Embodiment Construction

[0017] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0018] See attached Figures 1 to 3 , the improved single-cylinder two-stroke water-cooled engine in the figure includes a crankcase 704, a starter motor 708 of a starting mechanism, a carburetor 710 and an engine cylinder 709; it is characterized in that: the other end of the crankshaft output end of the crankcase 704 is fixed with One-way bearing 706, the one-way bearing mounting sleeve 715 of the one-way bearing 706 is connected with the output shaft 721 of the planetary gear reducer 707, and the input shaft of the planetary gear reducer 707 is the output shaft of the starter motor 708;

[0019] The crankcase 704 on crankshaft both sides is provided with engine cylinder 709 and carburetor 710, and the centerline of this engine cylinder 709 coincides with the centerline of crankcase 704, and the centerline of carburetor 710 and the centerline of crankcase 7...

Abstract

The invention relates to an engine for a powered surfboard or a motorboat, in particular to an improved single-cylinder two-stroke water-cooled engine. A one-way bearing, a planetary speed reducer and a starting motor in an engine starting mechanism are arranged on a line overlapped with a central line of an engine crankshaft, and a central line of a carburetor is arranged at the position, overlapped with a central line of a crankcase, on one side of the crankcase, so that the overall height of the engine is reduced. Due to the fact that the structure is compact, the size and the overall weight of the improved single-cylinder two-stroke water-cooled engine are reduced, the rotation speed is increased, and the output power is improved.

Description

technical field [0001] The invention relates to an engine for power surfboards or motorboats, in particular to an improved single-cylinder two-stroke water-cooled engine with compact structure, reduced volume, reduced overall height and quality, and improved rotational speed and output power. Background technique [0002] Surfing is popular for its thrills and effective physical exercise. Ordinary surfboards must borrow the thrust of wind and waves before they can be used. When there is no wind and waves or the wind and waves are small, the surfboard will lose its due utility. In order to realize surfing without wind waves or when the wind waves are small, a kind of power surfboard in the prior art uses an engine as power, which can surf on the sea surface or drive on a calm water surface; this type of power surfboard generally Including the hull assembly, power unit, joystick, main empennage, the hull assembly is a prolate oval streamlined hollow structure, the upper middl...
