Abstract The invention relates to a four-stroke internal combustion engine. A four cycle engine in which an intake passage having at least two intake valves (8,9) and two intake ports are provided per cylinder (1), the intake ports are branched from a common intake pipe (13). Each of the intake ports is guided to upper sides of the intake valves (8,9), one of the two intake ports is constituted as a charge loading port (11), and the other is constituted as a volume port (12). A throttle device (21) for intake amount control is interposed in the intake passage, and the intake passage is connected with a fuel-supplying device. A fuel-supplying device is constituted of a joint carburetor (14) for both intake ports of a charge loading port and a volume port. The carburetor(14) is characterized by disposing both the intake ports in an area branched from the intake pipe (13).
