Cleaner air, who can be against that?


Recommended Posts

Now motorists face £20 fine if they leave their engine idling!

 

I have never seen this 'new' rule. It is in the Daily Mail, but its true, this rule can also be found on the legislation.gov.uk web site.

Define "idling".

 

Engines are subject to most wear at startup - an idling engine has essentially zero wear occurring.... so lots of restarts are not expecially good. Also if you are going to reheat a cat every time to stop and start, that's more pollution probably than just idling...

Once the engine is warmed up, my car shuts off the engine every time I stop.

 

It's called stop-start technology and is designed to save fuel.

I guess that is proof that it does save fuel, but the new rules are about parking in public places, car parks and at the side of the road, with the car stationary for longer periods, so people keeping warm with the engine running will be a thing of the past ;)

Yeah I have one of them as well.

 

I disable it first thing I did for the reasons noted about engine wear

 

Interesting article saying that newer cars with start-stop technology suffer no more wear than cars without it:

Down to improved low friction materials being used, better lubricants etc. I don't have it on my car and I suspect it would actually put me off a car with it, however that's down to prejudice on my part and not science!

You get used to it. After a while.

Actually it's most designed to cheat the emissions test and get the car a better rating.

 

One part of the emissions test just basically involves driving and coming to a stop, then waiting (simulating pulling upto a junction maybe?)

If the car shuts it'self down when it comes to a stop then it's total emissions for that part of the test are amazing (because the engine is not running)

 

The difference stop-start makes to the emissions banding is quite significant, even on like for like engines/vehicles.

 

There is a slight fuel advantage, but it's very specific and usually only for cars sat for long periods in heavy traffic.
