LP/Diesel Hybrid Car?

Question

Is there such a thing or a prototype of a liquid propane, and diesel hybrid? The diesel would eliminate the safety concerns of gasoline. If you can't mix in the carb, why not seperate engines? Maybe LP in the front, diesel in the back.

Answer 1

Keep it simple and buy a car that runs on natural gas. They actually exist and have for years. I have 2 of them, both made by Ford several years ago. They burn cleaner and way cheaper than anything else out there, and there is plenty of natural gas here in the USA, so your money stays in our own economy. The downside is there aren't a lot of places to refuel in some states, and there aren't a lot of these cars around, anyway. Check out my sources below to learn more about it!

Answer 2

Volkswagen has been making a diesel/electric hybrid Rabbit for a while.

I don't think diesel/LP makes sense. Diesel requires compression high enough for ignition without a spark. All the natural gas/LP powered cars and vans I know of are gasoline conversions. They are common fleet cars.

Answer 3

"The diesel would eliminate the safety concerns of gasoline."

While propane adds whole new ones that are even worse.  There really isn't a safety concern with petrol provided you aren't fired on by incendiary ammunition but LPG does have the potential should there be a leak to cause an explosion (since it is heavier than air and a gas at normal pressure it'll pool around waiting for a spark) which is why it is important that LPG not be allowed to leak (or that if it does it comes out really fast so as to not have a chance to pool together).

Now LPG can be engineered to have decent safety but if you are concerned enough about safety to be looking for a diesel instead of petrol then LPG ain't for you.
