And a kind of device for carrying out purified treatment to exhaust gas during motor-vehicle tail-gas environmental protection tests or auto repair.
Background technique
Motor vehicle emission refer to the CO (carbon monoxide) being discharged from exhaust gas, HC+NOx (hydrocarbon and nitrogen oxides),
The pernicious gases such as PM (particle, soot).They are all the pernicious gases that engine generates in burning work.These are harmful
Gas Producing reason is different, and CO is that fuel oil aoxidizes incomplete intermediate product, and CO, gaseous mixture can be generated when oxygen is inadequate
Concentration is big and gaseous mixture unevenly can all be such that the CO in exhaust increases.HC is unburned substance in fuel, not due to gaseous mixture
Uniformly, the reasons such as chamber wall is cold cause part fuel oil to have not enough time to burning to be just discharged away.NOx is that fuel (gasoline) is firing
A kind of substance generated during burning.A kind of substance that anoxic generates when PM is also fuel burning, wherein most obvious with diesel engine.
Whether vehicle discharge is up to standard, and final authoritative department is responsible for the environmental protection administration of automobile emission gas analyzer using simple work
Condition method or lug down method detect it, detect underproof motor vehicle for exhaust pollution, repair through the maintenance of related enterprise
It is rechecked after reason, only can just be come into the market normal operation in the motor vehicle that reinspection reaches requirement, and environmental protection administration is motor-driven
Tail gas detection usually may require that vehicle driver person according to the requirement of detection teacher, to automobile under different operating conditions
Tail gas is detected, to assess whether it complies with standard, and in this process, in order to reach different detection effects
