Hmm.. this seems intersting. Heating fuel enough to vaporize it before injection.

already invented, wiki "direct injection", it isn't heat that vaporizes the fuel, its pressure.

Not in this application. The article says excess heat from the radiator and exhaust manifold are used to vaporzie the fule in this system.
