Domain.
Background technology
Because engine cold starting stage ternary catalyzing unit can not reach operating temperature, engine cold starting stage hc discharges
Can not effectively be converted, control unit ecu needs increasing fuel emitted dose smoothly to start to ensure electromotor, in a large number in addition
Unburned fuel is discharged among air in the form of hc.Show according to relevant test result, in the test of nedc state of cyclic operation,
90% hc discharge results from the engine cold starting stage.Therefore, reduce engine cold starting stage dusty gass to discharge
Become internal combustion engine and continue one of development major issue urgently to be resolved hurrily.Adsorption technology adsorbs because of its cryogenic high pressure, high-temperature low-pressure solution
Attached feature, is a kind of effective means solving engine cold starting stage hc discharge.According to associated stand test result, in ring
Under conditions of border temperature is 20 DEG C, more than the 75% of engine cold starting stage hc discharge can be adsorbed on and placed adsorption material

Unit makes engine exhaust pass through adsorbent equipment by the opening and closing of valve, and after engine cold starting state terminates, control unit is led to
The opening and closing crossing valve makes engine exhaust pass through original exhaustor normally to discharge.However, this adsorbent equipment generally requires 2 arriving
3 extra valves in order to control engine exhaust through different pipelines, thus increased the complexity of whole adsorption system,
It is unfavorable for the application in engine cold starting emission control field for the adsorption technology.
Therefore, design one kind both can effectively reduce engine cold starting stage hc discharge, can realize adsorbing material again
Desorption and regeneration, and avoid the hc adsorbing that the problem that is desorbed in advance occurs, simplify adsorption system structure simultaneously, save automobile bottom
The adsorbent equipment of disk space seems particularly necessary.
