My question is in regards to the direct injection system on this engine. Nissan refers to the system as DIG "direct injected gasoline". I know this version of the VQ35 came out around 2017 and is found in all Pathfinders and Muranos for 2017+, plus I believe some VQ35 powered Nissan cars.
What I haven't been able to determine is if this engine has a means to inject fuel upstream of the intake valves like some have been designed to do to keep the intake valves clean(er). Both DI and port injected of sorts.
I've poked around the engine bay of my 2019 Pathfinder with the VQ35DD and I can see the hard piping for high pressure fuel getting routed under the plastic upper intake, but I can't see any low pressure port injection.
Little/no info online on this engine that I could find. Figured here would be the best bet.
