Description
Technical field
The present invention relates to the regeneration of the exhaust gas catalyzer based on fuel quality.
Background technique
Since the industrial revolution starts, atmospheric pollution is because the use of fossil fuel increases and rapid development fast.Particularly, automobile industry has become the main consumer of fuel oil, and air-polluting main contributions person.In this question essence, be in global range, thereby this is because automobile emission causes the increase of atmosphere percent of greenhouse gases to cause global warming.
The doping of automotive fuel, i.e. gasoline and diesel oil can cause the increase of pollutant and the baneful influence to publilc health thereupon.The gasoline kerosene that adulterating can increase effulent, and this is that this can cause HC, CO and the PM of higher level because kerosene is difficult to burning more than gasoline.In kerosene, the sulphur of high-load can make catalyst converter inactivation, reduces the ability of the pollutant that transforms motor discharge.The interpolation of kerosene also can cause the reduction of octane content, and it can cause engine knock.In the time that gasoline is adulterating diesel fuel, identical situation occurs conventionally in the time that the diesel fuel grade of adding is lower.Diesel oil and kerosene add the formation that all will increase engine deposits in gasoline to.
Emission standard is the requirement that the amount of pollutant to being discharged in environment is set up specific limited.Many effulent standards are paid close attention to the pollutant of regulation by automobile (electric motor car) and the discharge of other power cars, but they also can stipulate for example, effulent from industry, power station, mini-plant (mowing machine and diesel generator).Common policy selection to effulent standard is technical standard.
Effulent performance standard is limit value, its set dissimilar emission control technique may higher than threshold value.And effulent performance standard is used for determining the limit value of traditional pollutant, for example nitrogen oxide (NOx), oxysulfide (SOx), carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM).
Various technology for waste gas treatment have been taked to observe strict emission standard.Waste gas comprises pollutant, for example carbon monoxide (CO), hydrocarbon (HC), various nitrogen oxide (NOx) and oxysulfide (SOx).Different technology has been used to realize the reduction of variety classes pollutant.Some in these technology comprise use filter, and it is used for trap particulate matter; Oxidation catalyzer, is used for reducing carbon monoxide and hydrocarbon; Selective catalytic reduction (SOC) method, is used for reducing NOx or analog.
Sulphur in fuel is a problem for exhaust gas catalyzer, and these exhaust gas catalyzers are as DOC (diesel oxidation catalyst), DPF (diesel particulate filter), NSC (NOx storage catalyst converter) and analog.It can reduce the efficiency of these catalyst converters.The catalyst converter sulphur removal of making a return journey of need to regenerating continually.Regeneration strategy is also the supposition amount based on sulphur level in fuel.
There is the regulation of fuel quality, for example: in India, BS4 (Ba Late class 4) fuel, its high sulfur content can be 50ppm, in BS3 (bar draws top grade level 3) fuel, it can be up to 350ppm.
In the country similar with India, BS4 and BS3 fuel are all operable, and adjusting this strategy can be very difficult.For example, if BS5 (Ba Late class 5) vehicle (DPF/DOC is housed) uses BS3 fuel, at this moment described sulfur regeneration frequency just must increase.Also have no idea fuel that indication shows which kind of type of control unit of engine (ECU) at present in use.In the same manner, when using doping fuel, it has the Sulpher content higher than the limit value of defined, can not indicate ECU and change regeneration frequency.
Summary of the invention
The present invention as desired in independent claims has following advantage.Apparatus and method of the present invention detect the amount of affix, contrast with database, and for example, for the sulphur concentration of the fuel of locality, driver is at the fuel quality at this place place, and adjust the regeneration frequency of exhaust gas catalyzer based on this fuel quality.Because it sets regeneration frequency based on fuel quality, the life-span of exhaust gas catalyzer is also extended.
