What is the mesh guard in a car
The underbody protection device of a vehicle, commonly known as the automotive guard plate, is a crucial safety component. This type of protective plate is made of durable materials such as plastic, rubber or metal, and is designed to resist potential damage to the important components at the bottom of the vehicle caused by gravel, soil, puddles and other obstacles on the road surface.
The multiple functions carried by the car body guard include the following points:
First of all, it provides solid protection for the engine and transmission system. This means that during vehicle operation, the guard plate can absorb the impact force from road debris, obstacles and puddles, thereby ensuring the safety and damage of core components such as the engine, transmission and drive shaft.
Secondly, the guard plate helps to reduce wind resistance and noise. By optimizing the airflow at the bottom of the vehicle, the guard plate can reduce wind resistance during driving, thereby lowering the noise generated by air flow and providing a quieter and more comfortable driving environment for drivers and passengers.
Furthermore, the guard plate also plays a positive role in improving fuel economy. By improving the aerodynamic performance at the bottom of the vehicle, the guard plate helps reduce air resistance, thereby enhancing the fuel utilization efficiency to a certain extent.
In addition, the guard plate also undertakes the important task of protecting the chassis and the bottom pipes. It can effectively prevent the gravel, soil and puddles on the road surface from causing damage to these key parts, ensuring the overall structure and performance stability of the vehicle.
It is worth noting that the guard plates equipped on different vehicle models and types of cars may vary in design and materials. Some vehicles may only have guard plates installed in the bottom part of the area, while others may be equipped with more comprehensive protection systems. For consumers who want to know the details of the body guard plate of a specific vehicle model, it will be a wise choice to consult the vehicle user manual or consult the car manufacturer or dealer.
The main functions of car body guards are as follows:
Protecting the engine oil pan: The engine guard plate can effectively protect the engine oil pan and prevent it from being impacted by flying sand and stones. For tough off-road vehicles, the iron guard plate is more important, while the rear guard plate is mainly used to protect the oil pan.
Preventing foreign objects from splashing into the engine: When driving on unpaved roads, especially on muddy roads in rainy days, without the protection of the engine guard plate, soil is very likely to splash into the engine compartment, affecting the operation of the belt and making the engine compartment even dirtier and more messy.
Reducing wind resistance: The protective plates at the bottom of the car can reduce the turbulence at the bottom of the vehicle, lower the wind resistance coefficient, enhance the stability and performance of the car, and reduce fuel consumption.
Overall, car body guards play a significant role in protecting the engine, reducing the entry of foreign objects into the engine compartment, and lowering wind resistance. Whether it's a tough off-road vehicle or an ordinary SUV model, the engine guard plate is an indispensable piece of equipment. If your car does not have a guard plate, it is recommended that you install it as soon as possible to ensure driving safety and the normal operation of the engine.
When the computer board of a car malfunctions, repair personnel usually encounter some difficulties. First of all, they dare not easily determine whether the problem lies with the computer board, because the price of the computer board is relatively high, so they dare not easily decide to replace it. Secondly, even if similar computer products are found, it is very difficult to conduct substitution tests because the damage of computers is often caused by external circuit faults. Therefore, the repair personnel need to take some measures to solve this problem.
First of all, the repair personnel need to conduct a comprehensive inspection of the car's circuits to determine the specific cause of the fault. If it is found that the problem lies with the computer board, you can consider replacing it. However, since the price of the computer board is relatively high, the repair personnel need to carefully assess whether it is worth replacing. If the computer board cannot be repaired, you can consider buying a new one to replace the original one. However, before purchasing a new computer board, the repair personnel need to ensure that the computer board is compatible with other components of the vehicle and can work properly.
In addition, repair personnel can also attempt to fix the faults on the computer board. This requires them to have certain knowledge and experience in electronic technology. They need to determine the type of fault first and then find the corresponding solution. For example, if the fault is caused by a short circuit in the circuit, the repair personnel need to fix the circuit to ensure that the computer board can work properly. If the malfunction is caused by software issues, the repair personnel need to reinstall the software or carry out software fixes.
In conclusion, repairing faults in a car's computer board requires the repairman to have certain skills and experience. If the repairman is unable to solve the problem, it is recommended to send the vehicle to a professional auto repair shop for maintenance. During the maintenance process, the repair personnel should follow the safety operation procedures to ensure that the repair process does not cause further damage to the vehicle.
