> No engine in any car in the world has electrically actuated valves
It was just an example, I don't actually know what I'm talking about :) But it was my understanding that electronic fuel injection involves solenoids to, well, control fuel injection (as seen here https://en.wikipedia.org/wiki/Fuel_injection#EFI_gasoline_en... ).
The point is that conveying the operating principles should be the main goal, if you call that "theory" or "practical info", it doesn't matter -- if you don't understand the basics well the practical (or theoretical) details will escape you.
Your suggestion about getting rid of distributors sounds reasonable.
I'm pretty sure he meant that no car has electrically actuated intake and exhaust valves, which is mostly true, but the Fiat/Chrysler MultiAir (https://en.wikipedia.org/wiki/MultiAir) line of engines does have electro-hydraulic valve actuation which allows for variable duration and lift, and I think they don't even have a throttle plate.
