The ECM controls the camshaft phase angle in order to attain optimal valve timing that suits the engine load and engine speed.Įxhaust valve lift curve (at most advanced angle) The detected phase angle is calculated using the intake camshaft position sensor signal and the exhaust camshaft position sensor signal. Pressure to be divided into the retarded chamber and the advanced chamber, as well as allows the phases of the intake camshaft and the exhaust camshaft to be continuously changed. Changing the spool valve position allows the oil.Sends the duty signal to the intake engine oil con- trol valve and exhaust engine oil control valve as well as controls the spool valve position.
