Re: Off topic:Bi-fuel

Hello.
CNG numebrs seem to be mixed randomly.
1.27,1.14,1.5 and 1.7 for the comparison with a liter of petrol. Sometimes 1kg of CNG is equivalent to 1,7l of petrol or 1,5l.
A m^3 is equivalent to 1,27 or 1,14. A kg is 1,14m^3 and so on. Somewhere it must be an error of course.
For LPG the stoich ratio is 15:1 approximately and 1,2l is equivalent to 1l of petrol, the power loss is little.
For CNG the power loss is bigger,I can't understand if the stoich ratio is 16:1 or 17:1 approximately and the fuel consumption.
I collected other numbers,I don't know if they are right,I hope so,many things are unknow for me.


Other numbers and charts.

I saw other numbers for petrol,LPG and CNG about the reason it takes more ignition advance when you run on gas.
In a previuos exemple the way to calculate the gas and petrol consumption ratio was different.
I took the scheme of conversion kit using a ditsributor,perhaps they are discontinued, I didn't know about them.
I used to think there were the Necam one only.
The VE is littler on gases. I'd like to learn how to do all those calculations.
It can be a good idea to try and increase the compression ratio.
Have you ever heard of Marini autogas? I think they have made conversion kit using a distributor too.

They make a device for closed loop that I can't understand what is.

I can't understand if the regulator for injection with the distributor is the same used for mixers.
Bye.
