Electronic fuel injection engine of unmanned helicopter

Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to an electronic fuel injection engine of an unmanned helicopter. The unmanned helicopter electronic fuel injection engine includes: generator, starting chainring, engine block, spark plug, electronic injection system, output shaft, cooling fan, cooling water tank, the starting toothing is arranged below the generator, and the Spark plugs are arranged on the side of the engine block, and the electronic injection system includes: oil supply system, air filter system, and electronic control system (ECU). , the output shaft is arranged under the engine block and is connected with the cooling fan, and the cooling water tank is installed under the cooling fan. Compared with the traditional mechanical carburetor, the electronic fuel injection engine of the unmanned helicopter provided by the present invention has stronger power, lower emission, stronger environmental adaptability, and longer battery life of the unmanned aerial vehicle system.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an electronic fuel injection engine of an unmanned helicopter. Background technique [0002] Existing unmanned helicopter engines use mechanical carburetors, which can only set the air-fuel ratio under high-speed and low-speed conditions. The parameters are relatively fixed, the flexibility is poor, and the incidence of rich and poor oil is high. There is basically no adaptability. Under the conditions of low temperature and high altitude, the starting performance of the engine is poor, the power is poor, the fuel consumption is high, and the adaptability is poor. For the unmanned helicopter's self-weight-sensitive structure, it means that the load capacity of the whole machine becomes smaller and the battery life is shorter. Contents of the invention [0003] In view of the above defects of the prior art, the electronic fuel injection engine of the unmanned he...
