What if the engine is DigiPlusloud? - How to reduce the volume of the engine? When driving, the sound of the engine is inevitable. However, in some cases, the engine sound is too loud, which not only affects the driver's mood and safety, but also interferes with pedestrians and the surrounding environment. So, what should you do if your vehicle causes noise and pollution? In this article, we will discuss several ways to reduce engine noise. 1. Replace the silencer. First of all, you can replace the silencer. The silencer is an important component of the engine exhaust system, which can reduce exhaust noise and environmental pollution. There are generally two types of silencers: straight-through and reflective. The pass-through silencer can improve the exhaust efficiency, but it will increase the noise.The reflective silencer can block noise waves, but it will reduce the exhaust volume. According to the different types of vehicles and driving needs, you can choose a suitable silencer. Two. The second way to replace the engine and transmission bracket is to replace the engine and transmission bracket. The function of the engine and transmission brackets is to reduce vibration and noise. If these brackets fail, the engine noise will become more obvious. In order to reduce noise, you can replace the damaged bracket with standard original accessories. 3. The third way to install soundproofing materials is to add soundproofing materials during the daily maintenance of the vehicle. Soundproofing materials can reduce the noise in the car and the engine room, which is good for the environment and passengers. Common soundproofing materials include soundproofing blankets, waterproof membranes, thermal insulation paper, etc. These materials can not only reduce noise, but also effectively reduce the temperature in the car and improve driving comfort.Four. The fourth way to keep the engine clean is to keep the engine clean. By regularly changing car oil, cleaning the engine and other maintenance measures, friction and wear can be reduced, thus reducing the noise of the engine. In particular, the corrosion, scale accumulation and corrosion of the exhaust pipe are important factors for noise increase. Therefore, doing a good job in car maintenance is an important prerequisite for reducing noise. 5. Reduce the driving speed. Finally, reducing the driving speed is also a simple way to reduce engine noise. When driving at high speed, the engine will produce higher speed and noise, especially when starting. When slowing downhill, the speed decreases, the engine load decreases, and the noise decreases accordingly. It is very necessary to adjust the speed reasonably during the driving process. In a word, reducing engine noise is not only good for the owner himself, but also reduces the interference of noise to the surrounding environment.To reduce engine noise, it can be achieved by replacing the silencer, replacing the engine and transmission bracket, adding soundproofing materials, maintaining cleanliness and reducing the speed. Any method needs to be adapted to the vehicle, so you should consult professional technicians for advice before repair and maintenance.
