Problems solved by technology

But at present there are not as many filling facilities as there are refueling facilities, and the problem of inconvenient filling will not be solved for a long time in the future. In addition, motorcycles (including three-wheeled motorcycles) cannot carry heavy loads in order to store more gas. Large cylinders (unlike gasoline tanks are lighter), so the mileage of gas motorcycles must be limited. In places where gas cannot be added, if the gas is suddenly used up, the car will break down, which will bring great harm to the user. the inconvenience

Embodiment Construction

[0016] The gas-gasoline dual-use controller for small engines uses gas as fuel, and the gas must be packed in a special container under pressure. When in use, it is decompressed by the pressure-reducing and stabilizing device and provided to the controller for use, and the gasoline valve must be closed. Gasoline can only be used after the gas is used up or the gas valve is closed.

[0017] The plunger 1 is larger than the conventional one, and the air needle 3 and the oil needle 13 are installed on the plunger at the same time, and rise and fall synchronously with it. The regulating pipe 2 protrudes and is installed in the entire throat of the body 4 . The gas measuring hole 5 is designed by the required maximum gas volume, and is screwed with the body, and the regulating tube is supported to make it reliably fixed. The front end of the air needle 3 is designed to be tapered, which is convenient to be loaded into the adjusting tube together with the plunger. The middle part i...

Abstract

The invention relates to a fuel gas and gasoline dual-use controller for a small engine, which is more suitable for motorcycles and the like having variable torques and rotation speeds. The dual-use controller controls the flow rate of fuel gas and gasoline through a gas pin and a gasoline pin arranged on the same plunger; and the gas pin arranged on the plunger correspondingly opens orifices of a regulating tube along with the change of the plunger position when the fuel gas is used, and the number of the opened orifices makes fuel gas amount optimally matched with air amount to supply ideal air-fuel ratio to the engine all the time. The dual-use controller is same as a prior plunger type carbureter and has no change in structures and working process when the gasoline is used, The arranged double-solenoid valve and magnetor synchronously control circuit, which not only makes opening and closing of the fuel gas consistent with the working condition of the engine, and but also solves the problems of blowout and downtime during quickly accelerating speed.

Description

Technical field [0001] The invention relates to a gas and gasoline dual-purpose controller for small engines. Said that the gas involved is mainly natural gas, petroleum gas and so on. Background technique [0002] Our company's "motorcycle gas mixing regulator" (patent number: 200620132422.5) can provide the required ideal mixture under various working conditions of the engine, so that the engine can always work in an ideal state, and the gas consumption is low , less exhaust gas emission, safe and reliable use, and low manufacturing cost, it can adapt to different air source requirements by replacing the corresponding "regulating tube". But at present there are not as many filling facilities as there are refueling facilities, and the problem of inconvenient filling will not be solved for a long time in the future. In addition, motorcycles (including three-wheeled motorcycles) cannot carry heavy loads in order to store more gas. Large cylinders (unlike gasoline tanks are ...
