Description
Technical field
The utility model belongs to automobile emission gas analyzer technical field, and in particular to a kind of motor vehicle exhaust emission flow rate detection dress
It puts.
Background technology
Containing a large amount of toxic and harmful gas in vehicle exhaust, this is most directly also most apparent.Population is close in city
Degree is big, and the quantity of vehicle is also more, and the tail gas of discharge is also just more, it is easier to and human body is caused to be directly sucked in a large amount of tail gas, is that human body baffles,
It gives rise to diseases, even results in the death of people.Containing a large amount of carbon dioxide in emission, greenhouse effects have more been aggravated.
Automobile emissions standards refer to CO (carbon monoxide), HC+NOx (hydrocarbon and the nitrogen in order to which automobile is inhibited to be discharged from exhaust gas
Oxide), the generations of the pernicious gases such as PM (particle, soot), the standard that country formulates.
While controlling automobile exhaust gas quality, it is also necessary to unite to the gas exhaust amount of vehicle exhaust
Meter planning, it is therefore desirable to be measured to the gas flow rate of vehicle exhaust, common survey device is all directly to be adopted by air gauge
Collect the pressure in air-flow, so as to carry out calculating gas flow rate by Bernoulli Jacob's gas pressure and high flow rate relation formula.Air gauge directly measures
Mode, volume is larger, in automobile exhaust pipe, operating difficulties, and easily influence automobile normal exhaust, measurement data
It is inaccurate；The dust moisture in automobile exhaust pipe or greasy dirt are easy to corrosion measuring device simultaneously, reduce the service life.
Therefore need to propose a kind of easy to operate, when measurement does not influence automobile normal exhaust, and the automobile of service life length
Exhaust emissions flow monitor.
