[0002] In order to improve the performance of vehicle engines, turbocharging technology is increasingly widely used in existing technologies to provide more air to the engine to stimulate higher engine power and torque. Lightweighting of vehicles is a hot topic in the current automotive industry and an inevitable trend for the future development of major automobile manufacturers. Currently, one of the main ways to lightweight vehicles is to use new materials instead of metal materials, such as engineering plastics, which have good high temperature resistance, corrosion resistance and other characteristics. The use of engineering plastics can reduce the weight of the vehicle body.

[0003] Most of the current intake pipes are one-piece structures, and when the intake pipe is damaged, the entire intake pipe needs to be replaced. However, in actual use, when the intake pipe is damaged, it is mostly one end of the intake pipe that is damaged, and the rest of the pipe can still work normally. The overall replacement solution is costly, the customer experience is poor, it is not conducive to maintenance, and it is easy to cause certain waste. Utility Model Content

[0015] Furthermore, a placement groove is provided on the inner top wall of the slide groove, a placement block is slidably arranged in the placement groove, and the placement block and the slide block are fixed to each other.

[0016] By adopting the above technical solution, after the staff connects the positioning plate with the corresponding slot on the engine, the staff only needs to push the placement block to make the slider move with the placement block, and then extend the slider outside the annular plate, so that the annular plate and the slot cooperate with each other and limit the positioning plate, which is beneficial to improve the stability of the boost pipe.

[0017] Furthermore, the boost pipe is made of PA6+15GF.

[0018] By adopting the above technical solution, the polyamide glass fiber reinforced material can add glass fiber content in the range of 5-60% according to the characteristics of the product. This type of material has good strength, heat resistance, excellent impact resistance, good dimensional stability and low warpage, etc. The booster pipe made of PA6+15GF has good structural strength, light weight and low cost.
