What the hell are you guys talking about?
Here (Belgium), nearly every gasoline engine runs on propane. It isn't harmfull for the engine. It is much cheaper then gasoline. It's cleaner for the environment. We get money from the state (700$) if we do the conversion. And use a safetyvalve to prevent blowing shit up. It can improve Performance with decent programming, but it is not much (2-5 hp), but it is actually less energetic then gasoline.
In Diesel engines it also does improve Performance. But so does adding gasoline with the diesel.
um, just some obvious obseravation & questions about your post:
1. you say nearly every GASOLINE engine runs on propane, and then you say propane is much cheaper than gasoline? i think i know what you meant to say, but the way you say it makes it sound like you use propane instead of gasoline, instead of propane being a supplement to the gasoline.
anyway, 50% of cars sold in europe run on diesel fuel (yay--good for the environment--whatever
) and the other 50% run on gasoline (how many are aided by propane i don't know)
2. how can propane be 'less energetic' but cause a Performance increase?
