If there is no engine compartment soundproofing foam, will it cause more noise?

When it comes to the reduction of the car, I believe that many car owners are nervous, many models in the introduction of China will be more or less reduced, today less configuration, tomorrow the seat is replaced with weaving, these usual tricks have long been familiar to everyone. Today's configuration you may not have cared about,That is, soundproof cotton,Generally, everyone's attention is focused on the security configuration and similar to the central control screen,There are really not many people who care about soundproof cotton。

The reduction of soundproof cotton generally occurs in the most inexpensive family cars, but it is not entirely, even luxury brands will still take into account the cost factor and reduce the configuration, but in many cases, the corresponding bayonet is reserved on the hood, the owner can buy it online, and the installation is very simple, but the specific effect is not known. Although it is said to be soundproofing cotton, soundproofing is only a small part of it, and there are many other uses. 1.

Reduce the impact of high engine temperature on the paint surface When the car opens the cabin after driving for a period of time, a burst of heat hits the face, and the engine working temperature has not been dissipated in the cabin, and this heat will have a great impact on the paint of the cabin cover, and it will lose its luster and age over time. At this time, the sound insulation cotton can be a good heat insulation and protect the car paint.

Secondly, in the cold winter, the soundproof cotton can also protect the heat of the engine from dissipating quickly, and the engine temperature will drop quickly after a short period of flameout, which is very friendly to start here. 2.Soundproof and soundproof cotton can reduce the engine noise entering the cab to a certain extent, about only a few decibels, but don't underestimate the noise of these few decibels, it has a great effect on improving the comfort of driving.

So some people ask, since it is soundproof cotton, will spontaneous combustion occur? It's really unnecessary to worry about this, because the materials of soundproof cotton are made of flame-retardant materials, unless you are buying some inferior products without quality assurance, and the reason why the engine can be cooled down, mainly depends on the cooling system to achieve, if the water temperature of the car is too high, it is definitely a problem with the cooling system, and it will definitely not be a pot of soundproof cotton, and you can't rely on the heat insulation cotton.

<> from the above description, we can also see that the real role of soundproof cotton is not to reduce the sound and noise of the car, but to play a role in heat insulation and heat preservation, and to protect the engine of our car. If you still haven't installed soundproof cotton for your car, we might as well buy a piece and install it for a period of time, in addition to sound insulation, its role is still very large. We can't simply assume that just because it's called soundproofing cotton, it can only play the role of soundproofing.

If the engine does not have sound insulation cotton, it will lead to increased noise in the car space, and the sound insulation cotton can absorb and digest the noise generated by the engine well, and can provide a quiet environment for the cab.

Without the engine compartment soundproofing cotton, it will cause increased noise, and coupled with the tire noise, the sound inside the car can be said to be a symphony.

Useful, the heat-insulating cotton of the hood must be made of good materials, and the door can also be properly soundproofed, which can be matched with sound-absorbing cotton, and other problems can be raised at any time.

There must be a role, but it's hard to say how useful it is.

When it comes to under-knitting cars, I'm sure that in China, many car owners will be worried about replacing them with fewer seats. The configuration we are discussing today may not be of concern, and that is soundproofing cotton. In general, everyone's attention is focused on the security configuration and similar large** control screens.

Not many people really care about soundproof cotton. The partition between the engine compartment and the cockpit is called a firewall and separates the engine from the cockpit. However, the firewall is just a steel plate that cannot prevent noise and heat from entering the cockpit in the cabin, so thermal and acoustic insulation is required.

Typically, the firewall on the other side of the engine compartment will be covered with thermal and acoustic insulation and the exterior will be covered with aluminum foil to reflect the thermal radiation of the engine. The interior is made of foam material to reduce vibration and sound insulation. The reduction in sound-insulating cotton usually occurs in low-cost family cars, but not completely.

Considering the cost factor, even luxury brands will reduce their allocation. However, in many cases, the corresponding bayonet was retained on the bonnet, which the owner could buy online. The installation is also simple, but the exact effect is unknown.

Although it is soundproofing cotton, it has little soundproofing effect and has many other uses. 1.Reduces the impact of high engine temperatures on painted surfaces.

When the engine compartment is opened after driving for a while, there is a stream of heat hitting the face. The operating temperature of the engine cannot be dissipated in the engine compartment. This heat can have a big impact on the paint of the engine compartment cover, which can lose its luster and age over time.

At this time, the soundproof cotton can insulate the heat well and protect the car paint.

The cheapest soundproofing cotton is generally used on the firewall in the car, which is a thick cotton felt pad pressed from various fibers and wool leftovers, which mainly plays a role in sound insulation. In the image above, the car can be faintly seen behind the pedals. It is basically the same as the cotton pad that is used to protect the furniture when it is pulled.

Many cars use this material. Secondly, in the cold winter, the soundproof cotton can also protect the heat of the engine from being quickly dissipated. After a short stall, the engine temperature does not drop quickly, so starting here is very friendly.

2.Acoustic insulation foam can reduce engine noise in the cab to a certain extent, only a few decibels, but don't underestimate these decibels. It plays a big role in improving driving comfort.

Without the engine rubbing the sound insulation cotton, it may increase the noise, because the sound insulation cotton can effectively prevent the engine from producing excessive sound, can ensure that the state of the engine is more stable, and the engine may have a loud sound when accelerating after dismantling.

In the process of engine production, the cabin soundproofing cotton is very important, if this soundproofing cotton is missing, the noise of the engine will increase. It also increases wear and tear.

