Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] The invention provides a digital aviation piston engine fuel atomization injection system, such as figure 1 As shown, it includes housing 1, external socket 2, decoder 3, fuel injection nozzle placement chamber 4, internal oil supply channel 5, oil supply channel temperature sensor 6, thermal bubble channel 7, heating resistor 8, and fuel injection nozzle 9.

[0042] The overall shape of the housing 1 is arc-shaped, and it is divided into three parts from the outside to the inside. The outermost part is the external socket 2, which is the channel connecting the fuel atomization system with the engine ECU, and is responsible for receiving the input signal of the decoder 2. , and at the same time transmit the oil temperature signal of the oil supply channel temperature sensor to the engine ECU. The middle part is a circuit decoder 3 and an internal oi...

Abstract

The invention provides a novel and digitized fuel injection system, and belongs to the field of minitype aviation piston engine fuel injection. The fuel injection system mainly comprises a shell, an external socket base, a decoder, a nozzle placing cavity, an inner fuel-supplying channel, a temperature sensor of the fuel-supplying channel, a hot-bubble channel, a heating resistor and a nozzle; the fluid injecting quantity of system operating cycle for every time can be controlled by controlling the address signal amount. Based on the function of the digitized fuel injection system, the invention also discloses a full digitized fuel atomization injection control method, and the address signal amount and the fuel-injection quantity in each circle of an engine can be confirmed through the method.

Description

technical field [0001] The invention proposes a fuel injection atomization system based on the principle of micro-channel hot bubble injection, which belongs to the field of fuel supply and regulation of small-displacement piston engines, especially the field of fuel injection of small-scale aviation piston engines, and has good consistency of spray atomization effect , with a high degree of integration, meeting the requirements of a small aviation piston engine for a fuel injection system that is lightweight and efficient. Background technique [0002] With the continuous expansion of the application field of UAVs, the performance requirements of small aviation piston engines that provide power for them are getting higher and higher, and its development trend is to have a high power-to-weight ratio, which requires it to have light weight and high efficiency. Small aviation piston engines now basically use carburetor fuel supply. Due to the inevitable short-circuit loss in ...
