What does the lower guard plate of a car engine mean
Engine guard plates are engine protection devices tailor-made for various vehicle models. Their design is primarily to prevent dirt from covering the engine and secondly to prevent damage to the engine caused by impacts on uneven roads during driving.
Through a series of designs, the service life of the engine is extended to prevent the car from breaking down due to engine damage caused by external factors during travel.
The development of engine guard plates in China has mainly gone through three stages: hard plastic, resin, iron and aluminum alloy. The characteristics of different types of guard plates made of various materials are essentially different. However, the only point that must be strictly controlled is whether the engine can sink normally after the guard plate is installed. This is the most crucial issue.
The first generation: Hard plastic and resin guard plates.
The price is relatively low and the production process is simple. However, it should be noted that this material guard plate is prone to breakage, especially in winter. It is inherently vulnerable to damage and once broken, it cannot be repaired and thus cannot provide long-term protection.
Advantages: Light weight, low price;
Disadvantage: Prone to damage;
The second generation: Iron guard plate.
However, it should be noted that when choosing this type of guard plate, this material of guard plate can protect the important parts of the engine and chassis to the greatest extent, but the drawback is that it is heavy.
Advantages: Strong impact resistance;
Disadvantages: Heavy in weight, with obvious noise resonance;
The third generation: The so-called "titanium" alloy protective plate in the aluminum alloy protective plate market.
Its feature is its light weight.
Advantages: Light weight;
Disadvantages: The price of aluminum alloy is average. Due to the high price of titanium, it is basically made of aluminum material. There are no genuine titanium alloy guard plates on the market. The strength is not high, and it is difficult to reset after a collision. There is also a resonance phenomenon.
The fourth generation: Plastic-steel "alloy" guard plate.
The main chemical component of plastic steel is modified high-molecular polymer alloy plastic steel, also known as modified copolymer PP. This material has excellent performance, is easy to process and has a wide range of applications. Due to its physical properties such as rigidity, elasticity, corrosion resistance and anti-aging performance, it is usually used as an excellent substitute for non-ferrous metals such as copper, zinc and aluminum. It will not hinder the sinking function in the event of a vehicle collision.
Keep the engine compartment clean to prevent water and dust from the road surface from entering it.
Prevent sand, stones and hard objects lifted by the tires during car operation from hitting the engine, as this phenomenon occurs.
It won't have an impact on the engine in the short term, but over time, it will still have an effect on the engine.
It can also prevent the engine from being scratched by uneven roads and hard objects.
Disadvantage: Hard engine guard plates may impede the protective sinking of the engine during a collision, thereby weakening the protective effect of engine sinking.
Hard plastic resin
The price is relatively low, the production process is simple, and it does not require a large amount of capital or high-value equipment investment. The entry threshold for producing such guard plates is relatively low.
Steel
However, it should be noted that when choosing this type of protective plate, the matching of its design style with the vehicle and the quality of the accompanying accessories must be selected. Products from regular manufacturers must be chosen.
Aluminum alloy
It should be noted that many beauty salons strongly promote this product, attracted by the high profit behind its high price, but its hardness is far inferior to that of steel protective plates. The repair of damage is rather difficult, and the alloy material is extremely complex, making it hard to determine its characteristics.
Plastic steel
The main chemical component is modified high-molecular polymer alloy plastic steel, also known as modified copolymer PP. This material has excellent performance, is easy to process and has a wide range of applications.

It will not impede the sinking function when a vehicle collision occurs.
