dt235sd posted a camshaft specifications ID chart.
What does it all mean?
Duration @.050
Advertised duration
Valve lift
Cam lift
center line
Rocker arm ratio.
So as I understand it. It's all about air flow and the amount of time intake and exhaust are open at the same time.
Based on this limited understanding I have made the following SWAG.
Center Line = is where the center of the lobe is located. For example CCS-5 has an Inrake CL of 108 degree and exhaust center line of 110 degree so there is a 2 degree amount of shared time in which both are open.
Duration @.050= No idea.
Valve lift= How high the valve opens . I.E. CCS-5 Intake opens 4 tenths.
Cam Lift= I would assume how high the lobe lifts; but shouldn't it be the same as the valve lift. So.. No Idea.
Rocker arm ratio= No Idea.
Looking forward to increasing my knowledge.
Thank you
Chris
