What is engine oil emulsification?

[LeAsher]

Engine oil emulsification is caused by water entering the oil. The reasons for water entering the oil are: 1. Cracked water cavity in the heat exchanger causing water to leak into the oil; 2. Poor sealing of the cylinder head or cracked water cavity, poor sealing of the cylinder liner water jacket, cylinder liner cavitation, allowing water from the combustion chamber to enter the oil. The strength of the oil film in emulsified oil decreases, making it unable to meet the lubrication requirements of the engine, necessitating replacement. The solutions for engine oil emulsification are: 1. Clean the engine and replace the oil; 2. Clean the air filter chamber, exhaust pipe, carburetor, and exhaust joint; 3. Fill the engine with kerosene, repeatedly start and shut it off, ensuring the burning time does not exceed 30 seconds, then replace with new kerosene.
