Abstract

The invention relates to the technical field of environmental monitoring instruments, and particularly provides an exhaust gas monitoring instrument which comprise a host computer, a sampling system, a motor vehicle uphill-downhill determination device, an engine speed measurement system, an oil temperature sensor, an exhaust gas temperature sensor, a control terminal, an alarm device and a wireless data transmission system, wherein the host computer comprises an exhaust gas measuring system and an interface control part; the host computer is mounted in a relatively clean position in the motor vehicle; the exhaust gas of the motor vehicle enters the exhaust gas measuring system through a sampling system; the motor vehicle uphill-downhill determination device, the engine speed measurement system, the oil temperature sensor, the exhaust gas measuring system, the alarm device, the wireless data transmission system and the control terminal are respectively connected with the host computer; the wireless data transmission system is used for directly transmitting test data to an environmental monitoring central station. The exhaust gas monitoring instrument provided by the invention can monitor the smoke condition of a diesel engine or the exhaust gas emission state of an automobile engine in real time, and can be widely used for monitoring the exhaust gas emission of the motor vehicle in real time.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring instruments, in particular to an exhaust gas monitoring instrument. Background technique [0002] As one of the most important means of transportation in modern society, automobiles have brought great convenience to people's life and work, but the exhaust emitted by automobiles has also become another source of air pollution besides soot-type air pollution. Correspondingly, the total amount of vehicle pollutant emissions is rising rapidly. Major cities across the country are seriously polluted by vehicle exhaust. It is of great significance to protect the human living environment by detecting the automobile exhaust pollution. [0003] With the increase of motor vehicles and the improvement of people's environmental awareness, my country has formulated a series of national standards such as GB18285-2005, GB3847-2005, GB3842-83, GB7258-87, and GB1495-79 on exhaust emissions, smoke...
