CNG - Why it should'nt be in your car!

[FLi_GTi]

In all the commotion people saying that "stop-valves" prevent fire from reaching the Tank. In the second accident, note the filler neck is in the Engine bay and the explosion at the back.

Like i said. Do compare the force of the Blasts. I'm not talking about the deadly eventuality. I'm just discussing the force of the blow.

FLi, you're scaring people here just because you don't like CNG vehicles. I don't believe you. The CNG cylinder is intact in all pics, it didn't explode in any of these accidents. The cause of accident must be something else.

Not only in Pakistan, millions of vehicles around the world run on CNG. In New Delhi, all buses run on CNG, for example.

Benefits of CNG:

1. Low running cost
2. Environment friendly - no pollution
3. Lower pickup which means lower accident rate
4. Safe (yes, it is much safer than petrol)

as i would like to say again, jaan hai toh jahaan hai. Try to cut expenses to afford petrol, quit smoking, this that, you know there are many alternative methods through which you can get petrol, but people prefer the easy way out. any ways, Adeel bhai, thanks for enlightening us on the risks associated with CNG use, i for once was only considering the ricks associated to the engine, and how miserable it makes ones experience owning a car. So once again people, if you love your family, would like to live, please remove that ticking time bomb in the trunk of your car. A friendly message from your favourite ANTI CNG group. take care, live long and prosper :). I hope we all can learn a valuable lesson.

it was intended to be a joke bhai sahab
dont stand down and keep on sharing valuable information, please

waise i know of another thing apart from CNG cylinder which can give u a full blast
pata wee kharke taay.........

[SER_GTR]

hello!
1st of all...respect Adeel bhai.....magar yaar Adeel bhai...
Kyon Dara Rahe ho..........mere to abhi umer he kya hai :p.......
b/w....yaar i myself seen worst accidents in karachi....one is the dumper fully loaded falls on Suzuki mehran....car was still near my house......its all like some one hitted a big hammer on it....and i see CNG cyl safely placed there.......
so i think there must be some reason behind these huge explosions we can see overe there in pics...either gas is leaked somewhere from line and caught fire and then exploded cyl.......other things is that there must be some low quality made cyl they are using......here in karachi.....i think now 70-80% of cars are on CNG running daily.....no such incident i hear........
As for kind info....just a 55kg Fabre Cyl cost 35K buddy....so thats some reason behind that they are making 45kgs weight of Shiity Cyl Weight just to store 8-9kgs of Gas........so i agree that CNG needs lots of Pre-cautions.......best quality piping and heavy duty Cyl to bear that pressure...
as here its stored hardly b/w 200-250psi range...Pressure is the main prob here......so i think its not a Bomb type Scenario.......its a Safe Cyl...as Govt of Pak some days back offers list of Certified companies which offers CNG kits and CYl........so using best quality product is always benificial......
May ALLAH bless us all..........
Drive Safe......Use CNG with Care :).....
its Lighter than Air and Self-Igniting temp is twice of petrol.........so don't worry......:)...just be sure your CYl is good enough ..
Plz yaar ab koi na Darana.............
Thanxxx

FLi, you're scaring people here just because you don't like CNG vehicles. I don't believe you.

You seem like an observant person Pisces. How about you enlighten us how it happened.

I presumed;
The Gas Bowsers are intact so they did'nt blow (All three)
There's no other damage (fire or otherwise) near the vehicles so its not sabotage. (All three).
The Bodwork is blown outward in all three cases so I presume as anyone with half a brain would deduce what the direction of the blast was.
The Car's are not in a hostile environment so its not terrorism.
Gas boffins say that CNG is lighter than air hence it dissapates. Given that it was accumalating in the trunk/hatch watever the only logical reason for a spark is static! Screw me sideways if i ever had to worry about wearing rayon in gasoline vehicle.
Furthermore, I'm not here to make a believer out of you. Please feel free to assume/believe what you please, just refrain from making stupid, grossly misinformed statements like you did.

[Cylestyne]

Lets not assume this isn't a cng problem. It obviously is. I am sure you karachites also remember the phase 7 incident when the shell petrol pump was BLOWN TO BITS when the cng cylinder leaked (back in 2004).

CNG should be avoided! If we can't afford to keep cars like Citys, Corollas, Civics on petrol then we should buy something that we can afford on petrol. Plain and simple!

True CNG is dangerous, but its way too economical. I know of 2 accidents due to faulty cylinders. One in a FX and another one was in a Mehran.

Precautions:

1. Always get a Proper tested Cylinder. It has a satmp on it with the date when it was tested.

2. There is this Govt Authority which checks cylinders periodically. I cant remember there name at the moment but you can inquire about thme from any CNG Filling station.

3. Always insist on a seamless cylinder. The cases I mentioned above both had Cylindrs with seams.

4. Some good brands :
   *Faber ( Italy )
   *Inflex ( Italy )
   *EKC ( UAE )

HDIP hydrocarbon development institute of pakistan regulates these affairs
every 5 years, cylinder has to be approved by them otherwise its illegal on part of cng station to fill gas in such cylinder.
above mentioned brands are approved by HDIP

Lala, in how many instances have you seen a servo attendant checking for certification?

Please refer to the link above... alot of ppl said no such thing happened in Pakistan... the article above is somewhat the initial one... later investigations stated that there was some blockage in the Gas Pipes causing the explosion... now those blockages occur due to the impurities in the gas... imagine the same gas going in ur car & blocking the pispes... can cause similar damage... I have seen that explosion infront of me... I am scared of CNG myself...

Peace.

No Hard Feelings to Anyone

[spectra]

thats true
its enacted law with minimun enforcement, much like many other laws

[AsadIshaque]

Well I for one will stay miles away from a CNG vehicle if I can possibly.

My father is deadly against having any sort of compressed gas in the car, be it CNG or LPG. None of our cars including my trio of VW Beetles run on anything other than good old petrol.

And whenever I complain about rising gas prices, my sweet pops just raises my petrol allowance!!! Now dont you wish everyone had a father like that??

Regards.

[FLi_GTi]

Now dont you wish everyone had a father like that??

Here Here and Amen to that!

@Fli_Gti

You are right again....service station attendants dont check for the cylinder checking date but the responsility lies with us...The CNG Users...if we want saftey for ourselves and others.

[FLi_GTi]

True Adil. But then again, how many of these CNG supporters claim to use CNG for any of its other benefits other than the cost. AAJ petrol sasta ho dekho kabariyon ki kaisay eid hotee hai!. Soon the prices of CNG will be right up there with the rest. Then what? Like mods, there's no measure of how thrifty one can be....sometimes beglecting their saftey. Cylinders have been popping left right and center since the FON-GAS days,and now all of sudden there's justification?
I'm just not comfortable driving around with a can of compressed inflammable gas up my arse! I have a very thirsty car, when i can't afford the petrol, i "bus" it. No shame in that. Wanna help clean up the environment, USE MASS TRANSIT..NOT LAME EXCUSES. Cng is more dangerous than FF gasoline vehicle. EVEN if there's no gas in the cylinder, thats a 55Kilo projectil waiting to get loose and complicate matters in a high speed crash!!!
