Abstract

The invention relates to a vehicle-mounted emission detection device which comprises a control system, a shell, a sampling probe arranged outside the shell and connected to the shell, a power supply module, a communication module, a positioning module, a sampling port, an air pump, a filter, a condenser, a water blocking device, a detection module, an exhaust port and a flow meter. The power supply module, the communication module, and the positioning module are arranged in the shell; and the sampling port, the air pump, the filter, the condenser, the water blocking device, the detection module, the exhaust port and the flow meter are sequentially arranged in the shell according to an airflow path. The device is high in measurement precision and reasonable and effective in energy distribution.

Description

technical field [0001] The invention relates to the field of emission detection, in particular to a vehicle-mounted emission detection device. Background technique [0002] The emission detection device is a device used to detect the content of each component in the vehicle exhaust gas. The traditional emission detection device is applied in the laboratory, and the exhaust gas of the engine is detected by simulating the driving of the automobile engine in the laboratory. [0003] After experiencing the fraudulent exhaust emission of Volkswagen in Germany, the emission detection device began to be improved to be able to follow the vehicle to detect the exhaust emission of the vehicle in a real environment. Since the vehicle-mounted emission detection device follows the vehicle, there are many interference factors in the external environment to the detection device: 1. Different road conditions, different engine powers, and different engine emissions. 2. In different environm...
