It promoted the revolution in the automotive industry, also contributed to the development of the fuel, purification technology and monitoring equipment and other related industries. The mon gas analysis method, the advantages of infrared optical absorption apparatus is high precision and sensitivity, fast response, wide measurement range, good selectivity and stability and reliability, rapid and continuous detection. So valued by many countries , widely used. In this paper, as far as possible to eliminate the effect of environmental interference, improve the accuracy of the exhaust gas detection. Can technology in the actual situation according to the results of evaluation of engine, especially the technical condition of the fuel supply system and ignition system. In this paper, through the design of automobile exhaust detection system, work carried out the following: One is the analog signal acquisition, processing and conversion, the paper in the process of data acquisition due to outside interference, resulting in the test results is not accurate enough, in view of the outside interference analysis the influence of the environment, the environment including temperature, pressure, humidity。 本論文盡可能消除環(huán)境干擾影響，提高尾氣檢測的精確性。哈爾濱理工大學(xué)學(xué)士學(xué)位論文 I 汽車尾氣質(zhì)量檢測系統(tǒng)設(shè)計(jì) 摘 要 對汽車排放污染物的治理，是世界性的環(huán)保課題。因此受到各國重視，獲得廣泛應(yīng)用。測試得到的瞬態(tài)油耗可以結(jié)合四種排放污染物的體積濃度計(jì)算得到質(zhì)量排放率；五是 各項(xiàng)參數(shù)數(shù)值的計(jì)算，并根據(jù)檢測結(jié)果受環(huán)境影響的大小，采用不同的補(bǔ)償方法，最終得到正確的結(jié)果。 four is used to test vehicle measurement meter fuel consumption, as with the airfuel calculation parison standard oil consumption ratio method an
