The engine guard is an engine protection device designed according to various models. Its design is first to prevent the mud from wrapping the engine, and secondly to prevent the engine from being damaged due to the impact of the uneven road on the engine during driving.
Through a series of designs, the service life of the engine can be extended, and the car with the engine damaged due to external factors can be prevented from breaking down during travel.
The development of engine guard plates in China mainly has three stages: hard plastic, resin, iron and aluminum alloy. The characteristics of different types of guards are essentially different. But the only point must be strictly checked: whether the engine can sink normally after installing the fender is the most critical issue.
The first generation: hard plastic, resin guard plate.
The price is relatively cheap and the production process is simple, but it should be noted that this kind of guard plate is easy to break in winter, especially in winter.
Advantages: light weight, low price;
Disadvantages: easy to damage;
Second generation: iron guard plate.
However, it should be noted that when choosing this kind of guard plate, the guard plate of this material can protect the important parts of the engine and chassis to the greatest extent, but the disadvantage is that it is heavy.
Advantages: strong impact resistance;
Disadvantages: heavy weight, obvious noise resonance;
The third generation: the so-called "titanium" alloy protective plate in the aluminum alloy protective plate market.
Its characteristic is light weight.
Advantages: light weight;
Disadvantages: The price of aluminum alloy is average. Because the price of titanium is too high, it is basically made of aluminum material. There is no real titanium alloy guard plate on the market, and the strength is not high. It is not easy to reset after collision, and there is resonance.
The fourth generation: plastic steel "alloy" guard plate.
The main chemical composition of plastic steel is modified polymer alloy plastic steel, also known as modified copolymer PP. The material has excellent performance, convenient processing and wide range of uses. Due to its physical properties such as rigidity, elasticity, corrosion resistance and excellent anti-aging properties, it is usually used as a good substitute for non-ferrous metals such as copper, zinc and aluminum. Will hinder the sink function.effect
Keep the engine compartment clean to prevent water and dust from the road surface from entering the engine compartment.
Prevent the hard sand and gravel objects rolled up by the tires from hitting the engine during the driving process, because the sand and gravel hard objects hit the engine.
It will not affect the engine in a short time, but it will still have an impact on the engine after a long time.
It can also prevent uneven road surfaces and hard objects from scratching the engine.
Disadvantages: Hard engine guards may prevent the engine from sinking protectively during a collision, weakening the protective effect of engine sinking.Classification
hard plastic resin
The price is relatively cheap, the production process is simple and does not require a lot of capital and high-value equipment investment, and the entry threshold for the production of such protective panels is low.steel
However, it should be noted that when choosing this kind of protective plate, it is the matching of its design style with the car and the quality of the supporting accessories, and the products of regular manufacturers must be selected.Aluminum alloy
It should be noted that many beauty stores are pushing this product, and they are looking at the high profit behind its high price, but its hardness is far less than that of a steel protective plate. It is difficult to repair the damage, and the alloy material is extremely complex and it is difficult to determine its characteristics.Plastic steel
The main chemical composition is modified high molecular polymer alloy plastic steel, also called modified copolymer PP. The material has excellent properties, is easy to process, and has a wide range of uses. Because of its physical properties such as rigidity, elasticity, corrosion resistance, and excellent anti-aging properties, it is usually used as a good substitute for non-ferrous metals such as copper, zinc, and aluminum. The sinking function will not be hindered in the event of a vehicle collision.
