Impunity of a killer: Diesel diesel

[Flytox]

the right solution is to dilute the exhaust gas to cool it down and to cause the condensation of all the particles, then to filter with any simple filter like paper filter ... when it has been diluted to cool it is no longer need complicated filter like ceramics in the current fap ... simple paper is enough since the dilution has cooled down

From what I have read / understood, cooling the exhaust gases does allow the "condensation" / appearance of the particles, but I did not understand that it increases the size of the particles significantly enough that they can be filter effectively. The problem will therefore remain unresolved, we do not know how to trap the finest particles easily, economically without installation "untransportable" on a light vehicle (at least currently).

[Remundo]

perhaps to "bubble" the gases in a liquid; some of the particles could dissolve in it as the CO2 and other gases escape.

But it should change the liquid often (water in particular could increase the volume)

[chatelot16]

we do not know how to filter the fine particles when we pass only fine particles ... but if we give a paper filter enough particles bigger it ends up making a layer that also edges fine particles

so with my idea to suck a big flow of ambient air that will contain all the dust of the road, the filter will not miss particle of different size

another advantage the filter will suck chemically interesting ambient dust to absorb what is toxic in diesel exhausts

of course to suck a flow much larger than the exhaust will require a fan of a certain power, but not worse than the energy wasted for cleaning the current FAP

Another advantage is that the unburned hydrocarbon and other combustible dust that it comes from the engine or is picked up on the road will end in a useful way or dirty filters will be cremated! ... instead of being burned anyhow during the cleaning of the current fap

Éric Piolle wants to ban diesel in Grenoble on 2030 horizon

Thursday 1 March 2018 By Lionel Cariou, France Bleu Isère

This is a major public health issue for the mayor of Grenoble: he wants to "free" the Grenoble metropolitan area from diesel in 2030. Eric Piolle is thus following in Paris; the capital has set itself a 2024 target to phase out diesel.

..........
The mayor of Grenoble made the announcement this Thursday during the press conference initially scheduled to discuss the extension of the Restricted Circulation Zone (ZRC). It only concerns road hauliers and professionals. Since January 1, 2017, trucks built before 2001 and utility vehicles prior to 1997 no longer have access to the "ZCR" which corresponds to the "extended city center" of Grenoble. This ban is effective during the week, from 6 a.m. to 19 p.m. The Métropole Grenoble and the SMTC, the authority in charge of transport in the agglomeration, have announced an extension of the system.

First the ZCR will concern in spring 2019 not only the center of Grenoble but in all 9 municipalities of the agglomeration: Échirolles, Eybens, Grenoble, La Tronche, Poisat, Pont-de-Claix, Saint-Égrève, Saint-Martin -Le-Vinoux and Saint-Martin-d'Hères (the university domain is also part of the ZRC).

Then the restrictions on delivery vehicles will be gradually strengthened to achieve the prohibition of diesel in 2025.

2019

2001 pre-October diesel-powered delivery vehicles and 2006 pre-October diesel trucks will be banned (these vehicles correspond to the Crit'Air 5 sticker).

2020

Exit pre-2006 diesel utilities and pre-October 2009 diesel trucks (4 sticker #).

2022

Prohibition of diesel utility vehicles older than 2011 and petrol before 2006; prohibition of diesel trucks before 2014 and petrol before October 2009 (sticker n ° 3).

2025

Prohibition of utilities and diesel trucks as well as delivery vehicles older than 2011. Only will be allowed to ride the hybrid utilities or running on gas, as well as gasoline vehicles sold after the 1er January 2011. Hybrid or gas-powered trucks will also be allowed, as well as gasoline trucks put into circulation after the January 1er 2014er. Clearly, only delivery vehicles with the Crit'Air vignette 1 will be allowed to drive in the CRZ.

there are some who start to find adverse health effects of recycled tire pellets used in sports fields ... if these tire pellets are visibly toxic, the tire wear dust must be dangerous too, but invisible because we have all been subjected to it for a long time, no quick change having a visible effect

a filtering system on each vehicle that sucks in more air than the engine, will not only filter its own pollution but will also filter the pollution of others ... if such a filter retains only 50% of the finest particles this n it does not matter they will have a chance to be filtered by the next vehicle

I wonder if the best place to put the filter is on the vehicle ... we could put fixed filter in the cities to suck pollution of everyone ... fixed filter much more effective and economic than on the vehicles

Automotive: Bosch announces "revolution" in diesel technology
The group has developed a system that reduces nitrogen oxide emissions to a level up to ten times lower than the standards that will come into effect in 2020.

THE ECONOMY WORLD | 25.04.2018 Cécile Boutelet (Stuttgart, special correspondent)


The numbers seem too good to be true. On Wednesday April 25, Bosch, the world's largest automotive supplier, announced a major technological breakthrough on the diesel engine: the system developed by its engineers reduces nitrogen oxide (NOx) emissions to one level. up to ten times lower than the standards that will come into effect in 2020 and this, in real driving situation.

To convince suspicious observers, after months of controversies and scandals over diesel, Bosch invited them to drive a vehicle equipped with the new system through a course in Stuttgart and its hills at rush hour. The results are impressive: regardless of the time and type of driving, the values ​​recorded by the exhaust control system fired by the car are below the 40 mg NOx per kilometer, well below 168 mg currently required by law.

Minimum cost
According to the engineers who participated in the development, the new system does not involve expensive new parts, it is mainly based on a better organization of the engine and the smarter integration of parts already available in series. The additional cost of this system is minimal, assures the group, it can be immediately integrated with Euro 6 standard vehicles. "We want to put an end, once and for all, to the diesel debate," says Volkmar Denner, chairman of the group's executive board, who emphasizes the CO2 emission advantage, which would be lower than expected. 15% to those of a gasoline vehicle.

According to the group, a hundred engineers have been working for five years to develop this solution. And the group wants to go even further: thanks to the intervention of artificial intelligence, the engine could eventually have no impact on the air quality.

would not there be a water injection somewhere? In any case it corresponds to the results obtained by the Gillier-pantone system.

Reducing NOx "is very good" ... but what is the overall impact on emissions / pollution?
In these engines (petrol and diesel) as soon as you touch the engine parameters, all pollutant releases change in varying proportions (and possibly in contradictory directions).
In short, announcing a good figure on NOx not to mention CO, CO2, unburnt, consumption, particles (number and mass), associated, it does not mean that it is a global "environmental progress" ... Without a complete assessment it just looks like a publicity stunt.

I think more and more that the good filtering should not be in the car but in fixed thermal plants

Do not make the biomass thermal power plants far from cities ... you have to make thermal power plants in the city center and have them filter the most polluted air

replace all central heating boilers with optimized thermal plants to clean the air

and do not overload cars with gas plant efficiency already dubious when it's new, and even worse when it's old ... this content to make the car as light as possible to reduce consumption so the amount of pollution
