C'est sa tu fais partie de ceux qui croit que les filtres a particules sont une conspiration pour faire consommer plus...
Y'a des villes en Europe que tu n'as pas le droit de circuler si ton diesel a pas de filtre a particule.... Le surplus de carburant brulé pour la regénération du filtre est moins poluant que de consommer moins SANS filtre a particule. L'exemple du catalyseur est une analogie pour ceux qui savent pas comment fonctionne les dpf sur un diesel, rien a voir coté technique. Et NON sa double pas ta consomation et comme j'ai dis, le surplus de diesel que sa prend pour régénerer le filtre est moins poluant que de rouler sans filtre.
Les particules rejetés sont hautement cancérigene, et c'est pas un autre histoire, c'est un des enjeux principals.
Donc tu crois fermement que les filtres a particules sont nocif pour l'environnement?? C'est ce que tu dis??
First of all, just to show how unknowledgeable you are and why you should keep quiet, only particulate matter under 100ym enter the bloodtream via the pulmonary alveolus, therefore, only those are carcinogen because the rest of them get filtred like any other dust. Particulate matter is also a hydrocarbon (HC), therefore, it does not cause ozone depletion or anything like that in fact, those hyrocarbons ar heavy enough that they settle down on the ground.... Also, it is a fact that you have to burn extra fuel to regenerate the filter so do not tell me that the fuel consumption is the same however, that extra combustion releases all that : Diesel engines produce very little carbon monoxide as they burn the fuel in excess air even at full load, at which point the quantity of fuel injected per cycle is still about 50 percent lean of stoichiometric.
This is a list of chemical components that have been found in diesel exhaust.
Contaminant Note
acetaldehyde IARC Group 2B carcinogens
acrolein IARC Group 3 carcinogens
aniline IARC Group 3 carcinogens
antimony compounds Toxicity similar to arsenic poisoning
arsenic IARC Group 1 Carcinogens, endocrine disruptor
benzene IARC Group 1 Carcinogens
beryllium compounds IARC Group 1 Carcinogens
biphenyl It has mild toxicity.
bis(2-ethylhexyl)phthalate endocrine disruptor
1,3-butadiene IARC Group 2A carcinogens
cadmium IARC Group 1 Carcinogens, endocrine disruptor
chlorine
chlorobenzene It has "low to moderate" toxicity.
chromium compounds IARC Group 3 carcinogens
cobalt compounds

All of that highly toxic and detrimental stuff is added to the air, to burn failry harmless visible carbon (soot). The tradeoff is complety fucking madness, its like amputating the entire body to the neck for an ingrown nail....
Now, since science is all wrong and mike is all right, please show me the very thorough research you've done to prove that chemistry has actually been all wrong all that time...
And also, provide me with the name of just a single city where every diesel engine has to have a particulate filter... anywhere in the world. And I want the actual law here, not just hearsay since that seems to be your forte. Then you might have some credibility. By the way, wiki says : While no jurisdiction has explicitly made filters mandatory, the increasingly stringent emissions regulations that engine manufactures must meet mean that eventually all on-road diesel engines will be fitted with them. In the European Union, filters are expected to be necessary to meet Euro.VI heavy truck engine emissions regulations currently under discussion and planned for the 2012-2013 time frame. PSA Peugeot Citroën was the first company to make them standard fit on passenger cars in 2000, in anticipation of the future Euro V regulations.
Just sayin....
