Abstract

The invention relates to a Fourier infrared automobile exhaust evaluation system. The Fourier infrared automobile exhaust evaluation system is characterized by comprising a gas control part, a gas reaction part, an exhaust detection part and a data processing and outputting part, wherein the gas control part comprises an evaluation gas mixing cabinet, a thermostatic water bath, a first mixing tank and a second mixing tank, a gas inlet line of the evaluation gas mixing cabinet is connected with a simulated exhaust source, a gas outlet of the evaluation gas mixing cabinet is connected to the first mixing tank, an outlet of the first mixing tank is connected to the second mixing tank, the thermostatic water bath is connected to the second mixing tank through a steam line, and an outlet of the second mixing tank is connected with the gas reaction part; the gas reaction part comprises a tubular furnace, a reaction tube is arranged in the tubular furnace, and a catalyst sample is placed in the reaction tube; the exhaust detection part adopts an infrared analysis instrument, and a gas pool of the infrared analysis instrument is connected with a gas outlet end of the reaction tube. With the adoption of the Fourier infrared automobile exhaust evaluation system, the concentration of each gas component can be accurately detected in the combustion process of fuel.

Description

technical field [0001] The invention relates to a Fourier transform infrared automobile tail gas evaluation system, in particular to a CNG tail gas catalyst sample performance evaluation system in a laboratory, which is used to test catalyst activity tests including light-off temperature characteristic test and air-fuel ratio characteristic test. Background technique [0002] Compressed natural gas (CNG) is a universal fuel suitable for light, medium and heavy duty vehicles. Research results in recent years have shown that compared with diesel vehicles, polycyclic aromatic hydrocarbons (AHs) in the exhaust of CNG vehicles are 50 times lower than diesel vehicles, formaldehyde is 20 times lower, particulate matter (PM) is 30 times lower, and total toxicity is 20-30 times lower. Based on the research results on exhaust emissions, European and American countries have launched a natural gas vehicle program in cities, replacing diesel vehicles with CNG vehicles (including buses an...
