Abstract
The invention discloses a device for simulating an evolution process of an internal combustion engine exhaust particle flow for reducing automotive emissions, and the device comprises an exhaust source; an exhaust channel, comprising a plurality of sections of cylindrical tubes with specified length that are fixedly connected; a soluble organic compound generator, used to produce soluble organic compounds; a carbon particle generator, used to produce carbon particles. The device for simulating the evolution process of an internal combustion engine exhaust particle flow for reducing automotive emissions has the advantages of simple structure and low cost; controls the mixing concentration of soot particles and soluble organic compounds through various adjustment methods to obtain a suitable mixed aerosol, so as to better simulate the exhaust particle flow of an internal combustion engine.
