Are they banned now!

When did the emission controls come in?

Not banned, but difficult to get within the regs.

It’s been happening for years. I think it was the Euro 3 regs that killed the RS250 for example.

I suppose they decided at that point that the market was too small to invest in technology and design elements that would improve the emissions output and the gig was up.

Why are PHEVs nearly exclusively petrol EV why not a tiny diesel and EV ? Commercial offerings is Railways are derv units not petrol.

pretty sure railways don't pay for DERV with the higher tax (diesel engine road vehicle)

Farmers certainly don't - they have "Red Diesel" which is a lower rate tax diesel with a red dye ostensibly to stop them using it in their road cars as well. Like they don't.

It used to be that pleasure boats (ie. yachts, motor cruisers, and speed boats) were allowed to use red diesel too. Then the rules changed and the cost of boating skyrocketed from "bloody expensive" to "OMG how much?"

I'm sure I read something a few years back that there were a few reasons that hybrids tend be petrol rather than diesel.

The main one is probably that most of the world hates diesel and a small petrol engine is cleaner for cities.

Another was that small diesels don't lend themselves to being stopped and started frequently and until they're up to temperature arnt very efficient.

Did Bryan Adams really buy his first real six-string from the five and dime?

Yes. In the Exx Days there (mostly) was the 1, 3, 5, 6, 7, and 8 series, with a few other (Z, X series, et al).

Then BMW decided to start giving their different body styles different E numbers. The fourth generation 3 series had one code. The E46. When the fifth generation came out, there was 4 codes. The E90 (saloon), the E91 (touring), E92 (coupe), and E93 (cabriolet). This happened across the board, and more models, They ran out. With the F series there are just so many. With BMW now having the 1, 2, 3, 4, 5, 6, 7, 8, Z, X, and i models of most of these, there are just so many. So in short, I would say yes. Yes they did.

Of course. Didn't realise they'd get to the ton so quickly though.
As a previous owner of an E86 Coupe ( as opposed to an E85 roadster) I should have realised that.

Don't know but he was 11 when he did it

In Tesco today, 3 down in a queue. Bored AF, I was watching customers ahead shopping being scanned. items were scanned, and periodically the belt moved till-wards. How does it know when to do this, weight sensors under the belt, knowing to move the belt onwards?

How about a foot pedal under the counter ?

I wondered, but deemed it unlikely. I nearly asked the cashier, but she looked too pissed off at being on her shift

Resistance sensor at the end of the belt detects when an item has hit the end, probably.

I think older systems used an optoelectric sensor.

Again, I wondered this, but items were often picked and bagged, before the belt end was clear, When it was it moved.

Look at the side rail of the belt at the end, there's usually a small hole visible which houses a sensor

That’s what I would have thought too.

Surely it can't be anything to do with weight as some items you can buy in Tesco must weigh many times the weight of others. It never occurred to me that it was anything other than a cashier-operated foot switch.

Much as it goes against the grain to agree with anything Frank says.

This, there's a laser at the end of the conveyor. When it's broken the conveyor stops.

Which is why those separators for different peoples shopping work to stop the conveyor, and its appreciated that you have one after you if you are the last person...

[talksthetorque]

Mart G is correct.
A send and receive sensor in the hole at the cashier end of the raisedmetal strip where the “next customer” separators go. Reflector opposite.
No lighty?
No movey.

It’s usually just a light beam at the cashier end of the belt. As the cashier takes the item breaking the beam, it moves along until the next item breaks the beam and it stops again.

That is the primary belt feed controller, but Tesco also have a secondary, cashier controlled, system. Effectively a manual control. One of the few supermarkets where you'll occasionally see the belt not move forward automatically, when the cashier has forgotten to switch back to auto.
