If the vehicle manufacturers were to eliminate the camshaft and control the valves by computers instead do you think it would benefit the vehicle if so how If not why?
benefits would be more precise running of your vehicle, you
could alter the performance in car, very easily, you wouldn't be
limited to your power range as a camshaft is very limited, &
only opens valves as much as they are set to.
electronic, or air lifters, or what ever style you would suggest
can be as variable as you want them to be.
however, it would be expensive, & less reliable, there would
be greater chance of failure, but with modern technology coming
along, its likely to become more & more reliable, maybe one day
we will see this on top end cars off the shelf.
