Stobarts new volvos gas power

Tell you what how about you find the definitions of those 3 terms and post them here. :unamused:

The Oxford dictionary should help you with that.

Itā€™s been fun reading your err, various degrees of in-depth knowledge about gas powered diesel engines. My old mate was one of the first to do a lot of it and went all over the world converting them. Buses in Brazil, spent a bit of time at ā– ā– ā– ā– ā– ā– ā–  in the USA and did something on tanks in America but I never did find out too much about that. In those days it was very basic and all they had a series of jets that let the gas out, each one twice the size of the other. The smallest one was the size needed to allow it to tick-over, next was twice that and so forth. so your switching would be (as the revs increased from tick-over)
Jet 1
Jet 2
jet 2 + 1
Jet 3
Jet 3 + 1
Jet 3 + 2
Jet 3 + 1 + 2
Jet 4
Jet 4 + 1

etc, etc.
He fitted 8 jets, but never needed to use the 8th one, he had a major thing about 7 jets looking better and more professional that 7 ?!?
The results were quite good and they drove OK but it was all just lip service and just done to pacify the green movement that was equally as loud back then.
Oh, and they used 10% derv (normally) as a ignition source.

Detonation is a major issue on certain race bikes. So much so that they have a detonation counter that counts the knocks and gives you a bit of notice so you can make adjustments to either timing or swirl chamber capacity. Never needed that when we could get 5 star! Bloody crud modern fuel is.

But I haveā€™nt said anything much different to what wheelnut said but itā€™s Brentanna who seemed to want to make an issue about that in my case not his for some reason :question: .

Hi Carryfast,

You might not have noticed that youā€™ve been moving the goalposts and evading perfectly sensible questions for several pages, but others have. :wink:

IMHO, youā€™ve posted nonsense, irrelevance and obfuscation (in varying ratios) at Olympic standard and in biblical proportions.
Scarily, some of it is even at weapons grade. :open_mouth:

If thatā€™s true thereā€™s only one way to find out and thatā€™s to arrange that test with a fully freighted 44 tonner running with 95% LPG ignited by 5% diesel.But sadly the Antar powered by the Meteor instead running on just LPG will have to wait.

more than 95% LPG ignited by 5% diesel

Thatā€™s the secret :wink: . You have cylinders bigger than 100% (more than 95 = 96min + 5 = 101%) which totally alters the laws of physics :laughing: :laughing: :laughing: :laughing:

did he finally get it ?

If detonation is a major issue on naturally aspirated race bikes with the revs they run at what do think would happen in a turbo charged diesel truck engine using LPG :question: .But you can still get race fuel which has as much octane rating as 5 star had and LPG is around the same or a bit more and were those certain race bikes which you were referring to comparable with that one which you were saying has 15+:1 CR :question: .

But are you saying that your mate was converting turbo diesel trucks,buses and tanks to run on 90% LPG with a 10% diesel pilot :question: .If itā€™s possible then what are they waiting for and why the zb is everyone paying for diesel instead when they can fill up with LPG almost anywhere :question: .

Glad you noticed the mistake.That would change everything. :wink: :laughing: :laughing: I said that Brentanna should be working on the Starship Enterprise but it looks like Iā€™ve beaten her to the job instead. :laughing: :laughing:

Brentanna:

Iā€™m still waiting to hear from wheelnut to see what he thinks.If heā€™s changed his mind then Iā€™ll give up :question:. :laughing:

Iā€™m still waiting to hear from wheelnut to see what he thinks.If heā€™s changed his mind then Iā€™ll give up .

But you were not in agreement

If wheelnut isā€™nt in agreement with me,about the unviability of running a turbo diesel truck engine on 95% LPG with a 5% diesel pilot,then let him say it for himself.But as I remeber it he said that youā€™ll ā€˜probably knock the bottom end outā€™ even if you could provide it with the spark/ignition source :question: .

Wheel Nut:
This company has been involved with gas trucks for some time, and supplies many of the fuel stops in the UK and are often seen abroad.

chive-ltd.co.uk/chivefuels/a ā€¦ efuels.htm

The lads who ran the Vauxhall trailers out of Purfleet to Ellesmere Port and Luton were on gas too. Hardstaffs have a mention on Chives website!

This company supply lng not lpg as the 2 get mixed up the stobart trucks run on lng liquified natural gas or can run on liquid biomethane from waste great idea according to volvo trucks website they are doing trials in the uk ie stobarts and in sweden and are looking to bring production line duel fuel gas trucks to the market this year but where do u get the gas from?

