Dual-purpose fuel gas device for small-sized universal engine

Abstract

The invention relates to a two-purpose fuel gas device for a small-size general-use motor, which comprises a gas source (1), a decompression adjuster (3), a two-purpose fuel blender (6) and a gasoline box (9), wherein an inlet of the decompression adjuster (3) is connected with the gas source (1) through a pipe (2), a dynamic adjusting valve (4) is arranged at the outlet part of the decompression adjuster (3), the other end of the dynamic adjusting valve (4) is connected with the blender (6) through a pipe (5), the gasoline inlet at one side of the two-purpose fuel blender (6) is connected with the gasoline box (9) through a gasoline line (7), an oil way switch (8) is positioned on the gasoline line (7) and is adjacent to the gasoline box (9), the inlet of the two-purpose fuel blender (6) is connected with an air filter and the outlet of the two-purpose fuel blender (6) is connected with the motor. The two-purpose fuel gas device can switch fuel supplying for the motor timely and randomly according to the supplying condition of the fuel, which can reach the condition of combusting gas when the gas fuel exists and combusting gasoline when the gas fuel doesn't exist, thereby the device doesn't influence the dynamic design effect of the prior motor.

Description

technical field [0001] The invention relates to a dual-purpose fuel gas device for a small general-purpose engine, which can separately provide fuel for gas and gasoline, so that the engine can be safe when any fuel of gasoline and liquefied petroleum gas or gasoline and natural gas is provided separately , reliable, and working properly. It is mainly used in small general-purpose engines such as small generator sets, water pumps, etc. for household, civil, and industrial buildings. It belongs to the field of small general-purpose engines. Background technique [0002] At present, the dual-purpose fuel gas device for small general-purpose engines has just started, and there is no perfect product coming out. Some lower-end products mostly use single-fuel gas devices, and the gas mixer in the single-fuel gas device is directly added to the air filter at the front end of the general-purpose carburetor of the original gasoline engine. The working condition is basically normal...

Problems solved by technology

Some lower-end products mostly use single-fuel gas devices, and the gas mixer in the single-fuel gas device is directly added to the air filter at the front end of the general-purpose carburetor of the original gasoline engine. The working condition is basically normal, but because the diameter of the throat of the gas mixer is small, the working condition of the original gasoline is changed, making it difficult to start when gasoline is used as fuel, the engine power
