Abstract
An internal combustion engine is provided with a variable valve operating apparatus, for use on a saddle-type vehicle. When a switching drive shaft is longitudinally moved under hydraulic pressure switched by a solenoid valve, a cam mechanism advances and retracts a switching pin. When the switching pin is advanced to engage in a lead groove in a cam carrier, the cam carrier is axially moved while rotating, to switch cam lobes to act on an engine valve. A solenoid valve is disposed on a left or right end in the leftward and rightward directions across the vehicle width, of a front or rear surface of a cylinder head. The solenoid valve is placed in an appropriate location in the cylinder head out of interference with other parts of the engine, thereby making the vehicle small in size.
