Description
Technical field
The utility model relates to a kind of automobile detection apparatus, specifically a kind of automobile emission gas analyzer sampler.
Background technology
Along with the development of auto industry and automobile pollution sharply increase, the pollutant of motor vehicle emission is one of consistent main pollution nuisance of urban atmosphere of generally acknowledging, has become serious social concern.Therefore, detect and control the concentration of automobile exhaust contaminant, becoming test item important in automotive check.
The pollutant of auto exhaust, mainly carbon monoxide (CO), hydrocarbon (HC), oxynitrides (NOx), sulfide (mainly SO2), soot and other-a little objectionable impurities.Under identical operating mode, CO, HC and the NOx discharge of gasoline exhaust are larger than diesel engine, and therefore, current Abgasgesetz mainly limits the discharge capacity of CO, HC and NOx to gasoline engine.The pollution of diesel engine to air is light compared with gasoline engine, mainly produces carbon smoke pollution, and therefore Abgasgesetz mainly limits the smoke intensity of diesel exhaust gas.
When GB/T3845-1993 " the measurement slack speed method of pollutant of gasoline engine exhaust gas " specifies that pollutant of gasoline engine exhaust gas detects, NDIR (NDIR) should be adopted, and concrete regulation has been carried out to detection operating mode and trace routine.Basic Cleaning Principle: the gases such as CO, HC, NO and CO2 in auto exhaust, has the character absorbing certain wavelength respectively to infrared ray, and has certain relation between the absorbed degree of infrared ray and exhaust gas concentration.Nondispersive infrared is exactly according to this principle, and namely the change of the certain wavelength infrared energy of waste gas absorption, detects the content of various pollutant in waste gas.When various gas mixes, this detection method has the impregnable feature of measured value.
Utilize the analyser that nondispersive infrared is made, both can make the single analysis instrument detecting separately CO or HC content, also can make the synthesis analyzer measuring these two kinds of gas contents.In exhaust, the concentration of CO directly measures, and the composition of HC emissions is very complicated, is re-used as the measured value of HC concentration after therefore the concentration conversion of various HC composition will being become the concentration of normal hexane (n-C6H14).
Carrying out analysis to vehicle exhaust to need to gather vehicle exhaust, is all manually utilize easy aspiration pump insertion gas outlet to extract a certain amount of gas the gas in aspiration pump to be entered in analyser at present again.This mode operational reliability is low, and hand sampling is unfavorable to the health of detection person, and the atomisation station gathered each time is different, also can have an impact to analysis result.
