hi,
i'm confuse over the cam angle in the k-pro. Is 0 degree cam angle mean the camshafts is retarded to 0 degree BTDC? is 50 degree cam angle set in k-pro means the camshafts is 50 degree BTDC? could any one gives explanation?
jonathon :?
confuse over cam angle
The cam angle is the intake cam advance measured in crank degrees. The allowable cam angle range is from 0 to 50 degrees.
The intake cam is positioned by an electro-hydraulic mechanism, which uses feedback from the intake cam position to alter the position of a solenoid which in turn rotates the intake cam inside the cam sprocket. Because of the design of the mechanism there is a delay between setting the cam position in the ECU, and the cam physically rotating to this position. This delay is around 0.1 seconds per 10 degrees of rotation.
Warning:
With Honda cams there is a physical stop limiting cam advance to prevent valve to valve contact and valve to piston contact. With after market cams it is up to the manufacturer to ensure that the cam lobes are positioned so that valve to valve and valve to piston contact is not possible. Because the cam control mechanism uses a closed-loop feedback system, limiting the cam position in the ECU will not guarantee that the cam position will not exceed what is set in the ECU. Because of this all cams must have a physical stop to prevent valve contact.
