Since automobile exhaust gas usually contains various harmful gases such as carbon monoxide, hydrocarbons, sulfur oxides, and nitrogen oxides. Each of these gases has a specific characteristic absorption band and characteristic frequency that is strongly absorbed when the infrared spectrum falls near the characteristic frequency band. Therefore, the infrared spectrum of the corresponding characteristic frequency can be used to detect the components of the harmful gas in the exhaust gas, and the amount of the absorbed external spectrum can detect the type and content of the corresponding gas.
