A total mystery, why would you let an engine idle, and why would you let an engine idle in an M.S.A when drivers are trying to sleep.A modern engine does not require to be run prior to use or does it need to be left to idle after prolonged use.
My bike produces 100 B.H.P from 599cc at 15,500 rpm do I fanny about with it, no I don’t.
Don’t you let it warm up?

In my experience it’s a “don’t give a toss not my fuel” attitude, one of my pet hates as well.
They use a litre an hour. I doubt in a week they’d use more than a litre and a half of fuel. Doing 10 miles into a headwind will waste more fuel than that.

It does if it has a turbo and you want the turbo to last. On a lot of wagons I’ve driven there’s even been a sticker on the window saying not to shut off straight away.

CBR6?
In Finland your not allowed to let your engine idle for more than 2 minutes, unless it colder than -15 in which case your allowed 4 minutes (woohoo.) If they can do it in their climate i’m sure we can

Yep I never whack a cold engine, an engine won’t warm on tickover it needs to worked, leaving an engine idling will do more harm than good.

Our buses switch themselves off after 5 minutes.
in a previous life the firm i worked for had a contract with TWM to apply an anti graffiti coating to their new buses.
as it was winter the upstairs deck used to have frozen codensation on the headlining and this coating became volatile if mixed with water.
i drew the short straw, so my job was to go to the depot and find the 6 buses we were doing that day, and then runaround restarting them every 5 minutes for 2hrs to warm them up before the rest of the guys turned up!

Just flogged my RF9, 125bhp around 10,000rpm - 135bhp around 11,000 rpm depending who you believe, but mine had a dyno-jet kit, sports exhaust, K&N panel filter (not the induction kit, screwed up the air / fuel mixture on my last one) and changed the gearing via sprockets, went off the clock which had 190mph on it, was only doing 171mph though according to the speed camera, gutted, thought I’d be in the 200mph club.
Erm, back to OP, My car feels restricted until the temp guage moves, doesn’t have to be in the middle, but it has to come off the bottom.

A weight on the accelerator to push the revs up slightly usually confuses these infernal devices.
maybe some people like to allow time for the oil to get round.
they may have a small air leak, but rather than reving the arse off it, they just let it tick over.
if it bothers you so much, then i think you’ve chosen the wrong occupation.
This has been done on here many times. Personally I run it for 60 seconds before pulling away in the morning and switch it off after about 20 secs when stopping for the night. This is ample, all this bobbins about turbos and oil circulation & other techno jibberish is bs if u ask me, just don’t rag the bejeesus off it the moment you pull off in the morning.
I can handle people running them for a couple of mins, or as long as they want if it’s not like midnight-4AM in the morning and the rest of the truck park is asleep, some folks just don’t give a toss about others and it’s been said before on here by the now absent MR. K amongst others that if you can’t put up with other inconsiderate truck drivers being loud in truck stops then you shouldn’t be tramping which has some merit but I like to think i’m considerate so just can’t see why others can’t be, it costs nothing.
Some folks run the engine periodically to keep the battery’s charged so it’ll start in the morning which annoys me more to be honest as it’s usually 10 mins or god knows how long, foreigners are worst for this. If your battery’s can’t take an evening’s entertainment drain, they should be changed.
The fridge lads is another thread but at least they have to have the things on. Don’t know why more don’t have them on continuous rather than stop/start, as the it’s the start up that jars the night. Slow/low rev mode was always my friend when I was doing it.
Wrong occupation!!! What a pointless inane comment to make. I enjoy my job a lot, what I don’t like is inconsiderate drivers leaving engines ticking over. I’m certain I’m doing the correct occupation!
To the bloke who asked
And when a diesel engine is turned off the EGR valve goes to default position…which is open, thats if it is EGR, it might be SCR, and how does the introduction of already hot exhaust gasses into the intake manifold lower combustion temperatures. Its all eco bollox, very expensive and making my head hurt
The higher CO2 content of the recirculated exhaust gas added to the induction air slows combustion and hence reduces peak temperatures within the combustion chamber, and hence the output of NOX. Some engines incorporate an exhaust gas cooler too - works a bit like an intercooler, to combat the problem.
Or, you can take the NOx out downstream by adding AdBlue and passing the exhaust gas over a suitable catalyst.
Bet you wish you never asked!

Probably been posted before but why do people insist on leaving engines ticking over■■?Regardless of the time of day some people just can’t turn their engines off.
You know who you are!!! but could you explain WHY?? please
With a reason I could understand but I can’t find one - I know the turbo bit when you pull up but…10 minutes in a morning & the 5 minutes at night
Please explain
Oh dear?

not really. what’s the point of buying a house in the arctic, then complaining about the cold?
haulage by its nature is a noisy business.
there is an old saying, “if you don’t like the heat, get out of the kitchen”.
I get a daily bonus for driving performance based on telematics data from the unit i.e idling, revs, braking etc.
So I never idle, I even turn off at traffic lights if they’re slow.

do you know how much fuel is wasted when starting an engine?

Agreed a few seconds and just pull away gently and run it gently for a short while, the same as before you turn off, no need to idle it for ages to let the turbo spin down if you’ve come in gently as the turbo won’t be up to maxiumum anyway. Also getting it up to temperature while moving also get the gearbox oil warm which you won’t do idling it.
I’ve been told by many car engineers (and I don’t mean the fitter in your local dealer, but people who design and build engines) that excesive idling is bad for an engine. Something about the bores glazing.
However lots of cold stop start work isn’t good for them either, but this is really a problem for people who do short commutes in their cars where it never really gets upto temperature not your average goods vehicle.

Not as much as idling in traffic.
