An internal combustion engine capable of reducing an amount of dust taken from an outside air intake opening, with a simple configuration. The internal combustion engine includes a crankshaft, a cooling air intake device that houses a cooling fan coupled to the crankshaft and that includes a cooling air intake port, and an air cleaner device that feeds outside air to an air suction port to a cylinder, and the air cleaner device includes an outside air intake opening that opens toward the cooling air intake port.
Claims7
An internal combustion engine comprising:
- a crankshaft,
- a cooling air intake device that houses a cooling fan coupled to the crankshaft and that includes a cooling air intake port which opens to an outside of the internal combustion engine, and
- an air cleaner device that feeds outside air to an air suction port to a cylinder, wherein
- the air cleaner device includes an outside air intake opening that opens to the outside and toward the cooling air intake port,
- the air cleaner device includes a cyclone ventilation part that supplies the outside air in a cyclonic state from the outside air intake opening,
- the air cleaner device includes:
- an air cleaner element through which the outside air passes;
- a body member that covers the air cleaner element from a lower side in a gravity direction;
- and a cover member that covers the air cleaner element from an upper side in the gravity direction,
- the cyclone ventilation part is formed by joining the body member and the cover member of the air cleaner device.
