Yes, it can be confusing, but you seem to be a bit confused with well established technical terms and methods. In a previous post you wrote about an "Otto" engine in comparison with a diesel engine. "Otto" is the term used for a 4 stroke, or 4 cycle engine, named after its German inventor. It does not differentiate between a spark ignition engine (petrol. gasoline, kerosene, whatever), and a "diesel" or compression ignition engine.thaiger wrote:Even the abbreviations are confusing, LPG, NGV, CNG, LNG... seems like the easiest way to remember is NG for natural gas (or PG for petroleum gas) and then put either an L for "liquefied" or a C for "compressed" in front of it - if petroleum gas and natural gas is the same...Now what's a Polish system compared to an Italian system? Doesn't sound too confidence-inspiring either way...
I still don't know if a Diesel runs on NG since it's burning oil and not gasoline. Then there's the question if it's worth the investment for the conversion if the NG prices go up - you get a lot of Diesel for 30000 THB! If they triple like the gas/diesel prices, I'd be stuck with less space, less fuel stations and less fuel range.
The conversions being done here in Thailand, at least on smaller engines, use an electronic controlled (ECU), along with a bunch of other equipment, to MIX LPG or CNG with the diesel fuel, and the ignition is still on the high compression "diesel" principle, as far as I am aware.
Petroleum Gas, LPG, is as stated previously, is a by-product of the crude oil refining process.
Natural Gas is just that. ie: gas that is extracted from the ground in its natural form. To be of any use to us it has to be compressed, both for storage and transport, but also to confine enough energy in a usable form.
They are entirely different forms of energy.
Do not be put off by Italian gas equipment, they are considered to be leaders in the development of automotive gas equipment. The Polish equipment has its place, and like everything else, you get what you pay for.
