electric valvetrain?

I think variable lift is out if its directly attached to a valve. and reliability? Big rigs run these injectors for hundreds of thousands of miles. Wiring under a hot valve cover is totally acceptable. We have transmission servos running under ATF fluid, knock sensors under oil too. I think the trick is to get a very low mass valve. Probably not directly actuated by this injector but by pneumatics. F1 had something like pneumatic valves in some motor, maybe experimental. @eeka440 Yes...just like that (hadnt seen that before!) . But not $40,000 for the head. Maybe for engineering day at school.
