Problems solved by technology
However, the high-speed air intake of the existing air intake system is insufficient, and the air intake resistance is large, resulting in insufficient fuel combustion in the engine, insufficient power, and poor fuel consumption
[0004] In addition, intake noise, as the main noise source of vehicles, bothers technicians and consumers
However, there is a trade-off between the intake resistance and the intake noise source.
Reducing the diameter of the intake and drainage pipe can increase the expansion ratio and reduce noise; however, it will increase the intake resistance, reduce the intake air volume, and affect engine performance
Increasing the diameter of the intake pipe can reduce the intake resistance and increase the intake volume; but it will reduce the expansion ratio and increase the noise

The invention provides an air intake assembly and an air intake system of an engine. The air intake assembly comprises an air filter, a first flow guiding pipe, and a second flow guiding pipe, whereinthe air filter is used for filtering air; one end of the first flow guiding pipe communicates with outside, and the other end of the first flow guiding pipe communicates with the air filter; and oneend of the second flow guiding pipe communicates with the first flow guiding pipe, and the other end of the second flow guiding pipe communicates with the air filter. The second flow guiding pipe serves as an offshoot branch of the first flow guiding pipe, and an air inlet pipeline is jointly formed by the first flow guiding pipe and the second flow guiding pipe, so that the air inflow required for high-speed running of the engine is met. One end of the second flow guiding pipe communicates with the first flow guiding pipe, so that the noise is eliminated.
Description
technical field [0001] The present application relates to the technical field of automobile manufacturing, in particular to an intake assembly and an engine intake system. Background technique [0002] Drain tube, as an important part of the air intake system, is used to guide a sufficient amount of air into the air filter and then sent into the engine. When the engine is working, the air is sucked in from the air inlet of the draft tube, then enters the air filter through the draft tube, and is sent to the engine after being filtered by the air filter. [0003] When the engine is running at a low speed, the required intake air volume is small, and the existing air intake system can meet the intake air requirements. When the engine is running at high speed, the required intake air volume is larger. However, the high-speed air intake of the existing air intake system is insufficient, and the air intake resistance is large, resulting in insufficient fuel combustion in the en...
