What Causes Oil Emulsification?
1 Answers
Oil emulsification refers to the phenomenon where engine oil mixes with water or gasoline, resulting in a milky yellow or milky white appearance. The following are the related causes of oil emulsification: 1. Prolonged low-temperature operation of the engine: When the engine runs at low temperatures, the fuel injected into the cylinders may not burn completely. Some gasoline adhering to the cylinder walls can flow into the crankcase and then enter the oil pan, mixing with the oil and causing emulsification. 2. Internal corrosion of the oil cooler: If the oil and coolant passages are interconnected, the mixing of coolant and oil can lead to oil emulsification. 3. Damage to the cylinder head gasket: The cylinder head gasket is installed at the junction between the cylinder head and the engine block, connecting the coolant, air, and oil passages. If the gasket is damaged, coolant can enter the oil passages, resulting in oil emulsification.
