I have the following question in my mind but not sure if it could be worked out...

1. Let's say I have a V6 engine.
2. Can I have the camshaft in pieces that can be connected to form a normal camshaft when the engine is running?
3. The basic idea here is to have only one cylinder working when the engine is in idle (saving fuel). The point is that since the other pieces of camshaft are not connected the valves above the other cylinders don't work due to which they are kept unoperated.
4. So the only cylinder that will work is the one where the camshaft rotates above the cylinder.
5. How the camshafts can be connected/disconnected can be done using a switch or depending on the weight in the vehicle that can be controlled electronically/hydraulically.

I'm not sure if the above explains the whole idea of what I have in mind, but I'm willing to give more explanation if you can guide me if this would or would not work. I'm more interested to know the answer, if this doesn't work - why?

Thanks in Advance
