Is it necessary to install the engine guard? This question has also been asked by myself. The final conclusion is that it is necessary to install it. I personally felt that it was necessary for me to scrape the chassis a few times after installing a steel guard plate on the car. If so, this article will not have to be written, nor will there be so many people questioning the need for engine guards. Therefore, it is still necessary to talk about engine guards.
â— In the end do you want to install the engine guard?
This problem can be divided into two factions: not loaded and loaded.
People who don’t install say that engine guards are not available in the original factory. Why do we have to install them? Engineers in automotive design have had full consideration and do not install them. We don’t need to worry about them. Mounting the shield will increase body weight and affect vehicle performance. And in the event of a vehicle collision, installing engine guards will affect the sinking of the engine, affecting the vehicle's energy absorption, and endangering the lives of the crisis; adding sources of abnormal noise to the vehicle.
In the eyes of non-installed people, it is always possible to find a reason not to install. For those who need to install, one reason is enough. I am one of them.
My car modified the suspension and the spring. The height of the chassis was nearly 5cm lower than that of the original car. Therefore, I always worry that the vehicle will hit the oil pan when bumping on the bumpy road. So when I lowered the car, I immediately ran away. Special car engine guards. After bumping a few times, the engine was unscathed and good.
However, there are several factors that need to be considered when installing engine guards, such as materials, special cars, abnormal noise, and heat dissipation, depending on the needs of different people.
â— There are several factors to consider when installing the engine guard
1. What material is better
Engine protection plate material is made of aluminum alloy, resin, titanium alloy and steel plate. I bought a steel plate, which is heavier than other materials, about 2KG; and the other three are relatively lighter. Aluminum alloy shields are generally thin, such as the new Civic engine guard is aluminum alloy, very thin one, fast heat dissipation; the main role is to block the small stone strike and keep the engine clean, does not achieve a large impact protection.
Resin (hard plastic) is light and heat-dissipating is slow, but it is better than aluminum alloy. In addition to blocking the impact of small stones and keeping the engine clean, small impact can also rebound, there will be no large deformation; just face to face It still cannot effectively protect the engine against large impacts. My colleague's car was matched with a resin shield, but after hitting the big rock in the middle of the road, the transmission oil pan was still worn.
The advantages of the steel plate are cheap, and it has strong impact resistance. However, if it is subjected to a large impact, it will have a large deformation, and it will be very bulky. Titanium alloy plate is estimated to be the best, it has a strong, light weight, but it is also the most expensive.
What kind of engine protection board is selected, this can only be determined according to individual needs. When I chose, there was no resin, aluminum alloy, and only steel and titanium alloys couldn't afford titanium alloys. I had to buy steel plates.
2. Affecting engine sinking
Affecting the engine sinking, if the design of the engine guard is not scientific enough, when a collision occurs in front of the vehicle, it will actually affect the sinking of the engine, thereby affecting the safety of the people in the carriage; but at the time of purchase, if we can choose some formal, And the design of a reasonable engine guard can still effectively avoid the phenomenon of engine sinking.
Because the engine guards were also designed with this issue in mind, the guards were specially designed; some were hollowed out in the guards, leaving space for the engine to sink; some were connected to the body, the screws The hole is made into an ear-type hole, and if it breaks automatically when a collision occurs, the sinking of the engine can quickly spread the shield.
3. Affect heat dissipation
Affecting heat dissipation is also a concern for people who do not install engine guards. In fact, the engine guards are designed with many small holes. During the fast driving process, high-speed air flows from the front of the vehicle and then flows through the small holes, which does not affect the heat dissipation of the engine. How much impact.
â— Editing summary:
People who do not like to install engine guards have reasons that they do not like. The occurrence of engine failure is not something that every owner will encounter. The equipment does not contain personal wishes. However, editors recommend that models with no fenders should be equipped with a fender as much as possible, and its role is really good; however, it is necessary to find special products that are designed for exclusive use and that are designed to meet the needs of owners who do not install fenders. Heat and heavy and other hidden concerns.
