti-wear additives, which can form a protective film on the metal surface, reduce the wear between friction pairs and prolong the service life of the engine.

Scope of application:

Mainly used in all kinds of medium-speed diesel engines, such as those used in ships, generator sets, railway locomotives and other fields. The performance requirements of engine oil will be different in different application scenarios. For example, marine medium-speed diesel engine oil should also have good water separation performance and anti-emulsification performance to adapt to the working environment where marine engines may come into contact with water.