A diesel will not run on LPG without a spark and you would probably knock the bottom end out even if you could fit plugs.

:wink: :smiley:

^ Just in case anyone missed it the first time.

:unamused:

so we are to ignore the part where he says even if you could fit plugs. Thats a conversion not using it in its existing form.

Brentanna:

If itā€™s fitted with plugs then whatā€™s the difference between that and using a diesel pilot ignition source instead :question: .If everything else remains as it was then youā€™d be using the engine in itā€™s ā€˜existing formā€™ in just the same way regardless of which of the two methods used to ignite the LPG.Except with plugs you wouldā€™nt be wasting money on using expensive diesel to light the stuff.Unlike your idea.

Wheelnut seems to have gone very quiet all of a sudden. :open_mouth: :question: :laughing:

Yes Carryfast. he was and we are going back 20+ yrs ago. They did the buses in Brazil to run on methane from the massive waste dumps near the towns, a free fuel. Not sure which gas the others were on but I can find out as the bloke who did a lot of the work with him calls in quite often. Not sure why you find it surprising, there are plenty running on gas now and although itā€™s a cheaper fuel at present, as numbers increase to revenue from normal fuels will decrease soā€¦well, sure you can work the next move out.
By the way, the derv you use to ignite the gas is not wasted, it still adds to the combustion force, itā€™s just only a percentage of that force, the rest is the cheaper stuff, the gas, which will soon be as dear when enough are using it.
The jet method of doing it was fairly crude by todays perfect common rail, millisecond opening injectors standards, but was adequate in itā€™s day and the 14 lt ā– ā– ā– ā– ā– ā– ā–  worked very well on it. I know at the time you were not allowed to compress natural gas to run vehicles in the UK.
re the race bikes, the detonation problems are most acute on 2 strokes, thatā€™s why you have head inserts to adjust the squish. A few ccā€™s less metal if the det counter goes mad. The new fuels may have all the additives and all the rest, but itā€™s nowhere near as stable as when we had the good old lead in it. Temp rise, humidity etc used to work on a fairly regular sliding scale in them days but now you can do a practice and qualifying on Saturday and all is OK, then come race day it hardly seems to alter atmospherically, yet the motor goes mad. The 4 stroke multis donā€™t give too much problem with detonation (if any, itā€™s usually a sign the head gasket is slightly weeping, or on a Ducati, the heads gone porous) as we donā€™t run much over 15:1 as itā€™s generally regarded as being into the realms where the compression works against you lower in the rev range, but I believe the older singles in classic have a few issues and certainly the old classic motoX bikes.

I bow to curryfarts superior knowledge of the entire worldā€¦ I have to say that he must be the most intelligent man on the face of the planet. Einstein pales by comparisonā€¦

Now then, as you are so ā– ā– ā– ā– ā– ā– ā–  clever, curryfary, tell me how the carburetter engine works on LPGā€¦ Furthermore, please tell me the compund differences between Liquified Petroleum Gas and gaseous LPGā€¦ I want to know your take on itā€¦

You, as the fount of all knowledge on everything must be able to tell this dumbass truck driver, who lives in an igloo in the middle of the barren wasteland which is Canada because I need to know.

While you are at it, can you please advise me on how best to deal with icy conditions (-30 tonight) and how I should act with regard to the unionsā€¦ Also, my wife has had a heart attack and is suffering from heart failure and kidney failure, so could you please get over here as soon as possible and fix her up?

Either that or, for the love of God, SHUT THE ā– ā– ā– ā–  UP!!!

May I ask what make and model of car you drive?
There is a genuine reason for this as I will gladly explain when I have the answer.

Posted that on other topics.But the relevant bit is that I donā€™t drive any diesel cars running on LPG because they couldā€™nt anyway although ā€˜ifā€™ I ā€˜hadā€™ a diesel car, which ā€˜couldā€™ run on LPG instead,then Iā€™d certainly be running it on LPG not diesel just like I would if I was running a truck. :bulb:

But Iā€™m still waiting to find out what wheelnut thinks considering that I haveā€™nt said anything different to what heā€™s said except that I got a load of stick on here for saying it whereas he didā€™nt. :unamused:

Wheelnut was on earlie he is just ignoring your stupidity, as he has already stated, and you argued with; he and yourself are not in agreement.
