No, fuel will only burn once it has vaporized. It may land on the surface of the piston and walls but it vaporizes before it can burn. If there is any liquid fuel left when the flame ignites, the liquid fuel evaporates before it starts to burn.
The point of any kind of fuel injection (whether electronic or plain old carburetors) is to first meter in the exactly right amount of fuel, and second to vaporize it completely. I'm guessing that statement from the manual was just incorrect, or was talking about something else. |
