Description

Technical Field

[0001] This utility model relates to the technical field of engines, and in particular to a plastic air intake pipe. Background Technology

[0002] An engine is a machine that converts some form of energy into mechanical energy. It is widely used in automobiles, airplanes, ships, power generation equipment, and many other fields, and is a core power unit in modern industry and transportation.

[0003] Currently, most naturally aspirated engines, when equipped with a built-in air filter, typically place the air filter in front of the radiator. The intake pipe between the air filter and the engine intake manifold is usually made and installed using steel tubing, and this intake pipe needs to extend over the top of the radiator, resulting in an excessively high structural height, which affects the shape of the tractor hood's windward side. Therefore, a lower-height intake pipe is needed. This plastic intake pipe is convenient to produce, has high manufacturing efficiency, and reduces costs while lowering the height.
