Engine guard.
The engine protection board is an engine protection device designed according to a variety of different models, which is designed first to prevent soil from covering the engine, and secondly to prevent damage to the engine caused by the impact of the uneven road surface on the engine during driving.
Through a series of designs to extend the service life of the engine, to avoid the process of travel due to external factors caused by engine damage to the car breakdown.
The development of engine protection board in China mainly has three stages: hard plastic, resin, iron and aluminum alloy.
Different material types of protection board, its characteristics are essentially different. But the only point must be strictly controlled: whether the engine can sink normally after installing the guard plate is the most critical problem.
The first generation: hard plastic, resin protection board. The price is relatively cheap, the production process is simple, but it should be noted that this material is easy to break the winter is even more so, itself is vulnerable to damage after the broken can not be repaired can not play a long-term protective role. Advantages: light weight, low price; Cons: Easy to damage.
The second generation: iron guard plate. However, it should be noted that when choosing this kind of protection board, the protection board of this material can protect the important parts of the engine and chassis to the greatest extent, but the disadvantage is that the weight is heavy. Advantages: strong impact resistance; Disadvantages: Heavy weight, obvious noise resonance.
The third generation: the so-called "titanium" alloy protection plate on the market. It is characterized by its light weight. Advantages: Light weight; Disadvantages: The price of aluminum alloy is general, because the price of titanium is too high, so the basic are made of aluminum material, there is no real titanium alloy plate on the market, the strength is not high collision is not easy to reset, there is resonance phenomenon. Fourth generation: Plastic steel "alloy" protection plate. The main chemical composition of plastic steel is modified polymer alloy plastic steel, also known as modified copolymerization PP. The material has excellent performance, easy processing and wide use. Due to its physical properties such as rigidity, elasticity, corrosion resistance and excellent anti-aging performance, it is usually used as a good substitute for non-ferrous metals such as copper, zinc and aluminum, and will not hinder the sinking function when the vehicle crashes.
Keep the engine compartment clean to prevent road water and dust from entering the engine compartment. Prevent the sand and gravel that roll up after the tire is rolled by the car during the driving process from hitting the engine, because the sand and gravel and hard objects hit the engine. It will not affect the engine for a short time, but it will affect the engine for a long time. It can also prevent uneven road surface and hard objects from scratching the engine. Disadvantages: The hard engine shield may hinder the engine protective sinking in the process of collision, and weaken the protective effect of the engine sinking.
The price of hard plastic resin is relatively cheap, the production process is simple and does not require a lot of capital and the investment of high value equipment, and the entry barrier to the production of such protection board is low. However, it should be noted that when choosing this protection board, it is the match between the design style and the car and the quality of the supporting accessories, and it must use the products of regular manufacturers. Aluminum alloy needs to be noted that many beauty shops are pushing this product, looking at the high profit behind its high price, but its hardness is far less than the steel protective plate. The damage is difficult to repair, and the alloy material is extremely complex and it is difficult to determine its characteristics. The main chemical composition of plastic steel is modified polymer alloy plastic steel, also known as modified copolymerization PP. The material has excellent performance, easy processing and wide use. 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. Does not hinder the sinking function in the event of a vehicle crash.
Alloy plastic steel material: improved polymer polymer polymer alloy plastic steel. It has strong resilience and impact resistance. It is usually used as a good substitute for non-ferrous metals such as copper, zinc and aluminum. Seal: Compared with the traditional metal alloy guard plate, the plastic steel guard plate is designed to be more sealed and can withstand 99 percent of the mud and water erosion resulting in engine aging. The unique design of the inlet and outlet avoids the turbulence of the engine compartment to reduce wind resistance, reduce noise and reduce fuel consumption.
Car type such protection board is generally steel protection board, because the car chassis is generally only about 20 cm from the ground, the first thing to consider is to prevent the drag and impact of the engine. Of course, there are also many "premium cars" with aluminum alloy protection plates. Small car type small car, van manufacturers in the factory when the installation is hard plastic, resin protection board, this protection board generally can only have a certain protective effect on the road soil. Off-road vehicles are generally used for non-normal road driving, so the engine shield is an indispensable main component, each manufacturer has been installed before the factory has a very strong steel shield.
The price of the protection board on the engine protection board market is not uniform, ranging from several hundred yuan to thousands of yuan, but basically all the materials used in the construction of the protection board are basically similar, but the manufacturer is not the same. It is best to go to the regular car service shop and look for brand products. If you decide to install the shield, please be sure to look at the equipment in the construction place, the construction of the shield is quite laborious. First of all, carefully remove the chassis oil, the use of special detergent to thoroughly remove the asphalt, oil, etc., drying, any negligence in these treatments will affect the robustness of the board. Then, the parts that need to dissipate heat, such as the transmission shaft and the exhaust pipe, are sealed with tape or waste newspaper. To avoid accidental damage, affect their normal operation, and to remove these tapes or newspapers after the completion of construction, to avoid danger. In a word, the heart of the engine car needs care, but also needs protection, and choosing a good protection board can make your love car ride more comfortable.
