Abstract

The invention discloses a trolley type tail gas carbon dioxide discharge amount detector for an automobile and a detection method thereof. The detector comprises an exhaust pipe interface, a detection pipe, an exhaust flow device, a temperature sensor, a carbon dioxide sensor, a detection instrument, a storage battery and a trolley. Under the condition that the automobile is stopped and an engine is started up, the detector is pressed against an exhaust pipe outlet formed behind the bottom of the automobile, and the discharge amount of carbon dioxide (CO2) in automobile tail gas is detected through the exhaust flow device and a gas-sensitive element in the detector; the detector has the characteristics of high accuracy, high resolution, large measuring range, small size, high maneuverability, easiness and convenience for operating and capability of displaying data in real time, and new apparatus equipment is provided for acquisition and analysis of data of automobile tail gas influencing the environment.

Description

technical field [0001] The invention relates to an instrument for detecting carbon dioxide emission in automobile tail gas, in particular to a cart-type automobile tail gas carbon dioxide emission detector and a detection method thereof. Background technique [0002] At present, to detect the carbon dioxide emissions in vehicle exhaust, it is necessary to go to a special vehicle testing site for testing. However, the portable carbon dioxide detectors on the market can only detect the content of carbon dioxide in the air, but cannot detect the content of carbon dioxide in the exhaust of automobile exhaust pipes. Therefore, the existing instruments and equipment are not convenient for collecting and analyzing the impact of automobile exhaust on the environment. data. Contents of the invention [0003] Aiming at the deficiency of existing equipment for detecting carbon dioxide emissions in automobile exhaust, the present invention proposes a cart-type automobile exhaust carb...
