Paris, Madrid, Athens, Mexico City Will Ban Diesel Vehicles By 2025 (bbc.com)

The mayors of four major global cities -- Paris, Mexico City, Madrid and Athens -- announced plans to stop the use of all diesel-powered cars and trucks by 2025. The leaders made their commitments in Mexico at a biennial meeting of city leaders. BBC reports: At the C40 meeting of urban leaders in Mexico, the four mayors declared that they would ban all diesel vehicles by 2025 and "commit to doing everything in their power to incentivize the use of electric, hydrogen and hybrid vehicles." "It is no secret that in Mexico City, we grapple with the twin problems of air pollution and traffic," said the city's mayor, Miguel Angel Mancera. "By expanding alternative transportation options like our Bus Rapid Transport and subway systems, while also investing in cycling infrastructure, we are working to ease congestion in our roadways and our lungs." Paris has already taken a series of steps to cut the impact of diesel cars and trucks. Vehicles registered before 1997 have already been banned from entering the city, with restrictions increasing each year until 2020. The use of diesel in transport has come under increasing scrutiny in recent years, as concerns about its impact on air quality have grown. The World Health Organization (WHO) says that around three million deaths every year are linked to exposure to outdoor air pollution. Diesel engines contribute to the problem in two key ways -- through the production of particulate matter (PM) and nitrogen oxides (NOx). Very fine soot PM can penetrate the lungs and can contribute to cardiovascular illness and death. Nitrogen oxides can help form ground level ozone and this can exacerbate breathing difficulties, even for people without a history of respiratory problems. The diesel ban is hugely significant. Carmakers will look at this decision and know it's just a matter of time before other city mayors follow suit.

      Hybrids do best at slow speed and stop-and-go traffic, i.e., urban areas. Often the internal combustion engine (ICE) kicks in once you're going faster than 40 kph, and especially on highways. I live in Toronto, and our local transit system (TTC) uses hybrid buses in the denser parts of the city (built pre-1930s) where stops are closer together and there are more lights. They tried using hybrids in the less dense parts (generally post-WW2) and found almost no fuel savings.

      If you're a in a rural area it's less likely you'll see these scenarios.

      At least this is how what I've noticed with past/current hybrids. New/future ones could change the drive profile as the technology is developed. And even if the ICE is engaged, they're getting better and better all the time. I own a 2003 Golf TDI that gets 40+ mpg, and at the time it was the only car that could do that, but nowadays there are a few 'petrol' ICE that can reach those numbers (of course diesels are now at 60 mpg).

      I live in the Parkdale neighbourhood of Toronto, which when it was built out in the 1880s was a "suburb" of the (then much smaller) city of Toronto. It was actually a separate town before it got amalgamated into Toronto in the 1890s. People would "commute" into the city.

      I've wondered about this too. I've noticed pollutants in emissions are measured in PPM - parts per million air molecules in the exhaust. Not in parts per distance traveled. So transportation efficiency (emissions per distance traveled) gets you nothing (volume of air ingested decreases with higher efficiency), and combustion efficiency (more energy produced per cylinder detonation) actually increases PPM even though in practical terms it would be offset by needing to fire the cylinder fewer times to get the same amount of work done. Meanwhile being able to run a lean mixture makes passing these emissions tests a breeze. Heck, you could rig up a bypass to feed intake air straight into the exhaust stream (probably illegal) and drop your PPM to near-zero.

It was always cleaner in terms of CO why it was lauded as better than petrol. Unfortunately it has far higher NOx emissions which more recently (recent in terms of a time scale of 50 years) has been linked to various ill health.

      This is not really true. The type of polution from engines is heavily influenced by politics. And politics determined that minimising CO2 was more important than the consequences for NOx. Diesel engines used to run without making ANY NOx. However, because of the political need to reduce CO2, they were modified to minimise CO2 regardless of the consequences for NOx.

      Well, congratulations, you got that completely and totally wrong. You could not be more wrong if you were trying to be wrong.

