Engine under guard [1] is designed according to different models held engine protection device, its design is to prevent dirt parcel first engine, the engine cooling, the second is to drive to prevent impact due to uneven pavement on the engine, engine damage caused by a series of design to prolong the service life of the engine, Avoid breaking down of cars with engine damage due to external factors during travel
Classification
Hard plastic: the price is relatively cheap, the production process is simple and does not need a lot of capital and high value equipment investment, the production of this kind of protection board entry threshold is low.
Resin: The material is mainly plastic, but the ratio used in the production is different, and it does not solve the problems of collision avoidance and durability.
Steel: Once the material is listed by customers and customer groups such as the 4 s shop welcome, steel sheeting has solved the first two generation of plastic and the deficiency of resin plate, the material of the collision not only durable, but also more humanized design, machine filter for oil hole is reserved, can solve the problem of follow-up maintenance etc, and design of the ventilation holes, make the engine cooling is not affected by guard board, This is the first two generations of the protection board does not have, so the steel protection board is currently in the market for the longest time, the use of the most customer groups of a protection board, but with the continuous innovation of technology and material, steel protection board has gradually withdrawn from the market stage.
Tech: Plastic sheeting has been done to improve in many ways, is the biggest improvement point guard board layout, greater space for engine provides more protection, and increase in the thickness of the plate, but plastic material and resin material, is just the name change, its main material is still plastic, just content ratio is different, so the plastic material has fundamental flaw, The anti-collision durability is poor and can not provide anti-collision protection for the engine.
Aluminum alloy, aluminum alloy plate of steel plate is an updated products, mainly with light weight, heat dissipation, good crashworthiness and never rust etc, so the guard board industry aluminum sheeting occupy more than 70% of weight, is the mainstream of the material, and the big 4 s shop and forms a group, have also started to use it as the engine shield material used.
