What are the consequences of burning engine oil?
1 Answers
Burning engine oil can lead to several consequences, including incomplete combustion in the engine's combustion chamber, which increases carbon deposits and reduces the vehicle's power performance. It also results in higher fuel consumption and more severe exhaust emissions, potentially exceeding pollution standards, thereby increasing the owner's financial burden. Additionally, carbon buildup can cause the piston rings to seize, losing their oil-scraping function and exacerbating the oil burning issue. Causes and solutions for engine oil burning: Front and rear crankshaft oil seal aging: The front and rear crankshaft oil seals are in continuous and extensive contact with oil. The impurities in the oil and the constant temperature changes within the engine gradually weaken their sealing effectiveness, leading to oil seepage or leakage. In this case, the front and rear crankshaft oil seals need to be replaced. Excessive piston clearance: Carbon deposits can enlarge the gap between the piston rings and the cylinder, allowing oil to enter the combustion chamber and causing oil burning. This situation requires cleaning the carbon deposits, reducing the piston clearance, or replacing the pistons. Clogged air filter: A clogged air filter can obstruct airflow, reducing intake pressure and creating a vacuum that draws oil into the combustion chamber, leading to oil burning. In this case, the air filter needs to be cleaned.
