"Port fuel injected engines generally spray fuel early on the back of the hot intake valves before they open, which fully vaporizes the gasoline before it enters the cylinder."


Sorry that is incorrect, this hot intake valve at around 500 degrees helps vaporize some of the fuel, but cannot get it all. In theory it helps with a part vaporize which help start the burn sooner and faster that help vaporize more of the fuel within the chamber.

"Direct injection engines do not, of course, which I think (?) is why they produce soot. However, DI engines typically also get better fuel economy."


I know that does not really compute…all I can guess it they inject less fuel as part of the system.


"Gasoline vapor claims are unicorn material."


YET cars truly can only burn vapor.
