What Causes a Jinbei Vehicle to Feel Stuffy When Accelerating and Lack Power?
2 Answers
Jinbei Vehicle Feeling Stuffy and Lacking Power During Acceleration is Mainly Due to Oil Leakage. Below are the Related Causes and Solutions: 1. Oil Leakage: Turbocharger failure caused by oil leakage. Solution: First, check whether the external oil pipes of the engine lubrication system (including the turbocharger's inlet and return oil pipes) are leaking oil, and check whether there is oil at the turbocharger's exhaust outlet. If oil is present, it can be determined that the sealing ring on the turbine side is damaged and should be replaced. 2. Filter Clogging: During the process of air being sucked in by the turbocharger, the airflow encounters significant resistance (such as a clogged air filter element, or the intake hose being deformed or flattened). The pressure at the compressor's air intake is low, causing oil to leak into the compressor and enter the combustion chamber along with the compressed air to be burned. Solution: Check the intake pipe wall for oil and whether it is flattened, obstructing airflow, or if the air filter element is clogged. If there is oil at the pipe opening or wall, the air filter element should be cleaned or replaced.
My Jinbei van recently also experienced the issue of sluggish acceleration and feeling stuffy when refueling. Looking back, it was a problem with the fuel system. It could be due to an aging fuel pump not delivering enough fuel, or clogged fuel injectors causing poor atomization, preventing the engine from getting sufficient fuel. I recommend checking the fuel filter first—if it's clogged, simply replace it. Additionally, impurities in the fuel lines can also cause sluggish acceleration; try adding a fuel system cleaner. Pay attention to fuel quality when driving and avoid using low-grade gasoline to minimize such issues. It's best to replace the fuel filter every 20,000 kilometers to keep the system running smoothly, otherwise, the problem may recur. After I fixed it last time, the vehicle's power immediately recovered—simple and practical.
