KelvinD; that was part of the octane boost, an increased resistance to "pinking" or "knocking".

rogerg; nothing to do with lubricating the valve guides, that's what the engine oil is for. It was all to do with valve seat wear:

[QUOTE

Valve wear preventative[edit]

It is a common misconception that 'Tetraethyllead works as a buffer against microwelds forming between the hot exhaust valves and their seats.[14]' Once these valves reopen, the microwelds pull apart and leave the valves with a rough surface that would abrade the seats, leading to valve recession. When lead began to be phased out of motor fuel, the automotive industry began specifying hardened valve seats and upgraded exhaust valve materials to prevent valve recession without lead.[15]

Microwelding of the exhaust valve and valve seat is now thought to have occurred due to the increase of flame front speed when the switch to unleaded came about. The increased combustion pressures caused 'micro welding' in older style motors that had the valve seats machined into the cast iron head. Retarding the timing of the engines reduced the combustion pressures and proved to be an effective short term measure in the switch to unleaded fuel. The long term solution was hardened steel valve seats.[16]

The reason why there is now a requirement to register for settled status is because there was no registration requirements upon first entering the UK. Unlike everywhere else in Europe. Thus no-one has a clue how many came in. My suspicious mind tells me that that was by design, in order to quell the concerns about the numbers. Now all we can do is guess. Similarly no-one will ever know how many illegal migrants there are in the UK. How could you? By their very nature they are illegal so cannot and will not ever register their presence so just live on the black market and by crime. So population registers are now just approximate and always undercalculated. If there was a requirement to show your passport/ID papers etc., or something confirming your legal status to be there in order to do most things, again, like other countries, it would go a long way to helping the situation?

Kelly Hopper; in the past I would have strongly disagreed with you but now that there is such uncertainty about the actual number of people in the country I think it's time to introduce some proof of identity requirement when using services like the NHS.

Apparently some NHS hospitals do ask for proof of the patient having the right to live in the UK which surprised me as my family haven't been asked when visiting A&E over the last few years.

Thanks for the clarification on TEL. I knew it was an octane booster but because of the valve seat issue I mistakenly assumed it had lubrication properties also.

Avionker; you weren't alone!!

The human body also has a complete inability to get rid of TEL from the system so people who's birth post dates the banning of leaded fuel can be distinguished from their predecessors by the presence of TEL in their blood. Unless they fly piston engine aircraft which use UL91 or 100LL of course!!

LowNSlow, thanks for the info, I knew it stopped something wearing, just got the wrong bit. Anyway the Brexit thread was becoming boring now its all over for a while.

rogerg; do you think it's Brexity that we are stealing a march on the EU and banning carbon fuelled cars in 2035 rather than 2040?

The car manufacturers are going to have to get their collective fingers out to provide vehicles with a reasonable range and comparable cost by then....

Or since, as I thought I understood it, it was only the sale of new petrol, diesel or hybrid cars that is proposed to be stopped in 2035, there'll be an explosion of repair shops set up to keep cars with traditional engines on the road until they have finally rotted. UK roads could resemble Cuba by 2085 vehicle-wise with early 21st century relics continuing to populate our motorways.

ATNotts: I agree with what you are saying re keeping petrol/diesel cars on the road etc. However, there must surely come a tipping point at which the petrol companies won't be selling enough of the stuff to justify staying open and that will be the end of it?

How many fuel stations will there be after petrol/diesel vehicle production has been stopped for a few years? It could be rather like the same range anxiety that we have now with electric cars. Carrying cans in the boot?

I suspect there will be diesel on sale until haulage, farming and other heavy machinery industries find a way to replace their fleets too or at least until alternative fuels are found for combustion engines. Can you imagine a 20 tonne crane running on batteries?

Funnily a lot of the recent contributions have been about the past and what we are getting rid of, when a lot of The Same contributors have previously said how hard the future will be because of brexit.

Have we any idea what things will be like in 15 years time?

Electricity may not be available for all the world but letís not get disheartened.

Always look on the bright side of life.

I've been driving around in electric cars for a year and half now. The one I have now can pretty comfortably do around 250 miles or so in winter between charges, and in theory can do around 340 miles in warm weather (with a very light right foot). The technology exists, it's just a matter of bringing the price down and sorting out the charging infrastructure. Of the two, the latter is the biggest challenge, as the switch to electric cars pretty much kills the idea of conventional filling stations, as the vast majority of people charge almost exclusively at either their home or destination. To make this work for all those who don't have off-road parking means putting loads of charge points in, maybe on lamp posts. The power requirement isn't that massive, and the grid will be able to cope (it has a pretty hefty excess capacity at the moment, anyway).

Getting the rapid charging networks sorted will help. At the moment the only network that is dead easy to use is the Tesla one. Tesla have shown that charging at 200 to 250 kW works OK, and that sort of charge rate will add around 150 miles of range in ten minutes. I bet a fair few people stop for more than ten minutes on a long trip, where they might need to charge on route, anyway.

Petrol? Batteries? Diesel? In 20 years time, none of the above.

Fuel Cell technology will have overtaken them all as the source of propulsion power on the ground, in the air and on the oceans. Nothing else makes sense.

You saw it here first. If I'm wrong, please sellotape a note to my headstone telling me all about it.

Now back to poor old BoJo, already having to row back on his promises. All we can do is laugh a bit, and then hope that some good comes of it all when reality eventually guides the poor sod's decisions.

Laughing at Boris is fine. Unfortunately, that's where the humour ends because there's nothing amusing about the way the UK will begin to suffer shortly.

I only hope the "will of the people ", another from the hackneyed mantra's we used to hear on a frequent basis, prevails and he's forced out of office......along with the rest of his acolytes and one spad in particular follows him into oblivion .

I do have a very dry sense of humour actually, plus, I wasn't alone in seeing the light. I don't suppose for one minute, being suitably institutionalised, that you can see the future for the UK is going to be very different from the one promised in Boris's electioneering lies which were, after all, only intended to get Boris into No 10

You may be right about diesel being available but a local farm generates most of its own electricity so it will probably not be reliant on diesel. As for ancient cars using diesel, may be, but as now they can be legislated off the roads. Already they are excluded from city centres, Government could increase duty, and keeping one on the road becomes uneconomic.

Mine is 15 as was my previous car. It is comfortable achieves 40+, but it will cost more than its worth to fix its suspension. It cost the same last year too. Time to change.

"will of the people "
Clearly you have forgotten that there was an Election.

Cue dogma.
