Abstract
An internal combustion engine that can ensure an adequate cooling performance by using a small number of component parts, and can be minimized in size. The cooling device includes a boiling water cooling device including a water jacket, coolant piping, steam piping and a radiator, an air cooling fan connected to one end of a crankshaft projecting from an outer surface of the engine main body, and a cover member provided on the engine main body so as to cover the air cooling fan, and define a cooling air passage extending to a radiator core.
Claims6
An internal combustion engine comprising an engine main body defining a water jacket therein, and a cooling device for cooling a coolant in the water jacket,
- the cooling device comprising:
- a radiator provided such that a large part of the radiator is located above an upper end of the water jacket;
- steam piping communicating an upper part of the water jacket with the radiator to forward the coolant that has boiled in the water jacket to the radiator;
- coolant piping communicating a lower part of the radiator with a lower part of the water jacket to forward the coolant that has been cooled in the radiator to the water jacket;
- an air cooling fan connected to one end of a crankshaft projecting from an outer surface of the engine main body;
- and
- a cover member provided on the engine main body so as to cover the air cooling fan, and define a cooling air passage extending to a heat emitting part of the radiator,
- wherein an outer surface of the engine main body is provided with a plurality of fins, and the cover member defines a cooling air inlet on a side of the fins.
