The soot trap

A video by the max Planck Society from 2006 regarding the research into the reduction of soot from diesel-fueled vehicles. Source- http://www.mpg.de/english/illustrationsDocumentation/multimedia/scienceMovies...

'Manufacturers of diesel-fueled vehicles are working feverishly on a filter concept that will decrease the emission of diesel soot. Standard impedance filters can, over time, become clogged and must then be regenerated. This requires additives and additional maintenance time and costs.

During the course of a joint project, scientists at the Fritz Haber Institute of the Max Planck Society have discovered that soot particles from modern commercial vehicle motors are structured in a totally different manner than has been generally assumed: Through improved combustion, substantially smaller, fullerene-like soot particles are formed. These are much more reactive than soot from earlier generations of engines and can therefore be broken down through the nitrogen oxide that is contained in exhaust.

Based on the basic researchers' findings, engineers at filter manufacturer EMITEC and MAN Nutzfahrzeuge AG have developed a new, open system that does not have to rely on renewal and additives: The "soot trap" holds back the soot particles long enough until they have been burned off by the nitrogen oxide of the exhaust and turned into carbon dioxide. The expulsion of soot is consequently reduced by up to 90 percent.'

THIS IS STUPID! LET THE DIESELS SMOKE!

@ortcutt These systems use a lot of fuel to regenerate. that's why a lot of people are against it. Less soot=more Fuel and C02. Not the best solution

[tadaa11]

@ortcutt

Yes, I do. Why not require that all DPFs are Passive regeneration? Then people wouldn't have to burn 35% more fuel, and emit 35% more C02 I might add, to have less diesel particulates. Its a freaking loophole to please you hippy naysayers and it obviously is working.

[ortcutt]

@tadaa11 Do you have another proposal for preventing the particular emissions?

[ortcutt]

@finalfantasyXyuna Yeah, let's all get asthma and heart disease. Why do people say stupid things like this?

[knaussbrad]

@finalfantasyXyuna yay

lets clean the air !!

any improvements is a MAJOR improvements !!

nice video. enjoyed that. thx
