Embodiment approach

[0049] The optimal implementation mode: if Figure 1-10 As shown, a sound-absorbing car intake pipe system includes an air filter connecting section pipe 1 whose integrally curved end is used to connect with the air filter outlet, and an integrally curved end is used to connect with the engine throttle. Connected engine connection pipe 2, which also includes the intermediate pipe 4 fixedly connected to the air filter connection pipe and the engine connection pipe through the clamp 3 (the clamp adopts a spring turbine worm clamp, which has a clamping force Large, uniform force in the circumferential direction, with pre-tightening effect, etc., suitable for the connection between the hard material pipe and the flexible material pipe here), the material hardness of the middle pipe 4 is greater than that of the air filter connecting section pipe 1 and the engine connecting section The pipe 2 has a material hardness, and the middle section pipe 4 is provided with a pipe fixing stru...

Abstract

The invention discloses a silenced car air intake pipe system. The system is characterized in that an air intake silencer based on the Helmholtz silencing principle is arranged in the air intake pipe system and comprises a core pipe, wherein a channel part for ventilation is formed in a cavity of the core pipe, a plurality of silencing holes are uniformly formed in the middle of the core tube in the circumferential direction, a silencing casing is arranged on the periphery of the middle of the core tube in a sleeving manner, two ends of the silencing casing and the core tube are sealed, and a chamber part for producing a resonant silencing effect is formed between the silencing casing and the core tube. The system has the advantages of being simple in structure, convenient to connect and assemble, capable of reducing noise and vibration and the like.

Description

technical field [0001] The invention relates to the field of car engine air intake systems, in particular to a noise-absorbing car intake pipe system. Background technique [0002] The assembly of parts that introduces air or mixed gas into the engine cylinder in a car is called the engine intake system. In the engine air intake system, the air filter is the main component of the air intake part, which is used to filter the air entering the engine. The air filter is generally arranged above the engine, and the air outlet of the air filter is connected to the engine throttle through the intake pipe. [0003] The existing car air intake pipeline system generally adopts the structural form of an integral hose or a two-section butt joint hose. For example, CN201520081736.6 discloses a kind of automobile engine intake pipe, which includes intake pipe 1 and intake pipe 2, the intake pipe 1 and intake pipe 2 are connected by a curved pipe, the intake pipe 1, the intake pipe 2 and...
