Hi, Iím Matt and am currently studying motorsport at Derby University.
As part of my power train module, I have been set an assignment, based around valve timing on different engines. I have to base my research on a 2 valve Hemi engine, and a 4 valve pent roof.
I decided, after a little research, that the Alfa V6 3.0 litre seems to be an excellent engine to base my studies on, because the 2 valve and 4 valve [per cylinder] versions are based on the same engine.
To construct my valve timing diagrams, I need to find out when the Alfa exhaust and inlet valves open and close, based on crank angle. For example, on an engine that consistently achieves complete combustion, the exhaust valve can be opened at about 40 degrees before BDC.
I hope Iíve explained this in a way that you can understand! Iíve never been very good at explaining things!
Hereís a link to an example of a valve timing diagram so you can see what I mean: http://wps.com/AMC/Rambler-327/The%2...s/v8-fig30.jpg
Any help you can give me would be much appreciated,
Thanks a lot,
