A vehicle air intake structure, a vehicle air intake system and corresponding vehicle

Abstract

The invention discloses an air feeding structure for an automobile. The air feeding structure for the automobile is arranged between an air feeding grid of the automobile and a corrugated tube. The air feeding structure is that an upper part and a lower part are combined to form a cavity; a main air inlet and a tubular body are formed in the cavity; a downwards-inclined flow guide plate is arranged at the main air inlet; a strip-shaped opening is formed in the wall of the tubular body of the flow guide plate; a main air inlet is formed in the lower side edge of the flow guide plate and communicated with the inner part of the tubular body through the strip-shaped opening; a space is formed between the lower side of the flow guide plate and the lower part of the tubular body and is divided into a main cavity and a secondary cavity through a separating plate, wherein the main cavity is communicated with the secondary cavity; a plurality of secondary air inlets are formed in the wall of the tubular body, close to the secondary cavity and used for communicating the secondary cavity with the tubular body. The invention further discloses an air feeding system for the automobile and the corresponding automobile. With the adoption of the air feeding structure, clean air at proper temperature can be provided to an engine.

Description

technical field [0001] The invention belongs to an air intake structure of an automobile engine, in particular to an air intake structure for a vehicle, an air intake system for a vehicle and a corresponding automobile. Background technique [0002] The air filter mainly filters the air sucked into the engine to protect the cylinder, piston and piston ring of the engine from the wear of pollutants, so that the engine can obtain the best air-fuel ratio mixture under different working conditions to improve the power of the engine , economy, and reduce exhaust pollution; while the existing air intake system in rainy days and car washes, water droplets easily flow into the air filter body from the air intake, causing the filter element to absorb water, thereby increasing the air intake resistance and shortening the life of the filter element , affecting engine performance.

AI Technical Summary

Problems solved by technology

[0002] The air filter mainly filters the air sucked into the engine to protect the cylinder, piston and piston ring of the engine from the wear of pollutants, so that the engine can obtain the best air-fuel ratio mixture under different working conditions to improve the power of the engine , economy, and reduce exhaust pollution; while the existing air intake system in rainy days and car washes, water droplets easily flow into the air filter body from the air intake, causing the filter element to absorb water, thereby increasing the air intake resistance and shortening the life of the filter element , affecting the performance of the engine

Especially when driving on snowy roads, because the snow will be lifted up and intruded into the air filter with the air flow, accumulating for a long time will cause the filter element of the air filter to be clogged, thus affecting the air intake performance

At the same time, a higher intake air temperature will lead to a decrease in engine power and an increase in fuel consumption

[0003] Therefore, the existing air intake system pipelines have poor anti-rain and snow performance. After the intrusion of rain and snow, it is impossible to separate the rain, snow and larger particles from the air; It is necessary to change the layout position of the air intake system pipeline. For example, the air intake cannot be directly arranged at the air intake grille of the vehicle; in addition, because the existing air intake is arranged inside the engine room, it will be affected by the temperature of the engine, so that Intake air temperature is high, which affects engine performance
