Seemingly it doesn't work that way on gassers, even though maybe those new direct-injection engines could eventually resort to it in a way more similar to a Diesel engine, as it would enrich the AFR. However, even for direct-injection gassers, most of the setups I know rely on liquid-phase injection alone through the stock fuel rail as an alternate fuel, but never as a gasoline booster. CNG on the other hand, as it's only injected at the vapour phase, I have already seen vehicles fitted with direct injection for the stock fuel resorting to it and CNG through a dedicated port-injection, as the stock injectors must always have some fuel flow in order to prevent them to get damaged as they're directly exposed to the flame spread, even though the gasoline and/or ethanol (just to remind, flexfuel engines have been prevalent in my country) flow is trimmed down in order to replace more of it with CNG for economy purposes.
