Description
Technical field
The utility model belongs to motor vehicle after-treatment system cleaning technique field, and in particular, to after a kind of motor vehicle
Manage System steam lavage apparatus.
Background technique
The main harm object of motor-vehicle tail-gas has carbon monoxide, hydrocarbon and oxynitrides etc. numerous poisonous and harmful
Gas.Their Producing reasons are mostly had due to caused by insufficient burning of fuel oil, and in the event of high temperatures,
More above-mentioned pernicious gases are more prone to produce, these pernicious gases can cause environment greatly to pollute, cause to human body
Respiratory system, blood, nervous system the important system of human body form great damage, and exhaust gas aftertreatment techniques of engine
Exactly it is used to slow down and solve the problem above-mentioned.
Exhaust gas aftertreatment system technical principle is to utilize reducing agent under the effect of the catalyst, by nitrogen in oxygen-enriched environment
Oxide selectivity reduction generates nitrogen and water.Specifically, the carbon monoxide (CO) and hydrocarbonization that Engine Exhaust Emission goes out
The product that object (HC) is not safe combustion is closed, will be generated when lack of air.The generation of oxynitrides (NOx) with start
The ignition temperature and oxygen content of machine have close relationship, and temperature is higher, and oxygen content is bigger, are more also easy to produce.These three pernicious gases
Composition is handled through the ternary catalyzing unit of one of exhaust gas aftertreatment system, and the catalyst in interior carrier occurs chemical reaction and is converted into
For harmless vapor, carbon dioxide and nitrogen, the above process is known as " three-element catalytic ".Ternary catalyzing unit is main to three kinds of automobile
The clearance rate of pollutant can reach the 90% of its total amount.
Anti-knock agent used in fuel oil for vehicles contains lead, manganese more, can not only cause greatly to pollute and damage to environment and human body
Evil, but also on the active surface for the lambda sensor and catalyst that can be deposited in ternary catalyzing unit, make lambda sensor " in
Also the purification efficiency of ternary catalyzing unit can be made to be greatly reduced while poison ", until damage.Have experiments have shown that, one case doped fuel
A new clothes ternary catalyzing unit can be made entirely ineffective.In addition the fuel oil of high sulfur content also results in catalyzed conversion preheating time and prolongs
The temperature that long, catalyst works improves and catalyst transformation efficiency reduces.
Solve ternary catalyzing unit Problem of Failure, usual way be the ternary catalyzing unit more renewed or carry out disassembly, cleaning,
But higher cost, and ternary catalyzing unit and surrounding automobile component may be damaged in disassembly process, while entire clear
Washed journey can cause secondary pollution to environment.
In addition, it can be to the ternary on car body in the prior art there are also a kind of ternary catalyzing unit cleaning machine of drip
Catalyst converter directly cleans, but this cleaning method is time-consuming, and the flow of cleaning agent is not easy to control, in cleaning process, needs artificial
Observation, operation, take time and effort, and easily generate damage to engine interior component, and cleaning effect is poor.
