Title: My astra is killing the planet
Post by: STEMO on 13 January 2020, 12:47:06
I've asked this question before, without receiving a satisfactory answer. How does a dpf stop particles being blown out of the exhaust when, surely, they must do it when self cleaning? Turns out they don't:

What you have to consider is that particulates are combustible (but have not been combusted in the cylinders).

So when the DPF regens, it gets very hot (circa 600 degrees C) and this combusts them, they can only pass through the DPF once burnt

I understand that, Mark, but the side product of that combustion still must be pretty unpleasant.

Mainly CO2 and water, not nearly as unpleasant as particulates and NOx

These reports are wrong, then? If so, they should be challenged by the industry because, as far as I can see, a rush back to petrol would see CO2 levels go through the roof.
It's no good suggesting to people like me that an EV would be the way to go, because I've nowhere to plug one in. Hybrids are a waste of time, in my opinion. The battery has to be charged by a petrol engine while driving along so, by working to both propel the vehicle and charge the battery, they are emitting more CO2 than by just driving. You don't get the battery energy for free.

As for the regenerative braking and charging going downhill, that wouldn't put enough charge in any hybrid I was driving. Nor Lord Opti, living in flat earth country.

Won’t be long before you ( your car ) are banned from city centres.  Mind you by then you will have an electric car.( charged wirelessly)

Back on the subject of regens, do some diesels do them without the driver noticing?

Most regen without any fuss. I know when my 2.0 astra with the fiat engine is doing it because the revs are at 950 instead of 850 at idle. I also know if I've switched off before the regen is complete because the cooling fans have to bring down the temperature of the dpf when you stop, and they go into hyperdrive  ;D
The wife's astra, with the GM 1.6 whisper engine, gives no indication whatsoever, and the fans never kick in when she switches off. It was the same with her Renault 1.5dci.

If you interrupt the regen cycle too often, a symbol lights on the dash and you get a message telling you to keep driving.
Title: Re: My astra is killing the planet
Post by: STEMO on 13 January 2020, 13:24:06
Far too complicated for the average commuter. As Nick W said, it's no use putting symbols, lights and messages on the dash, because people don't understand them, so there are scared of them, so they wouldn't sell many diesels.
And car salespeople will just quickly gloss over it.

I think in the future EV's will have a solar skin like a wrap, that will be suitably advanced to charge the battery even in a grim place on a grim day.  :y

Do the maths.....

The typical UK sunlight energy density is somewhere between 20W and 200W per square metre depending on time of year.

https://www.withouthotair.com/c6/page_38.shtml

A car is what? 2m wide and 4m long? So 8 sqM. Therefore the available energy hitting the car is somewhere in the 160W to 1.6kW range. At midday. On a sunny day.

GCSE question : Write your name in block capitals at the top of the paper...

O Level question...Modern Tesla cars use batteries in the 60-120KWh range. How long is it going to charge a 60KWh Tesla battery on a sunny noontime day in June.

AO/A level question...- it's only sunny 32% of the time in the UK (apparently). And sunlight distribution is basically raised Cosine distributed about noon. How long to reach 80% charge on a 120kwh battery in March?

Degree question : Where's the JCR/Student Union Bar?

All of this is, by and large, moot. People (me) will only adopt eco friendly cars* when we are forced to. Why? Well 1) It costs money 2) Most people realise that, even if this country turned zero emissions overnight, it wouldn't make a jot of difference to the world as a whole.

My diesel emits particulates which harm people on busy roads in densely populated areas, I don't live in such a place. A switch to petrol would mean emitting CO2, which kills the whole planet, apparently.

IMO, hybrids are not eco friendly cars.

Apparently solar power is no good (see above) so we could explore the idea of genetically engineering the trees to harvest wind power.  :y

Another advantage of tree houses is that you're not going to get flooded out.  :)

The bigger issue was NOx but, modern diesels with selective catalytic reaction plus AdBlue, output less NOx than petrols.

There are even a few new diesels (including one of ours), where the NOx levels are not even measurable.

All of this is, by and large, moot. People (me) will only adopt eco friendly cars* when we are forced to. Why? Well 1) It costs money 2) Most people realise that, even if this country turned zero emissions overnight, it wouldn't make a jot of difference to the world as a whole.

My diesel emits particulates which harm people on busy roads in densely populated areas, I don't live in such a place. A switch to petrol would mean emitting CO2, which kills the whole planet, apparently.

IMO, hybrids are not eco friendly cars.

Except it doesn't......thanks to the DPF.

The bigger issue was NOx but, modern diesels with selective catalytic reaction plus AdBlue, output less NOx than petrols.

There are even a few new diesels (including one of ours), where the NOx levels are not even measurable.

Blame the press and politicians who are jumping on a band wagon they don't understand
[/highlight]

Derv sales are still falling. :)
This is good news for those of us prepared to ignore the crap. Diesels are also getting cheaper.  :y

I'm trying to save the planet with petrol. :)

Just been on the phone with Mercedes Lincoln who want to sell me an  E63 estate in black. Only done 2200 miles.

I'm tempted. They are going to get back to me with a price. Car has been with them for 'some time' so probably want shot of it. Four wheel drive.  :y
Asian lad in corner shop tells me that the 63 is not 6.3 litres any more. It's a 4 litre twin turbo.

Citizen Khan is correct.

Originally a 6.3 litre N/A V8..........which became a 5.5 litre turbo V8.........now a paltry 4 litre V8, but with more power and torque.

That's progress for you. :)

Whatever happened to the concept of hydrogen-run cars? Surely we are many moons away from being able to have electric cars for everyone.

Hydrogen (from what I’ve read) is renewable with the only thing being emitted being water.

As said only what I’ve read but at face value looks the most promising.

And where do you suppose the Hydrogen is going to come from? Ok Hydrogen and Helium are the most common elements in the universe, but on Earth it's all tied up in other compounds - like water, or trees, or coal. To extract the Hydrogen requires energy - much more energy than you can get back by re-burning the extracted Hydrogen. Perpetual motion machines don't exist. It's much easier to extract energy (burn) from stuff like natural gas, oil, or coal because it comes out of the ground basically ready to go.

So at best you are moving the pollution from the point of fuel consumption (cars driving around cities) to the point of energy generation (power stations). If you can generate enough clean energy (solar, wind, hydro, thermal) to split enough water into H2 and O then fine it may work. But we're a long way from that at the moment.

and on top of all that, who would be daft enough to pay for the infrastructure to provide such an inefficient process? Refining oil into fuel is just as poor, but that grew slowly and provides a whole range of other useful chemicals.

There was a piece on the news last year/year before? where Honda[I think it was]had built a few Hydrogen powered cars for experimental purposes but were unwilling to commit to full production without the infrastructure being in place to fuel them.Of course the infrastructure suppliers wouldn't invest heavily in this until there was more demand from car owners buying them,so a bit of chicken and egg.It's easier and cheaper to install charging points for EVs as they're tapping into an already widespread network.
