Vehicle gas inlet device

Abstract

The invention discloses a vehicle gas inlet device. The vehicle gas inlet device comprises a gas inlet grid, a gas inlet path main body, a gas outlet tube, an L-shaped guide plate and an inclined guide plate which are sequentially connected. According to the vehicle gas inlet device provided by the invention, the L-shaped guide plate and the inclined guide plate are arranged on the inner part of the gas inlet path main body for guiding liquid which enters the inner part of the gas inlet path main body, so that fluid finally flows to a water draining hole in a blocking part and is drained to the outside while gas is not affected, and therefore, rainwater is prevented from entering a gas outlet tube at the downstream of the gas inlet path to cause adverse effects on an air filter and even abooster at the downstream, an engine and the like.

Description

technical field [0001] The invention relates to the field of air intake, in particular to a vehicle air intake device. Background technique [0002] The primary function of the air intake system is to provide the engine with clean, dry air at the proper temperature for combustion to minimize engine wear and maintain optimum engine performance. Due to the harsh working environment of light trucks, the air intake method of high-level air intake is generally used in light trucks at present, and the air intake duct has become an important part of the air intake system. As the first pass of the light truck air intake system, the air intake is very important to the function of the intake system to provide dry air, so the first pass - the waterproof function of the air intake is very important. [0003] The existing shape structure of the intake port is composed of an intake grille, a main body of the intake port and a resonant cavity. The outer grille of the air intake is fixed ...

AI Technical Summary

Problems solved by technology

[0005] Due to the space limitation of light trucks, the design of brushed cloth and inner grille reduces the air intake area of ​​the already small air intake, resulting in increased air intake resistance, which in turn increases fuel consumption and reduces power economy; moreover, brushed cloth In heavy rain or rainstorm weather, the water intake is already very large, so it is difficult to absorb water and let the water flow down the inner wall of the air intake. Instead, most of the water still enters the downstream of the air intake along with the airflow. The outlet pipe of the air outlet will have adverse effects on the downstream air filter, even the supercharger, engine, etc.
