Vapour Injected LPG

I think trying to inject liquid would be interesting. particularly 
with direct injection.  The problem I have been told is that butane, 
propane are fantastic refrigerants (except they burn) and freeze 
everything around when they change state.  Hence the big ole water 
heated vaporizers.  Maybe somebody makes some cryogenic injectors.
