Abstract
An engine has a combustion chamber. An air induction system communicates with the combustion chamber through an intake port. An exhaust system communicates with the combustion chamber through an exhaust port. Intake and exhaust valves move between an opening position and a closing position of the intake port and the exhaust port, respectively. A camshaft actuates either the intake valve or the exhaust valve. The camshaft extends generally vertically. A VVT mechanism changes an angular position of the camshaft. A sensor detects the angular position and generates a signal indicative of the angular position. The sensor is disposed below the VVT mechanism.
