Abstract

The invention discloses an in-vehicle air quality pre-evaluation method. The method comprises the steps of giving a plurality of in-vehicle parts; testing each part in a vehicle to obtain an initial diffusible concentration, a diffusion coefficient and a separation coefficient of pollutants; according to the initial diffusible concentration, the diffusion coefficient and the separation coefficientof each part in the vehicle, a given mass diffusion equation in the part, an initial condition of the mass diffusion equation and a boundary condition, obtaining a pollutant emission rate of a material per unit area of each part in the vehicle; and obtaining concentration change information of air mass in the vehicle according to the pollutant emission rate of the material per unit area of each part in the vehicle, a preset mass conservation equation and pollutant information inside and outside the vehicle. The method has advantages that a pollution emission process of the parts in the vehicle is described based on a material pollution emission model, based on that, the air quality of the whole vehicle is simulated and evaluated, and an air quality condition in the vehicle can be evaluated in a whole vehicle design stage.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for pre-evaluating air quality in a vehicle. Background technique [0002] As cars enter thousands of households, the problem of air pollution in cars has become the focus of car quality. In-vehicle air quality control is a multi-factor and multi-level complex project. The core of the control is how to select appropriate in-vehicle components and materials, and at the same time put forward clear requirements and supervision management on assembly process and production control. At present, the automotive industry lacks a quantitative evaluation method for the selection of parts. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] For this reason, the object of the present invention is to propose a method for pre-assessing the air quality in the vehicle, which can carry out quantitati...
