Engine exhaust pipeline of surfboard

Abstract

The invention discloses an engine exhaust pipeline of a surfboard. One end of an engine exhaust pipe is communicated with an engine exhaust opening, and the other end extends out of a cavity of the surfboard; a first filter screen and a first one-way valve are fixedly arranged from one end to the other end in the engine exhaust pipe in sequence; and the first one-way valve allows gas in the engine exhaust pipe to be exhausted but does not allow seawater to enter the exhaust pipe. The first one-way valve and the first filter screen which are installed in the engine exhaust pipe of the surfboard effectively prevent oil liquid from being discharged into the seawater and meanwhile prevent the seawater from entering the interior of the engine along the exhaust pipe, thus the surfboard is environmental-friendly and safe; and an oil-gas separator is arranged in the engine exhaust pipe to ensure that oil and gas in the engine exhaust pipe are separated, thereby ensuring that the waste oil is not discharged into the seawater and meanwhile is not accumulated in the engine exhaust pipe to influence the exhaust of the exhaust pipe.

Description

technical field [0001] The invention relates to a surfboard engine exhaust device, in particular to a surfboard engine exhaust pipeline. Background technique [0002] When the surfboard slides on the sea surface, because the engine cannot fully burn, some oil will be discharged outside the engine with the exhaust gas. If the engine directly discharges the exhaust gas with oil into the sea water, it will pollute the sea water, and because The hull of the surfboard is in the seawater, and the exhaust pipe is completely extended into the seawater. The seawater can easily flow back into the engine along the engine exhaust pipe, causing the engine to burn. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a surfboard engine exhaust pipeline, which has a simple structure, is environmentally friendly and safe to use. [0004] The technical solution adopted by the present invention in order to solve the technical p...