      First, NOx is produced any time you have combustion in the presence of nitrogen. Diesels produce more NOx than gassers because they have higher combustion temperatures. It's not unusual for someone to turn the fuel up on their diesel just a bit without understanding the consequences and melt a hole right in one of their fancy forged Aluminum pistons. This is why an exhaust gas pyrometer is a mandatory upgrade (if not fitted from the factory) for anyone who wants to increase power in their diesel. You can cook things very easily, mostly pistons and exhaust valves but also turbochargers.

      Second, gasoline engines produce just as much soot as diesels. They produce finer soot, which is more dangerous. The class of soot which gasoline engines produce is collectively termed "PM2.5" or particles of 2.5 microns and smaller. This is the smallest common classification of soot particles, and it is by far the most dangerous because these particles are so small that your cilia cannot sweep them out of your lungs. They can only be removed by adhering to sputum which is then expelled by coughing. Diesel catalysts re-burn diesel soot, which is nice big chunky particles of 10 microns or larger, until it too is PM2.5. This makes them look a lot cleaner, but it actually makes them much more hazardous to health.

      Diesels with clever injection systems but without catalysts are the most health-friendly internal combustion engines available which run on liquid fuels. The only internal combustion engines which are superior in that regard are propane engines (typically gasoline conversions, and not purpose-built) run on bio-methane, and lubricated with bio-based oil.

The study considered those hazards arising from the release of fuel from CNG vehicles ranging in size from a passenger sedan to a full size 53 passenger bus. The approach used was to compare the fuel hazard of CNG vehicles to the fuel hazard of gasoline vehicles. The risk was assessed by estimating the frequency of occurrence and the severity of the hazard. The methodology was a combination of analyzing accident data, performing a diffusion analysis of the gas released in the tunnel and determining the consequences of ignition. Diffusion analysis was performed using the TEMPEST code for various accident scenarios resulting in CNG release inside the Holland Tunnel. The study concluded that the overall hazard of CNG vehicles transiting a ventilated tunnel is less than the hazard from a comparable gasoline fueled vehicle. 134 refs., 23 figs., 24 tabs.

Currently this is mostly put into holding ponds to sit and stink for a time before being flushed into a waterway. The smart thing to do with it is put it into tanks (or even into glorified ziploc bags such as the ones often used as water tanks now) and let it cook itself, producing methane in the process; it's going to do this anyway, but we can capture it and put it directly into any vehicle with a propane conversion which involves an O2 sensor. You can buy the conversion parts (the PCM, injectors, and fuel rail) straight outta China for around five hundred bucks.

GE Energy Ventures owns a company called Gevo which would like to sell it to us, but Butamax sued them to stop production.

Like biodiesel produced by the transesterification of fats with methanol or ethanol it is a carbon-neutral fuel (assuming you get your conversion heat energy from a carbon-neutral source) but its other properties are more similar to petroleum diesel, like its gel point. It can be blended with 2-10% traditional biodiesel to deliver a fuel which can be used in any diesel engine and, which will actually extend the life of its fuel system with superior lubricity.

      The best solution for reducing emissions in locations where it is excessive, assuming we're going to keep driving around like a horde of motorized lemmings, is battery electric.

    There's two ways goods get delivered by truck in a city. One is the big semi comes right into town with its container. The other is that the semi goes to a transit hub somewhere around the periphery of the city and offloads its cargo into smaller trucks.

    In either case, the answer is simple: detach the container at a hub and have it taken into the city by an electric or hydrogen truck. Or just off-load the cargo onto a fleet of smaller trucks that meet the city's emission standards.

    This is not rocket science.

      You could probably switch to turbine-electric and burn... well, whatever you wanted really, but the only thing which would have the same kind of energy density is jet fuel. That would only cost what, an order of magnitude more or something? But the good news, everyone, is that we're all going to be getting higher-grade fuels whether we like it or not. It's not going to be possible to get much better emissions out of internal combustion vehicles without them. The automakers want to see even higher-grade diesel fuel, and higher-octane gasoline.

