In the early days, people's awareness of engine protection was weak, and they basically did not protect it. In order to reduce the cost of building a car, the original automobile manufacturer brought a small piece of soft plastic fender under the engine, and the coverage rate was only 15%-20%.
In recent years, while the automobile market is particularly active, car owners have realized the importance of engine protection, and a number of manufacturers of engine field protection devices have started their research and development and manufacturing.
First generation: hard plastic guard plate
The price is relatively cheap and the manufacturing process is simple, but it should be noted that the fender made of this material is easy to break down, especially in winter, and it is easy to damage itself. After it is broken, it cannot be repaired and will not play a long-term protection role.
Advantages: light weight and low price.
Disadvantages: easy to damage and age.
Engine sinking: Because this material itself is easy to break, it will generally not affect the engine sinking.
Second generation: resin guard plate
Compared with the first generation materials, although the durability has been improved, the main material is still plastic, but the consumption ratio is different in production, and the product itself is soft, which can not really play the role of collision prevention. The second generation resin material has the disadvantage of hard plastic fender.
Advantages: light weight and low price.
Disadvantages: it is easy to be damaged, and its performance will change under the influence of temperature such as thermal expansion and contraction.
Engine sinking: Like the first generation products, it is easy to break down, so it will generally not affect the engine sinking.
Third generation: Compared with the previous two generations, the crashworthiness and durability of steel fender have been obviously improved, so it has been welcomed by customers and 4S stores for a long time, but the material itself has defects, so it is gradually eliminated by the market.
Advantages: Strong impact resistance.
Disadvantages: heavy weight and obvious noise.
Engine sinking: it affects the engine sinking and is prone to personal safety hazards.
The fourth generation: alloy plastic steel guard plate
Plastic steel fender is the earliest fender with fully enclosed design. Compared with previous generations of fenders, it covers a wider area and protects the engine more. It is characterized by light weight, strong toughness and strong compression resistance.
Advantages: The alloy plastic-steel guard plate is made of brand-new innovative polymer plastic-steel materials, tailored to the original car, with strong toughness, high temperature resistance and anti-collision.
Traditional protective plates are prone to aging, deformation, vibration, rust and fracture.
Disadvantages: the material is imported polymer, which leads to high product price.
Engine sinking: A few leading brands in the domestic industry have obtained this technology patent, which does not affect engine sinking.
Fifth generation: 3D alloy guard plate
This is the first brand-new fender design concept put forward by Jia Kui brand. The 3 d fender adopts the original 3D space scanning technology to generate the real 3D image of the chassis of the original car, and then the fitting design is carried out according to the positions of each hole and each part of the chassis to ensure the perfect fitting between the fender and each part of the original car, thus reducing the ground clearance of the chassis by only 2-3CM.
Advantages: aviation aluminum alloy material, tailored according to the original chassis 3D scanning. Strong toughness, high temperature/low temperature resistance, strong collision resistance and never rust. The material itself has good heat dissipation, and the same texture is twice as light as steel plate.
Disadvantages: aviation aluminum alloy material is used, and the price of raw materials is higher, which leads to the product being slightly more expensive than the general material on the market.
Engine sinking: The patented design of sinking line of lug can ensure that 100% sinks along the sinking line when the engine is hit by a certain force.
