I love magic. From the gas tank to the intake ports with DI. The only explanation that comes to mind is that valve overlap allows some mixing, but I think it is insufficient. Does anyone understand variable valve timing well enough to know there is enough pass through to matter?
I think there is a reason car bakers are starting to add port injection to DI engines. GM is doing it now for their V8s, in part to reduce carbon on the backs of the valves and in part because port injection is better than DI during extremely low loads like engine idle.
