What causes the loud engine noise in Xiali N5?
1 Answers
There are several reasons for the loud engine noise in Xiali N5: Excessive carbon buildup: Excessive carbon buildup in the engine is a significant cause, primarily due to the use of inappropriate fuel. Solution: It is recommended to add a certain amount of fuel cleaner during refueling. After cleaning, it's best to drive at high speed for a while, which helps increase exhaust flow and allows stronger airflow to carry out larger carbon particles. Oxygen sensor damage: The oxygen sensor mainly monitors the air-fuel ratio in the engine. Once damaged, it will cause an imbalance in the air-fuel ratio, leading to a sudden increase in fuel consumption. Solution: Check the oxygen sensor as it is an internal control unit of the car, and the oxygen sensor should be replaced.
