Description
Technical field
The invention belongs to catalyst research preparing technical field, evaluating catalyst side in prepared by catalyst research is especially belonged to
Law technology field, is related to a kind of evaluating method of Catalysts for Motorcycles endurance quality.
Background technology
As Emission Regulation for Motorcycles Running is upgraded, motorcycle emission standard will be upgraded to state IV from state III, motorcycle state IV with
State Ⅲ emission standard is compared, and mainly has several respects difference：Transient condition increase, the increase of cold stage emission weight, emission limit
It is greatly lowered, durable mileage substantially increases.These differences propose requirements at the higher level to motorcycle emission control technology, particularly
To emission limit and the regulation of durability, the standard of state IV is set to turn into one of most stringent Emission Regulation for Motorcycles Running in the world.At present
Motorcycle is by installing three-way catalyst come the carbon monoxide (CO) in cleaning of off-gas simultaneously, the unburned hydrocarbon of oxidation
And three kinds of pollutants of nitrogen oxide NOx (HC).It is resistance to three-way catalyst that regulation is can be seen that from requirement of the regulation to durable mileage
Long performance requirement further provides for height, and three-way catalyst endurance quality evaluation method turns into the side that personage of the same trade pays close attention to jointly
To.Three-way catalyst durability evaluation typically uses quick aging method, by simulating the operating most severe condition of motorcycle
Carry out the inactivation of accelerator activator.
The principal element of influence motorcycle three-way catalyst endurance quality has durable temperature, endurance, durable air speed, resistance to
Long atmosphere etc., at present the method for conventional three-way catalyst aging mainly have vehicle aging, Muffle furnace aging, simulation gas aging and
Four kinds of engine pedestal aging.
Catalyst vehicle degradation, i.e., by road or rotary drum under defined operating mode as defined in operation standard in
Journey, then tests the emissions data of catalyst, judges whether emission result meets design object.Catalyst is carried out resistance to by vehicle
Long experiment need time length, it is costly, cause the catalyst plant man product R＆D cycle long, influence Catalysts for Motorcycles production and pin
Sell.With will putting into effect for new Abgasgesetz, the increase of durable mileage, former vehicle is durable to need the longer time just to obtain
Emission result is obtained, real vehicle is durable all to cause experiment to be difficult in cost, time and workload, and period is because of indivedual vehicles
Qualitative factor is easily caused whole long duration test and interrupted.
Catalyst Muffle furnace degradation is relatively common method, and advantage is that expense is low, efficiency is fast, has the disadvantage to urge after aging
The discharged nitrous oxides value of agent differs greatly with vehicle aging, and gas component does not meet actual conditions, it is impossible to which true and accurate is anti-
The nitrogen oxides of catalyst is answered to deteriorate performance；
Catalyst simulates gas degradation, can more accurately simulate aging gas part, temperature, time of catalyst etc. old
Change condition, is generally used for inquiring into the theoretical question related to catalyst reaction mechanism, is suitable for laboratory research and uses.Simulate gas
Body appraisement system not only needs to configure special source of the gas, and requires that the flow control to gas is very strict, to meet synthesis
Fixed proportioning is kept between gas, while the characteristics of simulating outlet part transient change, to control system it is also proposed that severe
Challenge.
Catalyst engine pedestal degradation, is present most widely used three-way catalyst aging evaluation method.Hair
Motivation stand quick aging has the advantages that the test period is short, experimentation cost is low and manpower demand is few, therefore, in the prior art
It is more the carry out Accelarated aging test by engine pedestal to three-way catalyst.At present had professional standard on
It is major requirement control excess air coefficient in the standard of the engine pedestal degradation of triple-effect catalytic unit, standard, air-fuel ratio, old
Change process temperature and air speed parameter to carry out stand aging to catalyst.In order to reach above-mentioned control targe, to shorten exploitation week

Ageing time, stand aging is carried out with the temperature and time calculated, and during catalyst is actually durable, temperature and time is
The factor of catalyst degradation is influenceed, but oxygen content influence is also in also other influences factor such as air speed, ageing process
It is quite obvious, therefore can not deterioration factor of the more real catalysts during vehicle is durable, the row of aging rear catalyst
Put result and the resistance to result error long afterwards of real vehicle is larger.
