Why Does Engine Oil Emulsify?

[HarrisonAnn]

Engine oil emulsification is caused by water entering the oil. Below are the reasons for water ingress leading to oil emulsification and the solutions: Reasons for water entering engine oil: Cracks in the water chamber of the heat exchanger allowing water to leak into the oil; poor sealing of the cylinder head or cracks in the water chamber, inadequate sealing of the cylinder liner water jacket, cylinder liner cavitation, allowing water from the combustion chamber to enter the oil. Emulsified oil has reduced film strength and cannot meet the lubrication requirements of the engine, necessitating replacement. Solutions for engine oil emulsification: Clean the engine and replace the oil; clean the air filter chamber, exhaust pipe, carburetor, and exhaust joints; fill the engine with kerosene, repeatedly start and shut off the engine, ensuring the burning time does not exceed 30 seconds, then replace with fresh kerosene.
