How to Reduce Noise in Wuling Hongguang S?
3 Answers
Methods to reduce noise in Wuling Hongguang S are as follows: 1. Install sound-absorbing foam. Function: Mainly used to deal with engine noise. If the engine sound is too loud, you can paste an advanced sound-absorbing foam material under the engine hood, which can not only absorb and consume a large amount of engine noise but also suppress the vibration of the engine hood. 2. Apply sound-absorbing cotton. Function: Mainly used to deal with trunk noise and door noise. For the engine, sound-absorbing foam is installed, while for the trunk, sound-absorbing cotton can be tried. Installing sound-absorbing cotton material at the bottom of the trunk and on the wheel arches on both sides of the trunk can effectively reduce tire noise, road noise, and noise from the exhaust system. Reasons for noise in Wuling Hongguang S: 1. Carbon deposits in the car. Any car will have carbon deposits, no matter how good the driving skills are or how good the road conditions are. Because gasoline contains colloids, impurities, etc., impurities in the air mixed with oil vapor form carbon deposits on the throttle valve and intake tract. Carbon deposits in these two places will affect the smoothness of air intake, and carbon deposits in the cylinder will directly affect the combustion effect, even causing detonation and knocking, increasing noise. 2. Wear of some moving parts, wear of ball joints, loosening of clips, etc., all lead to excessive gaps, resulting in slight impacts during operation and increased noise.
I've been repairing cars for over ten years, and the main sources of noise in the Wuling Hongguang usually come from the engine, tires, and loose interior parts. High engine noise could be due to old belts or dirty oil—it's recommended to change the oil and filter regularly, and using synthetic oil can make it quieter. Noisy tires are annoying; switching to a set of low-rolling-resistance quiet tires, like Continental or Giti's budget-friendly options, can cut road noise in half. Interior rattles are common—stuff some soundproofing foam behind the door panels and under the dashboard. You can buy the materials and DIY for just a few dozen bucks, with immediate results. Check the chassis guard and exhaust pipe brackets—tighten any loose bolts to reduce vibration noise. With these small upgrades, the car will become much quieter, making long drives way more comfortable.
I've been driving this car for over five years and have dealt with quite a few noise issues. Reducing the RPM is key—keeping the speed under 80 km/h significantly cuts down wind noise. Tires are crucial; the stock ones are noisy, but switching to quiet tires like Michelin Energy Saver makes a noticeable difference. For the interior, adding a non-slip mat in the trunk when loading items reduces rattling. Driving habits matter too—avoid sudden acceleration to keep the engine running smoothly. Aging seals can let in wind; buying new rubber seals from Taobao is a cheap and effective fix. Regularly check tire pressure—softer tires mean less noise. These small adjustments add up to a quieter and more comfortable ride.
