What are the reasons for the loud noise in Wuling Hongguang?

[VonHarrison]

Wuling Hongguang may produce loud noise due to poor fuel quality, detonation or knocking phenomena, and structural noise of the vehicle. The specific reasons are as follows: Poor fuel quality: If the fuel quality of the car is poor, it will cause problems in the internal combustion of the engine. This leads to severe engine vibration and increased noise. Additionally, it can result in more carbon deposits and higher fuel consumption. Therefore, it is essential to use high-quality fuel for the car. Detonation or knocking phenomena: This usually occurs when the spark plug ignites, and the remaining combustible mixture at the end undergoes spontaneous combustion. At this point, the flame ignited by the spark plug and the flame formed at the end propagate in opposite directions at an impact speed, producing a sharp and harsh knocking sound, which increases the car's noise. Structural noise of the vehicle: The structural noise of the car mainly comes from vibration transmission and the vibration of metal components under force, which is relatively normal and not considered a fault of the car.
