What Causes Engine Oil Burning in Car Engines?
1 Answers
Car engine oil burning can be caused by: 1. Using engine oil of poor quality or with viscosity grade not meeting requirements; 2. Excessive clearance between piston rings and cylinder walls, improper installation of piston rings, or deteriorated sealing; 3. Overfilling of engine oil leading to oil burning; 4. Oil leakage from turbocharger; 5. Leaking valve stem seals. Solutions for car engine oil burning include: 1. Removing the engine cylinder head to replace valve stem seals; 2. Removing the oil pan to replace piston rings. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Minimizing gas leakage and preventing contamination from external pollutants; 3. Protecting components from contact with water, air, and acidic harmful gases; 4. Buffering pressure rise at engine cylinder ports; 5. Cleaning dirt generated on component working surfaces.
