No, this is not possible. First, the different pressure levels make it impossible to fill CNG into an LPG tank. Since LPG is operated with a pressure of 5 - 15 bar, the gas cylinder might even burst. However, the filler plugs at the refilling stations have different standard sizes. It is therefore practically impossible to fill CNG into an LPG vehicle.

Secondly, both gases have different ignition points and calorific values. The electronic devices, which are part of the conversion kit, guarantee an optimal combustion for a specific type of gas. However, if a different gas was used, the combustion might not happen properly, or might even be suspended.

However, I have noticed that many of the LPG and CNG equipment are shared except for a few items.

I have been investigating Teleflex's SGI. Apparently their LPG and CNG components are the same (injectors, ignition corrector....). The only thing different is that instead of a pressure reducer/regulator, they use a vaporizer. The ECU is for both fuels.

Chances are, when looking at companies that make Autogas LPG conversion equipment (usually European), they most likely use some components from the LPG equipment for the CNG versions.

Of course the tank is different. LPG is 10psi and CNG is 2000psi.

All the above LPG installation are illegal, any accidents claims will be null and void by the insurer.

These are illegal highway killing machines .

If you are knocked down by one of these vehicle, the insurer will disclaim outright as the fuel conversion is illegal, unless they can obtain approval from Puspakom.

Look at the way these LPG tanks being restrained in their boot by just two rubber harness. One sharp corner, these tanks will be dislocated and the hose will be damaged resulting in gas leak. Once the leaked gas in contact with the hot exhaust pipe, BOOM................BOOM !

I really hope PUSPAKOM can conduct regular road block to check on illegal LPG installations to clear up all these killing machines on the road.

i hope someone will raise this issue with the authorities as these cars are illegal killing machines .......

Maybe a rule can be made to open your boot to show the tank to the pump attendant before they allow you to pump.

Dear All,

It'll only be a problem that will endanger life and limbs, when someone who thinks he's smart; like the 'idiot' who calls himself 'YONG', starts to link the LPG cylinder to the CNG cylinder and then proceeds to top-up the CNG & LPG cylinders at a PSS.

That's when it's "BOOM-BOOM" time and hopefully nobody gets hurt or killed except for the idiot's pocket. NGV'ers only problem is how to identify this type of idiot without getting hurt or having to die in the process. I, too, have this phobia when I am lining up behind a private car at a PSS due to the reason as stated above.

I believe that there's still a lot of these idiots that just refuse to acknowledge the danger and at the same time probably mislead by their unlicensed & untrained LPG installers that it's completely safe i.e. restraining the cylinder(s) with rubber straps instead of using mild steel brackets and straps.

To these installers "it's everything 'OK'" as long as I can get the deal. How many people gets hurt or dies "it's not my problem".

However, if the installation is done to International Standards & Practices, then I think it should be 'OK', but I think at present the Standards applied is "ah tee, agar-agar chow hoh-lor" - meaning: I do have some knowledge, but not much or according to my personal Standards and not International S&P.

Regards,


tnlrandall

The sheer force of the two LPG tanks should be strong enough to paralyse

the passengers seated at the back of the vehicle during an emergency

braking.

The LPG advertisement should not be appeared in the MUDAH website.

It is posing a threat to the public security should any mishap occur.

It is absolutely insane to those illegal LPG installation in the vehicle.

This should be brought to the police attention of this illegal installation.

Should there be any mishap again, police are the one involved in the investigations. In my opinion, police should be the first one to know about this.

Trying to email to JPJ asking for the legality of LPG installation.

Emailed twice, but bounced.

Do you see any refueling valves in those LPG vehicles in mudah.com.my.

If there are, potential explosion is in the happening.

Guys, for the advert in mudah.com, the volvo car, i think you all had misunderstand here. From what i knew, there was a regulator design for LPG. The regulator was cheaper (last time) compared to CNG, but now not very sure since no demand on it. The only reason LPG regulator was not popular was the gas price always increased and not really economic. In terms of power, LPG was claimed better than petrol. I wondered the safety of the tank coz no proper testing on it for on the road conditions. But in terms of safety, if user only use LPG gas, "kaboom" issue was totally not relevent.

For the issue of "Can an LPG car be filled with CNG, or vice versa?", the answer was NO, TOTALLY CAN NOT SPECIALLY LPG TANK USE TO FILL CNG...

PLEASE, DO NOT TRY TO BE ANOTHER MCGUYVER AGAIN!!
