The majority of this thread is way over my head, but assuming the 3.9L engine has no boost at idle, then by my clacs it would be consuming 1365L of air /minute (3.9L / 2 stroke x 700rpm). It also ignores volumetric efficiency issues at this rpm, but I'd say it would be negligible anyway. Either way...

KiwiBacon

It doesn't matter what you did Bacon. Its wasn't a true scientific experiment, especially as the whole experiment hinged on correctly and acuratly measureing gas flow. As a result, the inacuracy this critical element of the experiment made the results inadmissable to this arguement. VVega has corre...

oh so your throwing your toys now and resulting to personal insults our test was done using calibrated gear .. end of the day your test was wrong its proven .. get over it sorry typo 60 odd not 6 :D your opinion means nothign kiwi your just a sore little man and it shows .. must be gutting :D So yo...

lol its funny because hes got fume working and you havent ... so really ill take his word over yours anyday basically i dont see how you can call anything i mark the people i listen to on success ... hes has it ... and you ... dont and again your calulations are wrong for the bucket lp gas compress...

Wopass deserves some credit for the title of this thread.

arh well i guess you will just keep goign and keep going and going and going 4.5 liters of lpg is to much ive talked to a desil man today ... a veyr clever one .. he seams to think that at idle because of the crap v.e you engine would barly use 6 liters of air a min to your 4.5liters of lpg ...with...

TD42 no turbo. will push the hose onto the air intakes breather pipe thing so that it feeds into the intake and put a coke bottle with a sock inside it over the breather hose to collect the mist. Wont need a gas flow-meter? I'll just open the tap slowly while the motors under load untill it starts ...

I'm going to do this tomorrow after work. Will pull a homer to make the required brackets etc. I want to mount it on the center console between the front seats so that i can reach the tap to turn it on and off/make fuel adjustments on the fly. Hopefully it wont cost me anything! scrap steel from wo...

KiwiBacon

you were pumping in 4.5ltrs per min? at idle??? thats too much gas!!! too much gas!!! too much gas!!! read the posts from the people that actually run fume properly and read the usage...then work out how much you are over doing it by...remembering that it doesnt fume at idle...at all...ever... for ...

KiwiBacon

well no i dont know if your calculations are correct and at the moment .. i doubt that they are please dont try to bend my comments into somthing that serves your purpose when you planly dont even understand the context there writen in It's not that hard to check the calcs. All of the working is sh...

youve missed the point yet again your igniting the petrol .. not the vapour to put it in the same context take a container of fuel vapour let it go in you lounge ... do you think if you heat the room enough it will auto ignite ?? its so simple yet you just wont grasp it ive tryed to help you ive pr...

vvega is saying auto-ignition is impossible if you're below the lower flammability limit (i.e. too lean). The experiment I ran clearly shows it's possible and happening.

KiwiBacon

Hang on.. so if you put fuel in a fire.. and the fuel burns.. the process is called autoignition? even though there is a flame involved? No, you need to heat until it lights without letting it touch a flame or spark. That is auto-ignition. If the flame gets it, then it's just normal flammable combu...

KiwiBacon

Here an explanation that'll be right up vvegas alley. Tuning a petrol. Flood it with fuel (go past the upper flammable limit) and your spark can't ignite it. Run it too lean (below the lower flammable limit) and your spark can't ignite it. But take a can full of that lean petrol/air mix which is inf...

KiwiBacon

you have to have a ignitable mixure to have a autoignition This is not true. Flammable and capable of auto-ignition are not the same thing. How the hell could something Auto-Ignite if it was not ignitable -nathan Ignitable means stick a spark through it and it'll go up. If something is outside the ...

KiwiBacon

you have to have a ignitable mixure to have a autoignition if its below the lower flashpoints limit then its not ignitable This is not true. Flammable and capable of auto-ignition are not the same thing. Do you have any references to back up this concept? How does the observed detonation at concent...

http://www.overlander.com.au/equipment/index.php?id=89 Just had a chance to read through that. This one was interesting: LPG fumigation in diesel engines uses a concentration of about one-half of one percent.

Pot kettle black... I've read my way through this thread and the way you present yourself leaves a lot to be desired, hence the reputation you have which seems is already widespread? Since the subject of the 970nm 4.2 6cyl diesel has popped back up - does tyre size have an effective on torque measu...

im sorry mate but you dont even understand a flashpoint i dont see how i coudl have any confidance that you know what your talking about and really is probably the issue with your lack of achevement you simply dont have the understanding of what your tring to do Okay, lets go back to flashpoint.

KiwiBacon

kiwi as a man of engineering you muct understand that there are fixed rules than cant be broken one of those is that autoignition cannot happen at below the lower limit i mean seriously.. it cant happen You don't understand what autoignition is. It's the gas itself being heated until it self-combus...

My 2c worth, May not be worth even that much,, But .. 1.5% lpg to air volume is waaaay to much , Isnt it 1.5% of Fuel volume ? My kit takes About 100 ltrs of Diesel to use a 9 kg bottle of lpg . I havnt got a degree in maths , so can one of you work that theory out ? 100 litres of diesel is about 8...

I dont see how you can compare a properly designed and controlled system with prior R&D with a 5 minute 'shove a hose up the intake' experiment. You already seemed like a dick, but to try and do something like that and then to go on defending yourself and asking people to admit defeat (like it'...

KiwiBacon

OMG, you claim this to be a scientific experiment??? Spose you fella's are only engineers :lol: :lol: (dig dig dig at vvega :wink: ) Your method is incorrect, especially as you are trying to prove a preconcieved hypothysis. Nope. It's measuring the fumigation rate necessary to provide audible deton...
