Description
Technical Field
The invention relates to the field of gasoline carburetors, in particular to a control method of fuel injection quantity of a carburetor for an unmanned aerial vehicle.
Background
A carburetor is a mechanical device for mixing gasoline and air and supplying the mixture to an engine after atomization, but the existing gasoline type carburetor cannot well control the fuel injection quantity of an internal fuel injection nozzle, so that fuel injection can not be accurately performed on the engine, the carburetor which can not accurately control the fuel injection quantity can bring great fuel waste in the using process, excessive mixed gas is conveyed to the engine, and the problem of high fuel consumption is caused.
Disclosure of Invention
The technical problem to be solved by the present invention is to solve the above-mentioned deficiencies of the prior art,
a method for controlling the fuel injection amount of a carburetor used for an unmanned aerial vehicle is provided.
In order to achieve the purpose, the invention provides the following technical scheme: the control method of the fuel injection quantity of the carburetor for the unmanned aerial vehicle is characterized by comprising the following steps of:

s2: the middle part of the carburetor is provided with a temperature and pressure sensor, one end of the temperature and pressure sensor extends into the carburetor, the other end of the temperature and pressure sensor is connected with the ECU, and the temperature and pressure sensor is used for feeding back an air inlet pressure signal and a temperature signal in a cavity of the carburetor to the ECU;
the control method of the fuel injection quantity of the carburetor for the unmanned aerial vehicle can be further set as follows: the stepping motor is a hybrid stepping motor, and the step angle of the stepping motor is 1.8 degrees.
By adopting the technical scheme, the opening angle of the throttle valve is controlled by the stepping motor, the reaction time is short, and because the hybrid stepping motor with the step angle of 1.8 degrees is adopted in the invention, the rotating speed is high, the opening/closing reaction time of the throttle valve is further reduced, the ECU controls the opening/closing angle of the throttle valve according to the temperature and the air inlet pressure in the carburetor cavity fed back by the temperature and pressure sensor, and controls the oil injection quantity of the oil nozzle by the temperature signal and the air inlet pressure signal, so that the oil injection quantity is more accurate, and the oil consumption of the unmanned aerial vehicle is reduced.
The invention has the beneficial effects that: the fuel injection quantity control is more accurate, and the fuel consumption that unmanned vehicles promoted because of excessive oil spout is showing and is reducing.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
