Embodiment

[0044] In order to solve the problem that the power attenuation of the two-stroke engine is serious at high altitudes, resulting in the instability of the intake pressure of the engine at different altitudes, the embodiment of the present invention provides a method for stabilizing the intake pressure of the two-stroke engine. figure 1 As shown, the method can run on the server side, and can also run on the client system carried by drones or cars.

[0045] Take this method running on the server as an example.

[0046] The intake pressure of the engine is related to the intake air volume of the engine. The higher the altitude, the thinner the air and the lower the intake air volume. In order to keep the intake pressure of the engine stable, the intake air volume of the engine should be kept stable. The inventors achieved this through the following methods.

[0047] refer to figure 1 and 2 As shown, the two-stroke engine intake pressure stabilization methods include:

Abstract

In order to solve the problem that the power attenuation of the two-stroke engine at high altitude causes the engine intake pressure to be unstable at different altitudes, the embodiments of the present invention provide a method and system for stabilizing the intake pressure of a two-stroke engine. The method includes: comparing the real-time altitude The altitude pressure data and the preset altitude pressure data are used to obtain the pressure difference between the instant altitude and the preset altitude; the intake air volume value is generated according to the intake air volume data of the two-stroke engine; the boost pressure is generated according to the pressure difference and the intake air volume value controller control signal. The system includes a continuously variable speed governor and a supercharger; the continuously variable speed governor is used to connect with the power output end of the two-stroke engine; the supercharger is used to connect with the actuator of the continuously variable speed governor; The air outlet is used to connect with the air intake of the two-stroke engine through a pipe. In the embodiment of the present invention, the supercharger compensates for the air pressure drop caused by the height increase, so that the two-stroke engine is not affected by the height and attenuates the power.

Description

technical field [0001] The invention relates to the field of aircraft two-stroke engines, in particular to a method and system for stabilizing the intake pressure of a two-stroke engine. Background technique [0002] Two-stroke engines are used in many fields such as small aircrafts, motorcycles, and agricultural and forestry machinery because of their simple structure, high power per liter, light weight, and low cost. [0003] But its stroke nature keeps it from having a dedicated aspirating process like a four-stroke. The suction stroke of the two-stroke engine is to rely on the negative pressure formed in the lower part of the piston cylinder and the crankshaft when the piston moves upward from the bottom dead center (that is, synchronously with the compression of the upward piston) to enter the crankcase. Since the internal volume of the crankcase is greater than the volume produced by the upward movement of the cylinder, the crankcase has a certain influence on the suc...
