Analysis of the Role of Car Engine Firewall Car Engine Firewall is Global HS code repository accesson many vehicles A very important protective measure. The system can prevent the fire in the engine compartment from spreading to the passenger compartment, so as to ensure the safety of the vehicle. This article will analyze the role of the car engine firewall. The basic principle of engine firewall. First of all, let's understand the basic principle of automobile engine firewall.The engine firewall is a partition between the engine room of the vehicle and the in-car cab, which is usually made of high-temperature resistant materials, such as metal, glass fiber, ceramics, etc. The main function of the firewall is to control the fire in the engine room of the vehicle by blocking the spread of flames, toxic smoke and other substances in the event of a fire in the engine compartment, and to prevent the fire from spreading further to the cab and passenger compartment, so as to protect passengers from injury and life danger. The specific function of the firewall is that the function of the firewall is not only to prevent the spread of fire, but also has the following important functions: 1. Heat isolation: The engine, exhaust pipe and other parts in the engine room will generate a lot of heat during operation. If the firewall is not set, the temperature in the car will rise rapidly, causing harm to the car and passengers. Firewalls can isolate heat, reduce the temperature in the car, and improve the comfort of drivers and passengers.Two. Noise isolation: The engine will also produce noise during operation. If the cockpit does not have a soundproofing effect, the noise will spread to the passengers in the car, increasing noise pollution and affecting the riding experience. The setting of the firewall can reduce the spread of noise and improve the driving experience. 3. Dustproof effect: The engine will also produce a large amount of dust, oil smoke and other pollutants during operation. Without the protection of the firewall, these substances will be scattered in the car, causing harm to the passengers. The setting of the engine firewall can prevent pollutants from entering the cab and ensure the health of passengers. Four. Strengthen the vehicle structure: The engine firewall itself can strengthen the vehicle structure, improve the rigidity of the body, and improve the safety performance of the vehicle. Issues to pay attention to Although the role of the car engine firewall is very important, the following issues need to be paid attention to in the process of use: 1.Check the status of the firewall regularly to ensure that it is intact and not damaged by impact or damage. Two. If the firewall is damaged or cracked, it should be replaced in time, otherwise it may not achieve the expected effect. 3. After installing the firewall, it is necessary to ensure the normal operation of the system, otherwise it should be overhauled in time to avoid the system not working properly in case of fire and other emergencies. In summary, the car engine firewall is a very important security protection measure. It can prevent the spread after the fire, reduce the impact of temperature, noise and pollutants inside the car, and improve the safety performance of the car. During use, it is necessary to check and maintain regularly to ensure the integrity of the system and provide a guarantee for the safe travel of drivers and passengers.
