I'm not sure of the exact reason(s) for putting them there but from observation out of the window I would say they produce a substantial vortex over the part of the wing above the cowling.
On the 777 the area above the engine doesn't have any LE devices, so the plate (vortex generator?) may compensate for this?
On rotation you can often see a wide fog trail extending from the plate over the wing...
