Yep, Ducatti copied it and called it their own. Like I explained earlier tho, still has limitations inherent in cam design..(which its actually a variation of, the crown wheel us the cam)
But I get your drift .
Do Mazda still do the rotary Trochoid Duct motor? that seemed promising apart from seal tip problems.

Yep I believe so..RX7/8/9 still uses it. Very powerful but not efficient.
Herr Wankel I believe...

The European Union
And as for Freedoms disappearing, with the "Snooper's Charter" now law. you can forget Freedom too.
I am beginning to wonder if it is a good idea to continue posting to this forum because of your wonderful new internet laws. I am beginning to understand why the wicked witch wants free of the ECJ because the snoopers charter is definitely illegal under EU privacy law...

We only do this as a sort of Public service to prevent the Boys and Girls at Menwith Hill and GCHQ getting bored to death.
Let's show them a little human kindness and sympathy after all, imagine if your day was spent monitoring the Mobile Phone traffic and Facebook of the average brit?
They probably look forward to our efforts as "invigorating" compared to that and imagine the hours spent on their super computer to try and keep up with the convolutions, twists and turns of the reasoning processes employed by your fellow contributors?
I suspect they are taking bets which one of us is "one of them" if you know what I mean, (Nudge nudge, wink, wink!)

ICE is here for decades with plenty of improvements coming online.
No problem with that, I've posted as much myself. But you've ignored the type of hybrid ICE that I posted about which will increasingly take over, much more rapidly than you appear to think.

Car design and specification is increasingly being taken over by legislators as they tackle emissions and global warming worldwide. Even the Chinese are starting to get very serious, as we are in the west. Hybrid sales are expanding very rapidly at the cost of pure ICE, partly for the lower running costs, partly to avoid the penalties that higher polution vehicles are increasingly suffering. With current battery advances the hybrids will increasingly have ICE engines that only run after the battery pre-charge has been used, and then only at constant rates in generating mode. Sophisticated engines aren't needed for that, simple twin or three cylinder engines will be used, BMW already use a twin cylinder engine in that mode.

Problem encountered with e valve control has been reaction time. Un slower revving its fine...
Agreed, and thats the problem, modern efficiency has increasingly demanded ever higher revs. Not long ago red lines were around 5000 revs on production cars, but now 7000 has become commonplace. Magnetic latency and reaction times are major problems at those higher revs with solenoid operated valves. So the pure ICE cars are still predisposed to be more suited to existing valve operating methods. As said though, such cars will soon become much less important in the market.

You'll still be safe while in France though, regardless of what the British hold on you, since we'll be out of the EU.

Twin cylinder engines and a U2 battery?
BMW Drivers will be Revolting!
That will go down like a promise from Boris with them.

Not so! Just over 7 seconds 0 to 60 mph is pretty impressive for a moderate size family hatchback, when the ICE competition mostly take well over 10 seconds and often over 15 seconds.

BMW are clearly protecting their reputation with e-cars.

What BMW owner wants a car that goes like that
BUT DOESN'T ROAR?

Their Marketing boys are going to have a right old time to sell that one, especially if Clarkson is given one to drive!

(Will you stop being logical and talking sense? you've been told off about that before, remember we are talking BMW DRIVERS here.)

Sorry to depress you, but last year there was a waiting list and a lucky persion allocated one could sell it at over list!

Being a BMW driver can also take the form of one-upmanship since it can be about self-perception of a superiority, sort of "Look at me, aren't I amazing". Clarkson was impressed by the i3, rating it best electric as many others have done.

Not sure that's way things have gone for efficiency flecc. Higher an engine revs the more frictional losses etc. Modern efficient turbo engines ( eg ecoboost from ford) are quite low revving. Infact tendency has gone back ubdersquare for engine design..but generally engines are capable of revving higher when asked.

In the Hybrid.. Last year 26,000 were registered in uk along with 10,000 electric cars. That's out of just under 3 million... There is talk in many quarters of removing some of incentives for Hybrid/ ecars..and since we,ve now had both foe many years ( Leaf, Prius) can you really see an explosion in either,s numbers. ( Its running at well under 2% for both Hybrid and e)

Personally think had it being going to happen it would have done so vy now ???

1950 Norton Rotary Valve engine, we have been there and done that long a time ago
And of course the rotary crankcase valves of some two strokes and the twin piston two strokes of the sort promoted by EMC-Puch.

There's been many ways of induction without valve springs.

The designs are all much higher revving than yesteryear. You mention Ford, but they've dropped the slower revving series like the old 1.3 in favour of the high revving Zetec designs. Personally i think that's a pity, but it's the way the market leaders in engine design have gone.

Actually 2.69 million cars last year, boosted by the low sales during the recession so catch-up taking place. The natural level is close to 2 million.

