Where is the car firewall

1. The firewall of the car is between the engine compartment and the cockpit. You can see it after opening the engine cover. There is an iron plate under the windshield, which separates the engine compartment from the cockpit. This iron plate is the firewall.

2. The firewall is located in the engine compartment. You can see the firewall after opening the engine cover. A firewall is a layer of iron between the engine and the cockpit, which is usually covered with thermal insulation.The firewall can prevent the fire from spreading to the cockpit after the engine compartment catches fire.

3. The firewall is located in the engine compartment, and it can be seen when the engine hood is opened. It is a layer of iron plate to prevent the fire from spreading from the engine compartment to the cockpit. Most iron plates can be covered with thermal insulation materials to prevent high-temperature burning. There are many wires and plugs in the engine compartment, so do not use a high-pressure water gun when washing the car to avoid short circuit.

4. The firewall is located in the engine compartment, which can be seen when the engine hood is opened. It is a layer of iron plate between the firewall engine and the cab, which can be mostly covered with thermal insulation material. The firewall can prevent the fire from spreading to the cockpit after the engine compartment catches fire.

What is the function of the engine firewall

The firewall can prevent the fire from spreading to the driving compartment after the engine compartment catches fire. After opening, you can see a large black disc under the windshield. This large disc is a vacuum booster pump, and this large disc is fixed to the firewall.

The function of car firewall: to increase the safety of car passengers and drivers. In the car, the firewall is used to separate the passenger from the engine so that once the car engine catches fire, the firewall can not only protect the safety of the passenger but also allow the driver to continue to control the engine.

Firewall Module is an important part of the Volvo XC60 vehicle electronic system. It is located in the engine compartment and mainly plays the role of fire prevention and isolation.

The firewall can prevent the fire from spreading to the cockpit after the engine compartment catches fire. After opening the engine cover, you can see a large black disc under the front windshield. This large disc is a vacuum booster pump, and this large disc is fixed to the firewall.

It is the fireproof material inside and outside the front enclosure. In the process of driving for a long time, the car engine will inevitably produce high temperature, which is easy to cause spontaneous combustion of the car, etc., causing safety hazards to car passengers. Then the birth of the car firewall greatly increases the safety of car passengers and drivers.

1. The firewall is located in the engine compartment, and you can see the firewall after opening the engine cover. The firewall is a layer of iron plate between the engine and the cockpit, which is usually covered with heat-insulating materials. The firewall can prevent the fire from spreading into the cockpit after the engine compartment catches fire.

2. The firewall is located in the engine compartment. You can see the firewall after opening the engine cover.

13 What is a hole in the Baolai engine firewall for

1. This is generally a screw hole reserved for other functions or equipment, which is normal. Basically, all machines need to Yes, for example, your and my cars are the same model, and mine is the standard one. And yours is a high configuration, so I have more idle screws than you.

2. The exhaust hole of the Baolai automatic transmission is in the following position of the engine, and it is covered on the gearbox. All the gearboxes are available.The ventilation hole is used to remove the pressure caused by the change of temperature difference. The ventilation hole is located in the upper part of the gearbox. When the water level exceeds the middle line of the wheel or the water surface fluctuates, there is a possibility of water inlet.

3. The front fender of the model Baolai needs to be modified, mainly because there may be some shortcomings in the design and production process of the vehicle. By modifying the front fender, the performance and aesthetics of the vehicle can be improved.

4. This is the forced ventilation valve of the crankcase. Its function is to isolate the liquid oil in the excess exhaust gas in the crankcase and introduce the exhaust gas into the front of the intake valve. Hope to adopt.

5. Engine compartment drainage hole: the rear of the engine compartment, the lower edge of the windshield, air intake; air and water adjustment drainage hole: located below the chassis.

How to soundproof the engine firewall

The noise and vibration generated by the engine operation can be blocked by pasting sound insulation materials in the U-shaped groove, firewall and bottom plate. Engine cover and firewall sound insulation can choose aluminum foil soundproofing and vibration damping plate combined with aluminum foil soundproofing cotton or aluminum foil sound-absorbing cotton, which are all good soundproofing materials.

Method 1: Install sound-absorbing foam Function: It is mainly used to deal with engine noise. If you feel that the engine is too loud, you can paste an advanced sound-absorbing foam material under the engine cover, which can not only absorb and consume a large amount of engine noise, but also suppress the vibration of the hood. This is also the method that most people will choose.

First, cut the sandwich cotton, brush the glue, and then paste it on the surface of the original car insulation pad.After the sandwich is full, brush the glue for sound insulation and heat and paste it on the surface of the sandwich cotton. After the sound insulation and heat-insulating cotton is full, press the material by hand, and the construction is completed.
