Abstract
An engine with dependent intake cams requires a different method and formula to determine the phase of the intake cams. The exhaust camshaft drives the intake camshaft and so the intake cam position is dependent upon the exhaust cam position. The present invention provides a VCT cam timing system utilizing calculation of intake phase for dual dependent cams.