There's a shift from incentives to penalties taking place. Incentives for hybrids are being reduced though generally retained for pure electric. But at the other end the polluters are being increasingly hit with low emission zones and much dearer driving.

Now a statement that might shock you into realising how big the changes can be. From this Autumn a London commuting driver of a higher polluting car like many diesels can change to a new Nissan Leaf fully electric completely free! Yes that's right, the new middle of the range £27,000 Leaf complete with 8 year warranty long range battery not only costing nothing but also saving them a fortune in fuel over the 8 years!

If they flog their existing car that just increases their bank balance still more by the thousands they get for it.

There is of course the possibility that after owning it for a while they did just that
"She is also quieter than a dead person, apart from when the petrol engine kicks in and starts to hum like a workshop compressor that’s overdone the Night Nurse.
And this, alas, is where the tide begins to turn.
Even though she is the first mini car I have experienced that is as easy to get in the back as the front (thanks to the rear-hinged coach-style doors), this huge plus is thwarted by one of the most ridiculous car industry innovations of all time.
But there’s an even bigger reason to pass on the i3. I kept a brief travel log to help me explain why.
Check out the distance, destinations and range for both the petrol engine and electric engine, whose two gauges tormented me sadistically the whole time I was behind the wheel.

5.05am. Home to Radio 2.
Distance 30.6 miles.
Petrol range 47 miles.
Battery range 54 miles.

I had the heater on as it was 1.5°C outside and I had the lights on because I didn’t want to die or get arrested for causing someone else to.

I had the radio on to see what my colleagues and the rest of the world was up to and I had the interior light on as I was writing this.

Just before I set off, my petrol miles went down to 46, and my electric miles went up to 55, even though I hadn’t moved an inch.
5.47am. Arrived Radio 2.
Petrol range 42 miles.
Battery range 28 miles

9.53am. Radio 2 to ITV
Distance 3.4 miles.
Petrol range 57 miles.
Battery range 24 miles.
All accessories turned off.

Arrive at ITV.
Petrol range 59 miles.
Battery range 19 miles.

12.09pm. ITV to home.
Distance 32 miles.
Petrol range 59 miles.
Battery range 18 miles.

Arrived at home.
Petrol range 47 miles.
Battery range 1 mile!
You get the idea?
It’s like spinning plates, not knowing what’s going to be left in which power source by the time you get to where you want to go – if you get there at all.
The next day I was leaving London on the A40 and had to turn round to go back into town unexpectedly, which caused me to question whether or not I should book a hotel room just in case.
The overall range capacity is so limited, even from max capacity, and the margin for error becomes exponentially more buttock-clenching with the passing of every mile.
On top of which, when I got home every day I had to find time I don’t really have to fill up with petrol, as well as plugging into the mains for a charge.
How I yearned instead for my single weekly visit to the service station.
I’m so sorry to report this car is almost marvellous, but in the end not at all.
She may well have killer looks and more than a touch of pep in her step, but she’s just bags more trouble than she’s worth, which, by the way, in BMW’s opinion is circa £40,000 for the model I tested.
Do yourself a favour. Forget about saving the planet – which you really can’t do – and save your money instead – which you really can.

Chris Evans.

Typical Chris Evans narrow minded idiocy, quoting worst case and also omitting the fact there's the range extender version with auxilliary charging engine.

Fact: The vast majority of all car journeys are far below the minimum range of the i3.

Fact: A high proportion of car owners never travel further than they could in an i3.

Fact: Many car owners have two cars in the household, one used exclusively locally, so that can be an i3.

Fact: The majority of UK car owners could do all their journeys with a range extender i3 version.

Of course the i3 won't suit those often who want to drive very long distances across the UK or travel intercontinentally, but they are a small proportion of car drivers. Those who want to drive a long distance only on rare occasions can hire for that.

It's not just Chris Evans who is silly in this way, all the professional car reviewers are guilty of being totally unrepresentative of the majority of the car driving population.

Brexodus the EU strikes back
Not alas a Movie this from Reuters
"
UK employers worry that EU workers will leave this year - survey
More than a quarter of employers in Britain say staff members from other European Union countries have considered leaving their firms or the country in 2017 after last year's Brexit vote, an industry group said on Monday.
The proportion rose to 43 percent of employers in education and 49 percent in healthcare sector employers, according to a survey of more than 1,000 companies conducted by the Chartered Institute of Personnel and Development.
The CIPD said Britain's labour market remained strong, but the decision by voters to leave the European Union was
likely to force companies to rethink their training strategies as they adjusted to having fewer EU workers in future.

aren't you pleased? in two years time, the appetite for taking back control will have to be strong enough for the tories to go through with the final phase of brexit.
