Technical Field

[0001] The utility model relates to the technical field of automobile engine intake pipes, in particular to a high-buffered and lightweight turbocharged intake pipe. Background Art

[0002] At present, fuel vehicles have always occupied a dominant position in the automobile market. Fuel vehicles refer to vehicles that use gasoline, diesel and other fuels as power sources. Their advantages are long driving range, convenient refueling, low fuel cost, etc. Fuel vehicles are driven by engine combustion, and the intake pipe is required to deliver clean, dry, sufficient and stable air to the engine to meet the needs of the engine, so as to prevent impurities and large dust particles in the air from entering the engine combustion chamber and causing abnormal wear of the engine.

[0003] With the improvement of environmental protection requirements, the requirements for engines are further improved, and requirements for higher efficiency, lower cost, lower emissions, lighter weight, and more environmentally friendly materials are put forward. The use of turbocharged engines is one of the preferred solutions to meet environmental emissions. The boost pipeline is an important link to ensure that air enters the engine at high pressure and high flow rate for combustion, which can improve fuel economy. The traditional boost pipeline is composed of plastic pipes, rubber pipes, sensors and other components. Rubber pipes are non-recyclable materials with high density, relatively large weight, and poor plasticity. They cannot better meet the assembly space requirements. As customers have higher and higher requirements for vehicle performance, comfort and economy, higher requirements are put forward for the product's cushioning, recyclability, lightweight and low cost.
