Aircraft engine and heat dissipation control method thereof

Abstract

In the field of unmanned aerial vehicles, in order to adjust the working temperature of the engine simply and conveniently, the present invention discloses an aircraft engine, comprising: a cylinder block; a radiator fin, which is connected to the top of the cylinder block; The flow fin can change the flow direction of the airflow that flows through the guide fin and blows to the cylinder block; the adjustment device can adjust the deflection angle of the guide fin relative to the heat sink; the temperature sensor is arranged on the cylinder block; the application of the above aircraft engine can be simple The working temperature of the engine can be adjusted conveniently, and the invention also provides a method for controlling heat dissipation of the engine.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an aircraft engine and a heat dissipation control method thereof. Background technique [0002] In the current civil drones, heavy oil engines are more and more used. Compared with gasoline engines, heavy oil engines have good durability, strong load capacity, high cost performance, high safety, and superior high-altitude performance. advantage. [0003] However, the working temperature of the heavy oil engine needs to be controlled within a specific range. If the working temperature of the engine is lower than the specified temperature range of the engine, it will cause insufficient combustion of the heavy oil and reduce the working efficiency of the engine; if the working temperature of the engine is higher than its specified temperature range , it will cause the engine piston and the cylinder to be too tight, and the inner wall of the cylinder will be pulled; therefore...

Problems solved by technology

[0003] However, the operating temperature of the heavy oil engine needs to be controlled within a specific range. If the operating temperature of the engine is lower than the specified temperature range of the engine, it will cause insufficient combustion of the heavy oil and the engine's working efficiency will decrease; if the operating temperature of the engine is higher than the specified temperature range , will cause the engine piston to cooperate too tightly with the cylinder, and the inner wall of the cylinder will be strained; therefore, controlling the working temperature of the heavy oil engine is very important to ensure the work of the heavy oil engine
