What Causes Oil Leakage in Diesel Engine Turbochargers?

[SimonFitz]

The reasons for oil leakage in diesel engine turbochargers are as follows: 1. If the vehicle has been driven for more than 100,000 kilometers or over two years, it is due to normal wear and component aging. 2. If the vehicle has only run about 10,000 kilometers and frequently operates on highways or long distances, the issue arises from a lack of understanding about turbocharged engines. Often, the engine is turned off immediately after high-speed driving, which is the most undesirable practice for turbocharged engines. Additional Information: Turbocharger: 1. It utilizes the exhaust gases from the exhaust pipe to drive the turbine at high speeds, simultaneously rotating the compressor impeller via the rotor shaft. The speed can reach 50,000 to 230,000 rpm. The high-speed rotation of the compressor impeller pressurizes the intake air, significantly increasing the air density entering the cylinders and thereby enhancing the diesel engine's power. 2. The turbocharger is a crucial component for increasing engine power and reducing exhaust emissions. Due to improper use, maintenance, and care, malfunctions can occur, leading to abnormal engine operation.
