Abstract
To provide a layout structure of a hydraulic control valve for a valve train in an internal combustion engine which can reduce the influence of heat from the cylinders and can avoid the impairment of the external appearance of the internal combustion engine. An internal combustion engine has a valve operation characteristics changing mechanism that changes the operation characteristics of at least one of an intake valve and an exhaust valve. A hydraulic control valve for a valve train controls the pressure of a hydraulic fluid supplied to the valve operation characteristics changing mechanism. The hydraulic control valve is located on the left side surface of right and left crankcases that support and cover a crankshaft at a position below cylinders.
