Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0023] See attached Figures 1 to 7 , the twin-cylinder two-stroke water-cooled engine that integrates the muffler and the cooling system in the figure includes a twin-cylinder two-stroke water-cooled engine 7, a water-cooled muffler 13 and a cooling system 8; it is characterized in that:

[0024] Described two-cylinder two-stroke water-cooled engine 7 comprises crankcase 704, starter motor 708 of starting mechanism, carburetor 710 and engine cylinder 709; The one-way bearing mounting sleeve 715 of the 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;

[0025] Two engine cylinders 709 are arranged symmetrically on both sides of the crankcase 704, and the center line of the engine cylinder 709 coincides with the center line o...

Abstract

The invention relates to an engine for a powered surfboard or a motorboat and discloses a silencer and cooling system integrating double-cylinder two-stroke water-cooled engine. The silencer and cooling system integrating double-cylinder two-stroke water-cooled engine comprises a double-cylinder two-stroke water-cooled engine body, a water cooling silencer and a cooling system, wherein the cooling system comprises a positive pressure cooling water inlet pipe communicated with the positive pressure cavity of a water spray boosting pump, the positive pressure cooling water inlet pipe passes through the shell of the water spray boosting pump, the water inlet of the positive pressure cooling water inlet pipe is opposite to the water flow direction of the water spray boosting pump, the water outlet of the positive pressure cooling water inlet pipe is communicated with the water inlet of a cooling water pipe, a three-way pipe joint is fixed at the water outlet of the cooling water pipe, and the other two ports of the three-way pipe joint are respectively communicated with a cold water inlet pipe and a cooling water inlet in the two-stroke water-cooled engine body. Because the silencer and cooling system integrating double-cylinder two-stroke water-cooled engine is compact in structure, the silencer and cooling system integrating double-cylinder two-stroke water-cooled engine reduces the volume, lowers the weight and improves the rotating speed and output power.

Description

technical field [0001] The invention relates to an engine for power surfboards or motorboats, in particular to a two-cylinder two-stroke water-cooled engine integrated with a muffler and a cooling system, which has a compact structure, reduced volume, reduced overall mass, 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 hollo...
