Very informative video 4 sure.
Yup direct injection is by no means perfect but that's one of the schemes the automakers have had to resort to in order to hit the government legislated/mandated clean air & CAFE standards.
I think Audi ran it on their diesel powered Le Mans prototypes that dominated that class for a few years.
But over the long haul direct injection eventually needs serviced like everything else. Just like CVT transmissions. LOL
Better valve stem seals & crankcase evacuation systems will help solve some of that.
Some of the new cars now have electric vacuum pumps on them for pan evacuation .
Step Away From The KOOL AID !
