What Causes Blue Smoke from China VI Diesel Vehicles?

[JosephineMarie]

Blue smoke from China VI diesel vehicles is produced when engine oil enters the combustion chamber and gets burned. Normal Engine Wear: As the engine ages, the wear between working components increases, leading to larger gaps. This reduces the sealing performance of components, allowing engine oil to leak into the combustion chamber, where it burns and produces blue smoke. Abnormal Engine Wear: During engine operation, insufficient lubrication of friction components, prolonged operation with low oil levels, failure to replace engine oil and oil filters regularly, or high-throttle operation when the engine is cold can all cause abnormal wear. This leads to oil leakage and combustion, resulting in blue smoke.
