A week ago I was staying over at one of my friend's house who really likes cars and enjoys talking about them with me. A few of the things that came up in our conversations were CVT's and Valvetrain Systems. First off we were wondering why the CVT hasn't completely replaced the Automatic Transmission yet. I had never heard anything bad about the CVT, only good things. The automatic to me seems so out of date and old when you could have a CVT. Manuals should still be kept around but who needs the automatic now?
Another thing is would it be possible to have a computer controlled valvetrain system in which a computer reads the RPMs of the engine and then depending on the RPMs it would open and close the valves to maximize power at that RPM. I mean they have things like drive-by-wire and steering angles that adjust to your speed and all kinds of other computer controlled things in cars so why not this? Would the computer not be able to process fast enough? I don't know enough about computers but i would've thought they could. I can see a major advantage from a system like this if it was possible. What do you think about this idea? And i was also wondering if anyone else has ever thought about this.
