Conversion to gas and petrol bi-fuel vehicle successful

[Genie47]

CNG is 130 octane. Higher octane number, harder to detonate or ignite. Even if the gas is fizzing out, you really need one hell of a flame to ignite.

 

Well unless there is a catastrophic tank failure, the tank just explodes from the pressure but no fire.

The reason why petrol tank do not explode when they are shot at, is because the tank is not pressurised. If they had used a tracer round, the tank would definitely explode cause the three element is there....air, fuel and spark !

 

Now, the CNG is a different case. If they shoot at a CNG tank, they would definitely need a Magnum round to be able to penetrate the thick reinforcement around the tank. Once it is pentrated, it would probably explode because of the very high pressure forcing it's way out of the cracked forced opening on the tank. Needless to say that if they used a tracer round and it is powerful enough to penetrate it ( GMPG round, 30mm AA tracer rounds etc ), the tank would definitely explode !

 

Just my 1cts "scientisfic" thoughts !

[Genie47]

Know of any police force or criminals in the world using tracer or incindiary rounds? I know HK police use hollow points but that is antipersonnel.

[Konspire]

yes, when they r shooting at night for moving target....

Can we convert a hybrid car, like the honda, to gas? That would be very cheap to run wouldn't it?

[Ac67]

I wonder did I miss a point here. 60L of gas provides travelling of up to 160-180km, which works out to 2-3km/l for gas. This also means I will need to top-up the gas very frequently as I travel easily 400km per week. Perhaps the regular gasoline tank is to be used as 'backup' fuel source? Imagine driving this travelling NSH.

i read once of taxi drivers complaining they had to top up in jurong island every few days compared to diesel.

 

and 2K still high for conversion. isn't there any competitors?

[Genie47]

The tank is 60L capacity. But in weight is 21kg. 1kg of compressed gas is roughly 1L of petrol equivalent.

 

So for example if take my car which consumes 7.6L/100km. Then with CNG it should be around 7.6kg/100km.

 

You don't count in L. If you want, you got to do math and convert the kg CNG to GGE which stands for gasoline gallon equivalent to petrol.

 

OK got better values. 1kg CNG = 1.25L petrol = 0.33 US gallon petrol.

It will be cheap but defeats the purpose of the hybrid. Remember, the petrol hybrid is designed to run on petrol. Its electronics are tuned to run on petrol.

[Genie47]

Let's compare with Honda Civic!

 

Why Honda Civic? Because it is the only manufacturer with a model that covers all the engine options.

 

See this link:

The Civic Hybrid is the champion because it burns less fuel but overall, the GX with its CNG tuned engine churns out less CO2.

Lastly before anyone converts, read this from Singapore Power.

I will have to examine the Civic GX's placement of cylinders to get a rough idea. It has tanks equivalent to 8GGE.

[Kelpie]

I will not be surprised that they are placed where the petrol tank is. Honda GX is not a Hybrid. So it will have room to hide the cylinders in a more organized manner.

The old Civic GX still has it in the boot. As a result half the boot space gone!

 

The new FD GX most likely has it underneath.

wow..if we hv to compromise the luggage space like this....quite bad if we used to frequent to MY. then how abt MPVs then...no space to give oso...

[Genie47]

Yep. MPV? No from the last I heard, most family of 4 or 5 owns MPV. Last row seats confirm not used.

 

Can use roof rack lah. Anyway, I have examined my boot space. I can sacrifice that amount because I don't use the space immediately after the seats. Ask me to reach inside is back breaking.

 

Now I am seeing if I can sacrifice my spare tire for additional one or two tanks ala MB E200 NGT.

i use ley...how? now my 5 seater car like MPV already, accomodating 7 ppl......btw, is that the largest we can have? 60 kg?
