Does the Turbocharger Burn Engine Oil?
1 Answers
Under normal circumstances, the turbocharger does not burn engine oil unless there is an oil leakage issue. Below are the criteria for determining oil burning and the main causes: Criteria for determining oil burning: The "Automotive Engine Performance Test Method" (GB19055/2003) states that during full-load operation at rated speed, the engine oil/fuel consumption ratio should not exceed 0.3%. Exceeding this value can be identified as oil burning. Main causes of oil burning: Poor cylinder sealing is the primary cause of oil burning. Poor cylinder sealing is mainly due to excessive clearance between the piston and cylinder wall, improper installation or poor sealing performance of piston rings, allowing oil from the cylinder wall to enter the combustion chamber, leading to oil combustion. Additionally, poor sealing performance of the valve seal, damage to the crankcase ventilation valve, or blockage of the crankcase exhaust port can cause excessive pressure in the crankcase, allowing oil to enter the cylinder along with crankcase gases and burn.