      Of course, if the Trump takes a Dump on CAFE somehow then we might well not get any of this stuff any time soon...

  23. Asshats "rolling coal" in the pickups... by Anonymous Coward · · Score: 0

    That's just dumb though. Banning something and forcing more cost and inefficiency into the system doesn't solve the problem. Although I guess in France, creating and protecting unnecessary or redundant jobs is kind of a priority.

    Say you have a large, quite efficient long-haul truck delivering its entire load to a superstore. You can drive directly to the superstore, unload and drive out, OR, you can drive it to some depot, spend time waiting and probably idling (creating additional emissions), spend more time and money unloading, reloading to lots of smaller trucks, all of which then drive in a long convoy to the superstore and then unload each one, drive them back to the depot, etc. Which option is less energy efficient? Which costs (significantly) more? Which creates significantly more road traffic ACTUALLY CAUSING MORE EMISSIONS FROM OTHER CARS THAT HAVE TO WAIT IN STOP-AND-GO TRAFFIC? Sure, you MIGHT be able to still reduce emissions slightly if you use essentially zero-emission small trucks, if the original truck was dirty enough and if the average traffic doesn't increase enough to drive emissions from other vehicles up too much (for example if you always do all deliveries in the middle of the night), but it still seems like having a hammer so looking at everything like a nail. I can think of several options that seem more efficient then just "lets ban X from Y."

    NOW, back to the subject line. I don't know if it happens in Europe, but around here there are a surprising number of total, absolute and utter asshats who buy full size pickup trucks and deliberately eff up the engines so they shoot a voluminous cloud of thick black smoke every time they even think of touching the accelerator. They drive up and down the street "rolling coal" as they call it, to demonstrate this ability, and there's not a damn thing the cops can do about it because there's an air quality law that makes it illegal for vehicles to produce visible emissions for more than a second or two, BUT, it doesn't apply to diesel vehicles. They can try to get them on "cruising" laws and "demonstration of speed" but under current laws in my state/city they can't get them for being gross polluters and possibly ending up killing asthma patients (and the rest of us, more slowly).

    If banning diesel vehicles in cities is what it takes to get those stupid selfish brainless morons off then roads, then despite the above, I guess I'm still provisionally in favor of it. They're THAT bad. Still I'd rather just have emissions laws tightened. And while they're at it, make noise laws apply to motorcycles, it's just plain stupid to deliberately make motorcycles so loud you need earplugs to ride them.

    I'm literally convinced that all of the following things (and probably more) have a direct inverse correlation to both brain size and reproductive anatomy size of the driver:

      - The amount of black smoke their truck spews out.
      - The height of their jacked-up vehicle.
      - The loudness of their vehicle's stereo when driving through residential neighborhoods.
      - The loudness of their motorcycle's muffler.
      - The amount of time they spend peeling out on dry pavement to be "cool." /RANT

    I am a supporter of alternative fuels but currently there is no choice. It will take time to introduce choice. Electric sounds great but it is totally impractical for many people who need their car for work. Who wants to stop for 2 hours to recharge every 2 hours while on a 6 hour drive? Not everybody has a garage where they can charge their car, most people just park in the street. Petrol does have some advantages over diesel but diesel also has many advantages over petrol. Hydrogen etc. are far too new to talk about. I hope that we will continue to advance but often these moves are counter productive. Currently the best option for most people that actually do have a garage is a hybrid which still uses fuel. Diesel prolongs the life of the vehicle and is not a fire hazard which makes it a better option in a hybrid. The electric BMW i3 has a petrol generator to double the range, would that be banned? I think that these ideas are jumping the gun and we should all calm down and start taking baby steps toward a better future in order to avoid throwing the baby out with the bath water.

      No, just misleading headline. They are not banning diesel cars, just requiring old cars to live up to newer standards if they want to drive in the city centers. So ban on really old particularly dirty diesels cars in the city centers, not a ban on diesels in general.