The noise will increase because the effect of this soundproof cotton is very good, and if you don't have it, the vibration of the engine will be particularly strong.

Engine compartment sound insulation cotton effect: 1. Generally, the material of engine compartment sound insulation cotton is flame retardant, or very effective sound insulation, absorbing some noise, effectively slowing down the vibration of the body, eliminating the fatigue of the body metal, and also has a certain anti-rust effect of Ying Zheng, heat insulation and thermal insulation can effectively protect the cover, so the sound insulation cotton still has a certain effect;

2. First of all, the effect of this protective cotton on the temperature isolation is quite obvious, in other words, because of the existence of the thermal insulation cotton, to a certain extent, it can protect the rapid aging of the paint on the surface of the engine compartment cover;

3. Secondly, the insulating cotton can protect the temperature in the cabin from rapid loss, especially in winter, after having the insulating cotton, even in cold weather, the temperature in the cabin will not drop sharply, so as to reduce the damage to the engine when starting again in a short time;

4. Finally, many people will wonder if there is a risk of spontaneous combustion or damage to the engine because the temperature in the cabin is not dissipated after the installation of heat insulation cotton? In fact, there is no need to worry about this, first of all, the qualified sound insulation cotton must be flame retardant, unless you buy counterfeit and shoddy products, and moreover, the engine cooling is mainly achieved through the cooling system, if you find that the water temperature rises then it is definitely the cooling system problem, not the fault of the insulation cotton.

Millions of car purchase subsidies.

Hazards of Engine Sound Insulation Cotton The Hazards of Engine Sound Insulation Cotton Engine sound insulation cotton is mainly to reduce the spread of noise, and its main hazard is that it will cause excessive temperature. Engine hood soundproof cotton has a certain effect on the vehicle: 1. Noise insulation, hail sound, flame retardant, generally speaking, the soundproof cotton material is a flame retardant design, and the sound-absorbing effect is attached to the body, which can effectively slow down the body vibration and eliminate the body metal fatigue; 2. The waterproof performance of soundproof cotton can effectively eliminate the contact between water vapor and the metal of the door panel, and play a role in preventing rust; 3. Heat insulation, protect the paint of the engine cover, avoid the high temperature of the engine directly to the cover, so as to protect the paint cover, and at the same time avoid fogging the cover and affecting the line of sight in rainy days.

If the car engine is noisy, it is still necessary to install engine sound insulation cotton, which can reduce the noise of the car to a certain extent. Acoustic insulation cotton has a good thermal insulation effect, and after being pasted in the hood of the car, it can effectively prevent the high temperature of the engine from being transmitted directly to the hood, so as to protect the paint on the surface of the hood.

For the noise of the vehicle engine, many manufacturers install soundproofing cotton to reduce noise, and install soundproof cotton in the engine compartment firewall and other parts to absorb the energy generated by the noise and convert it into heat energy to dissipate into the atmosphere; In addition, the installation of soundproof cotton at the engine compartment firewall is required to disassemble a large number of cabin parts and pipelines, and it also requires a certain theoretical knowledge of the car.

The presence of thermal insulation cotton can protect the paint on the surface of the engine compartment cover from rapid aging to a certain extent, and the thermal insulation cotton also prevents the cabin temperature from dissipating quickly, and the temperature in the cabin will not drop sharply even in cold weather in winter, thereby reducing the damage to the engine when starting again in a short time.

Soundproofing cotton is not the danger of spontaneous combustion or damage to the engine because the temperature in the cabin is not dissipated, because qualified soundproofing cotton must have flame retardant conditions, unless some counterfeit and shoddy products on the market; Secondly, the cooling of the engine is mainly done through the cooling system, and when the water temperature rises, the cooling system fails, and it is not the heat insulation cotton. Therefore, in addition to inferior counterfeit products, the installation of soundproof cotton has a great effect on the vehicle itself.

If there is noise in the car engine, it is still necessary to install engine soundproof cotton. These modifications can reduce interior noise to a certain extent. Acoustic insulation cotton has a good thermal insulation effect, which can effectively prevent the high temperature of the engine from being transmitted directly to the hood, thereby protecting the surface paint of the hood.

In view of the noise of the vehicle engine, many manufacturers reduce the noise by installing soundproof cotton, and install soundproof cotton in the engine compartment firewall and other parts to absorb the energy generated by the noise and convert it into heat energy to dissipate into the atmosphere. In addition, the installation of soundproof cotton at the engine compartment firewall requires the removal of a large number of engine compartment parts and pipelines, and also requires a certain amount of automotive theoretical knowledge, so it is not recommended that some car owners install it themselves in the future.

The presence of insulation cotton can protect the paint on the surface of the engine hood from aging rapidly to a certain extent, and at the same time, the insulation cotton can also prevent the temperature in the cabin from dissipating quickly, even in the case of cold winter weather, the cabin temperature will not drop suddenly, thereby reducing the damage to the engine when restarting in a short time.

Soundproofing cotton will not have the risk of spontaneous combustion or engine damage because the temperature in the cabin cannot be dissipated, because qualified soundproofing cotton must have flame retardant conditions, unless there are some counterfeit and shoddy products on the market; Secondly, the cooling of the engine is mainly done through the cooling system. When the water temperature rises, the cooling system fails, not the insulating cotton. Therefore, in addition to inferior counterfeit products, qualified products also have a great impact on the vehicle itself.
