Description

technical field [0001] The invention relates to a vehicle exhaust gas detection and analysis instrument, in particular to a portable vehicle exhaust gas analyzer based on the National IV standard and an analysis method thereof. Background technique [0002] With the development of our country's economy, the number of automobiles has increased, and automobile transportation plays an important role in the national economy. However, the carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NO) contained in the tail gas emitted by automobiles X ), sulfur oxides (SO X ) and other harmful gases, causing serious environmental pollution and endangering people's health. To this end, the country has issued "Light Vehicle Pollutant Emission Limits and Measurement Methods (China III, IV Stages)" (GB18352.3-2005), which is equivalent to Euro III and Euro IV standards. [0003] Automobile exhaust gas analysis instrument is the hardware core of the exhaust gas detection system, a...

AI Technical Summary

Problems solved by technology

However, according to the market conditions of automobile exhaust detection products, the development of my country's automobile exhaust detection products and technologies is slow, and most of the problems are solved by importing expensive foreign products

At the same time, there is a lack of products that meet national standards and are suitable for promotion
