What is Oil Burning?
2 Answers
Oil burning refers to the phenomenon where engine oil enters the combustion chamber of the engine and mixes with the fuel-air mixture to burn, producing blue smoke that exits through the exhaust pipe. The following are symptoms of oil burning in a car: 1. Blue Smoke Emission: The most obvious sign of oil burning is the emission of blue smoke from the exhaust tailpipe, accompanied by a noticeable increase in oil consumption, requiring frequent oil top-ups in a short period. 2. Increased Carbon Deposits: Oil burning leads to an accumulation of carbon deposits in the combustion chamber, resulting in reduced fuel economy, decreased engine performance, and excessive exhaust emissions. The causes of oil burning are as follows: 1. Poor Fuel Quality: Low-quality gasoline can lead to carbon deposits, causing the piston rings to become stuck with carbon and preventing them from scraping oil off the cylinder walls, leaving oil in the cylinder. 2. Clogged Oil Passages: Blocked oil return holes prevent oil from returning normally to the crankcase.
Oil burning refers to the unintended entry of engine oil into the combustion chamber during the operation of a car engine, where it gets burned along with gasoline. This leads to excessive oil consumption, such as needing to top up half a liter of oil every 1,000 to 2,000 kilometers, accompanied by blue smoke from the exhaust pipe and a burnt oil smell. The usual causes include internal engine aging, worn piston rings, or scratches on the cylinder walls, allowing oil to sneak into places it shouldn't be. Some turbocharged cars may also burn oil if their seals fail. Drivers may notice reduced power, increased fuel consumption, and louder engine noise. During every maintenance check, I pay special attention to the oil dipstick and spark plugs because neglecting this issue can accelerate engine failure, potentially costing thousands to repair. Regular oil changes using the correct type can significantly prevent this problem.
