It is in global range, this is because automobile emission causes the increase of atmospheric greenhouse gas so as to cause global warming.
The doping of motor vehicle fuel, i.e. gasoline and diesel oil can cause pollutant increase and therewith to the severe of publilc health
Influence.Gasoline, which adulterates kerosene, can increase emission, this is because kerosene is more difficult to burn compared to gasoline, this can cause compared with
High-caliber HC, CO and PM.The sulphur of high-content can cause catalyst converter to inactivate in kerosene, reduce the pollution of conversion engine discharge
The ability of thing.The addition of kerosene can also result in the reduction of isooctane content, it can cause combustion knock.When gasoline adulterates diesel oil
During fuel, identical situation usually occurs when the diesel fuel grade of addition is relatively low.Diesel oil and kerosene are added in gasoline all
The formation of engine deposits will be increased.
Discharge standard is the requirement that pair amount of pollutant that can be discharged into environment establishes specific limitation.Many emission marks
Standard focuses on the pollutant that regulation is discharged by automobile (electric car) and other power cars, but they can also provide to come from work
Industry, power plant, the emission of mini-plant (such as grass trimmer and diesel-driven generator).The common strategy of emission standard is selected
It is technical standard.
Emission performance standard is limit value, it sets the threshold that different types of emission control technique may need to be higher than
Value.And emission performance standard is used to determine traditional pollutant, such as nitrogen oxides (NOx), oxysulfide (SOx), an oxidation
The limit value of carbon (CO), hydrocarbon (HC) and particulate matter (PM).
Various technologies for exhaust-gas treatment have been taken to observe stringent discharge standard.Exhaust gas includes pollutant,
Such as carbon monoxide (CO), hydrocarbon (HC), various nitrogen oxides (NOx) and oxysulfide (SOx).Different technologies are
Through the reduction for being employed to achieve variety classes pollutant.Some in these technologies include the use of filter, it is used for trapping
Particulate matter；Oxidation catalyzer, for reducing carbon monoxide and hydrocarbon；Selective catalytic reduction (SOC) method, for also
Former NOx or the like.
Sulphur in fuel is a problem for exhaust gas catalyzer, these exhaust gas catalyzers as DOC, (urge by oxidative diesel
Change device), DPF (diesel particulate filter), NSC (NOx storage catalyst converter) and analog.It can reduce these and urge
Change the efficiency of device.Catalyst converter needs continually to regenerate sulphur removal of making a return journey.Regeneration strategy is also based on the hypothesis amount of sulphur level in fuel.
There are the regulation of fuel quality, such as：In India, BS4 (Ba Late class 4s) fuel, its highest sulfur content can be with
It is 50ppm, in BS3 (bar drawing top grade level 3) fuel, it can be up to 350ppm.
In the country similar with India, BS4 and BS3 fuel can all use, and adjusting this strategy can be highly difficult.
If for example, BS5 (Ba Late class 5s) vehicle (DPF/DOC is housed) uses BS3 fuel, the at this moment sulfur regeneration frequency
It must just increase.There is presently no method instruction to show that control unit of engine (ECU) which type of fuel is in use.Phase
With ground, when using fuel is adulterated, it has the sulfur content higher than the limit value of defined, it is impossible to indicates ECU and changes regeneration
Frequency.
The content of the invention
The present invention as required by independent claims has following advantage.Apparatus and method of the present invention detects to add
The amount of thing, is contrasted with database, such as the sulphur concentration in the fuel of locality, notifies driver at the place
Fuel quality, and based on the fuel quality adjustment exhaust gas catalyzer regeneration frequency.Since it is set based on fuel quality
Regeneration frequency, the service life of exhaust gas catalyzer are also extended.
