Automobile engine air-taking system

Abstract

The invention discloses an automobile engine air-taking system. The air-taking system still arranges an air intake at the front end of an automobile body so as to preserve the effect of the existing automobile body front air-taking proposal that the generated air flow is large and the cleanness is high; compared with the existing mode of air-taking inside an engine cabinet, the system avoids the decrease of engine power caused by the low air flow density; compared with the existing mode of air-taking at the outer side of the automobile body, the system avoids the decrease of engine power caused by the poor cleanness of air flow and prevents the service-life consumption of the engine. In addition, the existing automobile body system is provided with the left and right automobile body longitudinal beams and the inner parts of the automobile body longitudinal beams are provided with sealed cavities, the invention arranges the automobile body longitudinal beams in the automobile body system into the air-taking system to be served as pipelines of the air-taking system, therefore other structures do not need to be arranged as the pipelines of the air-taking system, can simplify the pipeline structure of the air-taking system, save body space and reduce cost for the automobile body layout arranging in the middle or the back in the engine.

Description

technical field [0001] The invention relates to parts of automobiles, in particular to an air intake system of an automobile engine. Background technique [0002] With the development of the automobile industry, how to increase engine power and reduce engine life loss has increasingly become the focus of the world's major vehicle manufacturers. [0003] Improving engine power and reducing engine life loss mainly depend on the following three aspects: [0004] First, the manufacturing precision and matching precision of the internal parts of the engine. [0005] Second, the material and structure of the engine intake manifold. [0006] Third, the air intake method of the engine. [0007] Among them, the air intake methods mentioned in the prior art for the above third point are usually divided into: air intake from the front of the vehicle body, air intake from the inside of the engine compartment, and air intake from the outside of the vehicle body. [0008] In the air i...

Problems solved by technology

[0013] It can be seen that for the body layout with the engine in the middle and the rear, if the air intake system adopts the existing air intake method at the front of the car body, although a large airflow and a high degree of cleanliness can be obtained, the pipeline structure is relatively complicated, Occupies a large body space and high cost; if the air intake system using the existing air intake method in the engine compartment is used, the engine power will be reduced due to the low intake air flow density; and if the existing air intake system outside the car body is used The air intake system of the air intake method will reduce engine power and shorten engine life due to poor cleanliness
