Abstract

The invention relates to an engine for a powered surfboard or a motorboat and discloses a double-cylinder two-stroke water cooled engine. The double-cylinder two-stroke water cooled engine comprises a crankcase, a starting motor of a starting mechanism, a carburetor and two engine cylinders, wherein the two engine cylinders are symmetrically arranged on two sides of the crankcase in a staggering mode, and the central lines of the engine cylinders are overlapped with the central line of the crankcase; the carburetor is located at the top of the crankcase and communicated with the gas inlet of the crankcase through a gas inlet pipeline, and a gas inlet leaf valve is arranged between the gas inlet pipeline and the gas inlet of the crankcase; bracket mounting holes for connecting with a fixed frame in an engine cabin are formed in the crankcase and engine cylinder shells, and the engine cylinder shells are provided with cooling water outlets, cooling water inlets and exhaust guide pipes communicated with the cavities of the engine cylinders. Because the double-cylinder two-stroke water cooled engine is compact in structure, the volume is reduced, the overall weight is lowered, and the rotating speed and output power are improved.

Description

technical field [0001] The invention relates to an engine for power surfboards or motorboats, in particular to a twin-cylinder two-stroke water-cooled engine with compact structure, reduced volume, reduced overall mass, and increased 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 middle part of the hull assemb...
