Advantages of Sulfurized Alkyl Phenate Detergents

Superior Acid Neutralization: They efficiently neutralize corrosive combustion by-products (like sulfuric acid) to prevent premature engine wear and metal degradation.

 

High-Temperature Detergency: They are highly effective at suppressing and dissolving carbon deposits in the top ring grooves of pistons, especially in supercharged diesel engines.

 

Outstanding Antioxidant Capacity: Unlike traditional detergent alternatives, the phenolic structure provides inherent oxidation-inhibiting capabilities, prolonging the life of the lubricant.

 

Corrosion & Rust Protection: By forming a protective film and suspending acidic contaminants, they protect sensitive engine metals (such as lead and copper) from rusting and corrosive wear.

 

Good Alkali Retention: They maintain their Total Base Number (TBN) effectively over extended service intervals, making them a cornerstone additive for severe-duty marine and heavy-duty engine oils.

Application of Sulfurized Alkyl Phenate Detergents

 

 

Marine & Large Stationary Engines

Widely used as a primary additive in marine cylinder lubricants due to their exceptional alkali (base) retention and water-separation capabilities. They neutralize strong acids formed by high-sulfur fuels.

 

Heavy-Duty Diesel Oils

Utilized in crankcase oils to prevent piston ring sticking and minimize carbon deposits in high-temperature piston top ring grooves.

 

Automotive & Industrial Lubricants

Act as an anti-wear and anti-corrosive agent in internal combustion engine oils, hydraulic fluids, and industrial gear oils.
