Refuelling with car running

Dieso doesn't just require compression and heat. As it is a combustible fuel (not flamable), it will also ignite if supported by a wick, ie rag

I tend to agree with most of what you are on about

BUT
Spray diesel and that's a different "kettle of fish".

Think of boilers, not the Mrs variety, but the steam generator type, !
Bugger all compression there.

Dion and Bucky,

You are both correct in what you say, but in the two cases asked about I see no danger of ignition happening.

"Number one question is, is it ok to run a Waeco under a tonneau with 2 full jerry cans of Diesel?" Providing the jerry cans are closed or there are no diesel soaked rags - that are already burning - under the cover no source of ignition.

"Number Two question is, is it ok to refuel the vehicle with jerry cans while engine is still running?" Unless you spray the diesel into a mist and provide a source of ignition - Heating diesel to above 200degC (I think) will start ignition but the diesel must be kept at that temperature - it will not ignite. But I think you would have trouble misting the diesel when pouring from a jerry can.

Like I said I would have no worrys about doing either.
But what I think is safe and what someone else thinks is safe could be two different things!

Have I just added fuel to the fire?! ;-)

Regards,
Kelvo

hi the boss
i'm ok with both providing the containers have a good seal

i would be more concerned about how the wanko fridge is going to survive under a hot black tonnea cover in the sun
imho i think it would be struggling
as a farmer from the past i could'nt count the number of times i refueled vehicles and machines ----- except for auxillary motors ------ while they where still running without any drama
cheers

I'm with Gramps. We have only done it once. Christmas eve when our alternator packed it in. We had to get to our destination to fit the new one and didn't have enough fuel to get there. Jump start with a caravan in a busy petrol station on Christmas eve was not going to happen.

"I'm with Gramps ....... "

Careful Old Girl , that could lose you a lot of friends LOL

Regards

Righty O, I agree with then.
Funny bugger.

Hahahaha sometimes it gets a bit too serious around here.

Regards

Yeah ya right, but will be covering 1500kms that day, so will be pushing it for time. Will only need to do this once, but there will be smokers travelling with me so might aswell just wait while they have there smoke and then refill.

Problem solved, cheers

The other point to be made is this weird pre-conception that a turbo MUST be cooled down before shutting a motor down.

If you were to fit a EGT gauge (instead of a stupid turbo timer), you would very quickly realise that there are very few occasions when you would normally be tempted to switch an engine off at a time when the turbo would need to be cooled down beforehand.

Assume you have been running along the highway at 100k/h and decide you're going to pull up for smoko or to refuel etc. The EGT would possibly be about 400oC going along (unless you've been slogging up a long hill etc). By the time you back her off and slow down to a stop, the EGTs will have reduced to about 250oC. This is a safe temp at which to shut the turbo down without damage.

If however, you HAVE just slooged up a big hill and have to pull over at the top (or half way up) and the EGTs are hitting 550 to 600oC, then you would probably want to let her idle for a couple of minutes before switching off.

I had a turbo timer on my first diesel (a 1993 RX Patrol with Safari Turbo). I got "chipped" by a copper once in Cooma because I shut her off, took the key out and walked into the shops with it still running (2 or 3 minute timer set). He informed me I could be booked for leaving a vehicle running and not being behind the wheel. I still used to do it on plenty of occasions, but with my next Patrol I did some research and found that all those years I'd been letting the turbo cool down, it wasn't anywhere near hot enough to have bothered anyway..... hahahaha

We live and learn i guess. Turbo timers are a complete waste of time IMHO (provided you are an "aware" type of driver who has a mechanical "feel" for his rig).

Roachie

Have to agree and disagree at the same time Roachie.

A diesel fitter mate of mine swears by them, Its not just about the temp of the turbo, its about allowing it the correct amount of time to lubricate the bearings to prevent tarnishing. It wont happen overnight, but it will happen.

I agree though that it doesnt require it at all times, but when its been running for hours on end, i would rather take the precaution. I will definitely be looking into getting an EGT gauge fitted though.

I'm with Roachie.
Modern turbo's with modern bearing material and todays synthetic oils all mean turbo timers are a waste of time.

If they were required then the car would come fitted with one from new by the manufacturer with instructions to use it.

By the time you have slowed down to stop the EGT has dropped sufficiently to be a non issue.

Well in my manual it says to idle car after heavy use or driving at highway speeds. Thats a good enough reason for me.

Why do you have an EGt gauge, If they were required then the car would come fitted with one from new by the manufacturer with instructions to use it.

Hyundai Getz dont even have a temp gauge anymore, does that mean there not required?

I take my advice from people in the game, those who have the knowledge and experience, and those build the motors and those that have to rebuild the motors.

If it was a problem then you could realistically expect to see dozens if not hundreds of turbo charged engines dropping their respective guts all over the country.
It simply does not happen other wise I have no doubt it would be well written up on this site.

The other argument is that it will extend the life of the turbo/engine??
With most modern diesels pretty well good for about 500,000 km's it begs the question of how much more or less difference than this will it make??

I don't have an EGT in my vehicles and given that I can says its fairly improbable that I would come to a sudden stop after driving at high speed for long periods and then immediately turn off my engine it would be quite reasonable to assume that the few minutes of slowing down as you would do say coming into a town or city is sufficient to drop the EGT without issues.

I have both a turbo diesel and a turbo petrol (XR6 Turbo) and neither manual makes any comment about idle down periods.

But if you want a turbo timer then thats fine after all its your money.

Cheers

Prob think that you are about to do a runner :-))

Oh right, when i worked at a fuel deopt, i used to test diesel coming off the ships and we flash tested it at 85 degrees. If it flashed it was sent back?

The Boss

Thank's for the info, you are probably correct, I'll take practical experience over text-book information any day.

Cheers Snowy

How are you going to do 1500 Kays in 5 hours?

And police wonder why the road toll is up?

300 kkk'sss an hour, thats for the one, Tukka, his mate below says he'll do it in 4nhalf with one hour rest

Yeah us young fellas ay, do everything at a thousand miles an hour.

Pity Tukka's eyes cant see 30 feet in front of him. He has a hard time scratching his own nose.

Its a pity the new BT50 cant do anything over 110 kph...

300 kph in the old tray back is understandable

Its the same creepy gay laugh i do when im creeping around your yard at night time pinching stuff off your half breed new 4x4....

Should be a good trip to perth for the concert, havent been down that part of wa for along time in the car, should be a little different.

Hey Doug, when im on the road i just like to drive, i hate pulling over unless its for fuel or to swap drivers/check over car. I like to do a big day the first day and then the next day is only a short drive, so no peak hour traffic in the big smoke.

Funny you say that about heart attacks mate, i'm in the process of trying to solve some medical dramas. 4 ECGs, Echocardiograph, 6 blood tests, X rays, $2,000 in medical fees, take 2 tablets everyday for remainder of life, and they still cant find the problem. Back tomorrow for more tests. Probably throttle the doc if he gives me the same old story.

Cheers Pop. I agree im not in that much of a hurry.

But as for the Diesel, i worked with the stuff for 4 years in a Coastal Bulk Storage facility. We used to smoke while we bolted hoses together for discharging ships and such, and we all used the ol saying, ''ah, its only diesel''.

Until, the day we had to do a special fire training course. Let me tell you, we learnt a thing or two about diesel that day. Around 30 times we dropped a match into a bucket of diesel, and 30 times it lit up. We trialled petrol and diesel and the diesel was hotter, smokier, and harder to put out.

Still nowhere near as volatile as petrol though, but christ it was still easy to ignite.
