E-camshaft
hey everyone,
im in high school, and yesterday in my physical world class, i was bored, and i got to thinking about what a cam is, what it does, how it works, and i got to thinking, there are a lot of moving parts in the whole set up of of the cam, that means there is a lot of room for something going wrong, friction, heat, drag, less horsepower..... i turned to my friend who sits behind me ( he is also really into cars ) and i ask him if there is such a thing as a electric cam. right now, they are mechanical ( analog ) lots of moving parts, i was wondering if there is such a thing has a digital ( no moving parts ) cam shaft. at first he looked like he wanted to slap me for being so dumb. so i turned around, and continued to work. then he tapped my back, after he thought about it for a little while, he liked where i was going with this. we got to talking and " inventing " ( all in the middel of a lecture
). what do you think. they got rid of the distributor, i think its possible to get rid of the cam. give me some input, positive, negative, comments, or oppinions.... thanks.

RE: E-camshaft
In my personnel experience I have seen maybe a hand full of cams out of hundreds that have went bad, the camshaft almost always goes bad do to improper installation or part matching. As far as the heat,friction and loss of power they made roller parts some time back to help deal with those problems not to mention lubricants are getting better. Nothings impossible, I dont know if such a thing exists though. Replacing the distributor was less complicated than it would be to replace the cam.

RE: E-camshaft
ford 6.0 diesel is a camless motor and a company has made a new digital cam motor, how ever it is very impractical still they probly wont be put into use for quite some time, i have it in a book some where if i can find it ill post more info. if i remember right the valve are being opend with actuators i want to say hydraulic but im not 100% sure but theres many more moving parts it is quite a bit larger and heavier then a normal cam motor at the time being. the concept came about from variable valve timing (most common is V-tec)
ok i found an article on a CLE motor its not the same one im thinking about but here u go...theres a few more search CLE or camless engine/motor on google

RE: E-camshaft
there was something some time ago about rotary cams, which reduce the overall amount of moving parts etc etc in the vehicle, pretty good imo
As for a digishaft or something like that, simultaniously controling intake and exhaust in coherence with crankshaft timing, individual timing and ignition spark offers unlimited tuning posibilities, easily programable by parameters and tables throughout an almost endless rpm range (right? if you extinguished the use of pushrods/chains all the way down to springs if you wanted, it eliminate valvetrain problems) it be amazing...this is the type of stuff I'm in college for
...the only problem would be creating a electric actuator for the valves that could survive 1000s upon millions of cyles and activations (thats the engineering marvel, not the computer program to run the digishaft, which is 90% done already in your car)
good idea, pay attention in class about it though
