Could have sworn I remembered a video of a sedan, maybe in Russia, that had allegedly been converted to run on something like propane and the tanks were stored in the trunk. Sure this was more affordable than regular vehicle fuel, but when it got rear-ended… it exploded!
YouTube isn’t full of these videos by any means so maybe it’s safer than I thought?
it’s very common in turkey italy mexico and a couple other countries that sell lpg (propane-butane mix) at lower prices than gasoline, nothing explodes these tanks need to be certified (varies by country) and gasoline is already flammable so nbd
in a city where i live most of taxis are hybrids modified to run on lpg so it has to be both safe and durable
its a mix that varies by season because in winter higher pressure at the same temperature is needed, and in summer the opposite. and also in winter gasoline has a little butane dissolved, because it’s cheaper and has high octane number, and makes engine startup easier. its a bit complicated but it works
Are you familiar with the way California has winter and summer blends? I think it’s a slightly different principle, focused on being environmentally friendly in the summer when it shouldn’t be too hard for engines to start.
every country has these seasonal changes (except those near equator) both for gasoline diesel and lpg and this is before we get into renewable components
gasoline and lpg are changed for the same reason, it is to keep vapor pressure at the same temperature lower in summer and higher in winter. too low and it’s hard to start, too high and volatile components bubble out = gasoline degrades and makes smog in the city. diesel is more complicated because it gels out at lower temperatures but how exactly this happens depending on several things, and mitigations are different
We tried it pretty well back in the 1970s. It was not uncommon to see LP powered conversions on the road. People even experimented with wood gas systems. The problem with LP, at least where I lived, was those engines didn’t start well in cold weather. And the second issue was regulations required fueling stations to have someone(s) trained and dedicated to doing those refills. It was deemed not safe to let the common man, (you know morons), do that. That added to the cost. And finally, with an LP tank in your car, you could be driving around with a possible bomb or at least a BLVE under your ass. Which is not safe for those around you.
Sometimes to day you will still see LP powered delivery vans rolling down the road. So it hasn’t totally gone away.
if liquid lpg is injected, not gas then it can start on lpg only no problem. this kind of thing appeared later so maybe it was not available at that time, and there are cars that use lpg as only fuel. most of cars just carry extra container for lpg and leave gasoline tank as is, and it works as backup
it’s wild to me that americans don’t use propane as a car fuel
It’s wilder that we don’t use gasoline in our barbecue grills.
Hank, you use real charcoal or it’s off to jail with you!

Propane-butane, interesting!
Oh good

Ah!

We use bald eagle urine instead
