Following strict Abgasgesetz could be met.The discharge of tri- kinds of nuisances of HC, CO, NOx will than gasoline car in exhaust gas from diesel vehicle
Few, its shortcoming is that soot particulate discharge capacity is higher than gasoline car discharge capacity in tail gas, or even is higher by tens times.Diesel emission
Solid pollutant be mainly particulate matter, it be by dry soot (SOOT), soluble organic fraction (SOF), a small amount of sulfuric acid and
Sulfate etc. is formed.With being continuously increased for global diesel vehicle yield, the exhaust emissions problem of diesel vehicle has caused each international politics
The great attention at mansion, worked out strict exhaust gas from diesel vehicle Abgasgesetz in succession both at home and abroad, as European Union respectively at 2005,2008
Year and 2013 implement Europe IV, Europe V and the exhaust gas from diesel vehicle discharge standard of Europe VI, and exhaust gas from diesel vehicle emissions concentration has been done sternly
Lattice provide；China also comes into effect state four, the exhaust gas from diesel vehicle discharge standard of state five in succession.Generally all it is to use to change both at home and abroad at present
Enter combustion technology combination selective catalytic reduction system operating (SCR) in engine machine, or combine gas recirculation system (EGR) and bavin
Oil machine particulate matter trap (DPF)/two big mainstream technology route of particulate matter catalyst converter (POC) exhaust aftertreatment technology comes real
It is existing.
Diesel engine DPF can effectively reduce Particulate Emission, but with the increase of distance travelled, increasing particle deposition
In trap, exhaust back pressure is caused to increase, the economy and dynamic property of engine deteriorate, it is therefore necessary in time by trapping
Combustible particle is disposed, and realizes the regeneration of particle trapper.Under the rotating speed and load of diesel engine normal work, delivery temperature one
As at 250~500 DEG C, and the burning-point of particulate is generally 550~600 DEG C, by the exhaust of diesel engine, it is difficult to make trap again
It is raw.Now universal dpf regeneration mode is that the particulate oxide that will be trapped in DPF is burnt, but this mode easily causes filtering body
Cause thermal damage, and the mode that cannot pass through because of particulate caused by lube oil additive bag, engine wear metal oxidizing fire removes,
Over time, this some particles gathers, and blocks DPF ducts, reduces DPF micro particle catching ability, meanwhile, cause to be vented
Pipe back pressure raises, and oil consumption increase, power reduce, and result even in DPF scaling loss and scrap, so as to cause Heavy environmental pollution and replacing
DPF economic loss.
