[0013] However, although Korean Laid-Open Patent Publication No. 10-2016-0024435 has changed the joint structure of the intake pipe for noise reduction, it still has and uses a resonant cavity, which makes the engine room space insufficient
[0014] Furthermore, Korean Laid-Open Patent Publication No. 10-2009-0109817 can secure the space of the engine room because it does not have a resonant cavity, but the structure of the air duct is complicated, and it cannot run smoothly when the air flowing in from the outside contains foreign matter such as fine sand. Its manufacturing process is complicated and the production cost is high

Abstract
The present invention relates to a vehicle compact intake duct and a manufacturing method thereof. The vehicle compact intake duct includes a hollow body with one side connected to the engine air inlet and the other side communicated with the outside, an opening formed in an outer wall of the body, and a sound absorbing plate provided in the opening to reduce the vibration and noise on the intake duct without the resonant cavity. The structure of the intake duct is simplified to improve the production efficiency and secure the engine room, and the design practicability is improved due to the space guarantee.
Description
technical field [0001] The invention relates to a compact air intake pipe for vehicles and a manufacturing method thereof. Background technique [0002] In general, an internal combustion engine mixes fuel with oxygen, and the mixed fuel is supplied to the inside of the cylinder of the engine and ignited. At this time, the explosive force generated by the ignition converts the generated linear motion into rotary motion to generate power. [0003] The above-mentioned internal combustion engine must be supplied with oxygen. The engine is an internal combustion engine installed in a vehicle. The method of supplying oxygen to the engine is as follows. Considering the driving direction of the vehicle, the suction port is placed in the engine room in front of the vehicle so that it faces the driving direction side of the vehicle. [0004] As mentioned earlier, the air intake arrangement for supplying oxygen to the internal combustion engine can exert the effect of increasing the a...
