guys I really need some help here i got a presentation on about camshaft next I still dunno what to talk about -surr can anybody tell me how you change cam lobe to get the torque to lower RPM and pls gimme some tips on what to present ;(
I would say the materials used to make it. Since its like one piece in the engine, its very crucial. Also different engineering designs...the accuracy of the shaft itself. What else is attached to the camshaft=) hehe XD Do like HIstory, materials used ton construct it, how to service it..cuz it does wear out =), but i guess not as much. As for the Rpms etc torque i think those are controlled by the Cam gears. Also i just remembered =) THE TOOLs needed to measure the camshaft to make sure its in spec. When building engines to measure runout etc is important and wear. Tools like for example mircometer, vernier caliper etc. ^__^ thats about all i can say for now. GL on your work.
check websites from Tomei. they have some pretty nice explainations. I hope you're explaining the solid cam design. The variable cam is quite different.
Late answer, but as with ways of getting more power, the answer is to get more air into the chamber. With low rpms, air is moving slow, you want your camshafts to provide you with faster air velocity to squeeze in more air, you accomplish this by going with smaller overall cams, but you lose top end as a compromise. Larger cams for top end because it allows for more air volume to enter the chamber. That's the general idea anyways. Obviously air velocity and volume are closely related and cams are also not the only component that is attributed to those characteristics. Determining between changing duration or lift really depends on the design of the overall system.
