Air inflow ducting device for vehicle engine

Abstract

The invention discloses an air inflow ducting device for a vehicle engine. The device comprises at least one round sheet-shaped main body with the outer edge provided with a circular ring; the circular ring can be fixed at the inner edge of an air inflow tube, the inner periphery of the circular ring is provided with a plurality of turbulent flow holes, and the plurality of turbulent flow holes are arranged at least in two columns from the inner periphery to the central point of the circular ring so as to form a grille shape; and each turbulent flow hole is internally provided with at least one turbulent flow plate which has a tilting angle relative to the axial direction of the air inflow tube. When the airflow from the intake tube of the vehicle passes the main body, the airflow can be dispersed by the function of the plurality of turbulent flow holes and the turbulent flow plate in each turbulent flow hole, thereby the air inflow tube can intake air uniformly.

Description

technical field [0001] The invention relates to an air guide device, in particular to an air guide device which can be fixed on the inner edge of an air intake pipe. When the airflow from the intake pipe of a vehicle passes through the air guide device, the airflow can be dispersed without concentrating. Background technique [0002] In order to enable the engine to have a better air intake effect at high speeds, there are a variety of spoilers installed on the front end of the intake pipe on the market. The purpose is to make the air in the front end of the engine air intake pipe flow , can produce a swirl flow vortex, this kind of vortex can make the air pass through at a high speed in the form of a vortex when a large amount of air enters the intake pipe. [0003] Such as figure 1 As shown, it is a spoiler structure that has been circulated on the market. The spoiler is installed in the pipeline at the front end of the engine air intake. A central empty pipe 91 with a s...

Problems solved by technology

[0005] Except above-mentioned two kinds of existing spoilers, other similar structures such as: U.S.patent 5,113,838, 6,158,412, 6,796,296 etc., no matter which kind of prior art, its design key point is all to allow airflow to take in the mode of vortex airflow, this This air intake method may be able to achieve the function of accelerating the intake air, but at the same time it also has the disadvantage of uneven air intake

[0006] Especially in the above design, the gap between two adjacent blades is from the center point of the spoiler to the outside, presenting a state of gradual opening, that is, the gap between the blades is closer to the center point. The position gap is smaller; therefore, when the air is inhaled, the wind resistance close to the center point of the spoiler will be much greater than the wind resistance away from the center point, making the air intake of the overall spoiler uneven

In the case of uneven air intake, if the user adds air catalyst or other combustion-supporting substances at the intake end of the engine, for example: nitrous oxide (N 2 O), will make said these air catalysts or combustors unable to spread evenly

In addition, since each blade of the existing spoiler has a different curvature extending from the center point outward, it is more difficult to manufacture
