Hello

precisely, it is very easy in a vehicle to add a small percentage of SP95 or E85 in diesel, for a boiler, what exactly is it, has anyone already tried this additive?

would a TCB test have been done for a system equipped with a particle filter, I will be curious to see the result.

yes, there is a particulate filter, but when is there gas? acidity, so2, that's why I launched the idea of ​​a gas washer (pH regulator type)

re

it is on that there are other gases produced during combustion, but if the combustion is too incomplete, the proportion is more or less high, I presume because knowing nothing on this side there, I do not I won't risk proposing something, just what I know or guess.

what matters above all is the quality of the combustion, ultimately it will determine the quantity of product that we have to use.

Poisoned by nitrogen dioxide, London goes to war against diesel

THE WORLD | 31.07.2014

For Claudia, the current hot summer days are the worst. The souvenir seller, located on Oxford Street, in the heart of London, can hardly breathe in the smoke of the buses and taxis that parade through the street. “If I wear a white garment, it is black at the end of the day. When I breathe, I feel like I have dust at the back of my throat, and my nose is constantly blocked. »

This shopping artery is the most polluted in the British capital. And maybe of the world, in front of those of Beijing. According to David Carslaw, an air quality specialist at King's College University, the concentration of nitrogen dioxide (NO2) emitted by the exhaust pipes of diesel vehicles is exceptional.
The annual average concentration reaches 135 micrograms per cubic meter, three times the maximum authorized by European standards. "To my knowledge, it's the highest level in the world," says Carslaw.

“A CHALLENGE THAT IT IS URGENT TO TAKE UP”

Tuesday July 29, London decided to react. Its mayor, the thunderous Boris Johnson, announced the creation for 2020 of an “ultra-low emissions” zone in the downtown area. Objective: to drive out the vast majority of diesel vehicles. "Improving air quality is an urgent challenge," said Johnson.

He plans to charge very dear for old diesel vehicles that want to enter the city center. Since 2003, there is already an urban toll, currently 15 euros per day, for all vehicles entering this area. From 2020, Mr. Johnson wants to double this amount for diesel that does not meet the new pollution standards. A price which should be sufficiently dissuasive to repel the vast majority of private cars.

This measure will concern diesel vehicles which will not comply with the so-called “Euro 6” standard. This standard, intended to reduce emissions of pollutants, particularly nitrogen dioxide, will come into force in September throughout the European Union. Clearly, all cars sold beyond this date will not be affected by the doubling of the urban toll.

At the same time, Mr. Johnson announces that by 2020, all buses will have hybrid or fully electric engines. As for taxis - which run on diesel - they will have to run on electricity on the most polluted roads, such as Oxford Street.

If Mr. Johnson has decided to act against pollution, it is because there is an emergency. Last year, the British Supreme Court convicted the government for failing to meet nitrogen dioxide standards. In February, the European Commission decided to take the United Kingdom to the European Court of Justice.

However, London has little to do with Mexico City or Beijing, where pollution is much higher in terms of fine particles or carbon monoxide. The air has greatly improved since the disappearance of coal heaters, responsible for the famous smog, the fog that characterized London until the 1950s. But the city has a specific problem concerning nitrogen dioxide.

CONSTANTLY INCREASING POLLUTION

The explanation is found in the fight against another pollutant: fine particles, extremely harmful to health. To burn them better, London buses have been equipped with technology that produces an excess of NO2. This improved their combustion but caused another pollution. "All in all, it's probably a good choice, because fine particles are more harmful to health than nitrogen dioxide," said Carslaw.

NO2 pollution is particularly severe in streets like Oxford Street, where many buses pass. But, in the rest of the capital, it is not much better, especially since traffic is constantly increasing, despite the implementation of the urban toll.

So much so that there have been many criticisms of the ultra-low emission zone project. Elected officials and associations believe that Mr. Johnson does not go far enough. "Poor air quality is a silent killer, which causes 29 premature deaths a year," said Julian Bell, city councilor who heads the transportation and environment committee. The area needs to be established earlier, and over a larger area. "

Boris Johnson, who is not one to disassemble himself, replies that, thanks to his policy, London will soon "look the cleanest in Europe, except perhaps in the Alps". Before going on: "Who knows, maybe one day we will come from the countryside to breathe the fresh air of our city. We are far from it.

Air pollution: Senate plans to prosecute a pulmonologist who lied to him

AFP March 18 2016

The Senate plans to prosecute the pulmonologist Michel Aubier who lied to his commission of inquiry on the cost of air pollution by declaring under oath that he had no connection with the petroleum industry, said the rapporteur on Friday. the commission, Leila Aïchi (Ecologist), confirming information from Le Monde.

Thursday, Mr. Aubier, head of service at the Bichat hospital in Paris, acknowledged before the commission which had met exceptionally behind closed doors after rreleases from Liberation and the Duck in chains that he had received from 50.000 to 60.000 euros per year from the oil group Total since the late 1990s.

"I have no link of interest with economic players," however, Mr Aubier declared on April 16, 2015 before the committee. He had just sworn to "tell the whole truth, nothing but the truth", raising his right hand.

False testimony before the commission is punishable by up to 5 years' imprisonment and a fine of 75.000 euros.

Mr. Aubier was asked about the way in which the Assistance Publique-Hôpitaux de Paris apprehends the question of the economic and financial costs of air pollution, in particular by treating the pathologies linked to it.

The commission, which also heard the president of the AP-HP Martin Hirsch, asked the president of the Senate Gérard Larcher to seize the office of the Senate which should decide on April 28 to prosecute or not.

"This lie is all the more inadmissible as it concerns a question of public health," said Aïchi.

In July, at the end of its work, the commission chaired by Jean-François Husson (Les Républicains) had concluded that air pollution would cost France more than 100 billion euros per year, in health costs , absenteeism in companies or lower agricultural yields.

She had recommended 61 measures for "a real ecological taxation" and to "supplement existing standards". In transport, she proposed in particular the gradual alignment until 2020 of the taxation of gasoline and diesel, and the establishment of a tax on nitrogen, nitrogen oxide and fine particles.

Yes, the tree that hides the forest. There is nothing for Tautale, they pollute, promote pollution, finance crooks in various commissions, corrupt our politicards by funding political campaigns and other cop21.
Aubier and the other large pests deserve to be locked up 2 meters from the ring road "in the open" for the rest of their lives.
