How to solve the problem of corrosive wear in engine oils?

 Fuel (especially diesel and heavy fuels) produces sulfur and nitrogen oxides during combustion, which enter the engine oil and form strong acidic substances such as sulfuric acid and nitric acid.

TBN400 calcium sulfonate is a highly alkaline detergent with a large alkaline reserve (TBN up to 400 mg KOH/g). These alkaline substances can continuously and efficiently neutralize the acidic substances produced, preventing them from corroding the precision metal components inside the engine, such as bearings, piston rings, cylinder liners, etc., thereby significantly reducing corrosive wear.

TBN400 calcium sulfonate is mainly used in fields that require extremely strict lubricating oil requirements, such as marine engines. Marine fuel oil has a very high sulfur content and produces a lot of acidic substances. This ultra-high alkali value additive must be used to protect the engine.

What if effective measures are taken to prevent carbon buildup and sludge in engine oil?

Image
Engine oil will be oxidized at high temperatures, and incomplete combustion of fuel will form soot and resin like substances. These substances will gather together to form carbon deposits (in high-temperature areas) and sludge (in low-temperature areas). TBN400 calcium sulfonate is a commonly used cleaning agent for engine oil, which can "clean" the carbon deposits and paint films that have already formed on high-temperature engine components (such as piston ring areas and piston top banks) and disperse them in the engine oil. At the same time, TBN400 calcium sulfonate can wrap small solid particles such as soot and sludge in the engine oil, preventing them from aggregating and depositing with each other, thus maintaining the cleanliness of the engine interior. This is crucial for diesel engines that operate for long periods of time or under harsh conditions, as it can effectively prevent problems such as piston ring jamming and oil circuit blockage. https://adhtchem.com/prod...
