Abstract

The invention belongs to the technical field of internal combustion engines, and discloses a liquid fuel injection device for a liquid fuel internal combustion engine, comprising: an injection base, a flexible pipe, a nozzle and a traction mechanism; the flexible pipe is fixed on the injection base, and the nozzle It communicates with the first end of the flexible pipe; the traction mechanism is arranged on the spray base and connected with the spray head. The liquid fuel injection device for a liquid fuel internal combustion engine provided by the invention can realize the adjustment of the injection angle, so that the injection angle can be adjusted following the position change of the piston.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a liquid fuel internal combustion engine and a liquid fuel injection device thereof. Background technique [0002] In the prior art, the injection angle of the injection device of the liquid fuel internal combustion engine is fixed. In order to achieve a good spray atomization effect and avoid wet walls, a multi-hole design is carried out on the nozzle of the injection device, and the direction of each hole is different. At the same time, a higher injection pressure is used to achieve the goal. Since the volume of the cylinder is changing all the time due to the impact of the reciprocating motion of the piston, the fuel injection device with a fixed angle can only compromise an optimal injection angle. However, when the piston is in the upper position, the fuel is easily sprayed onto the piston to form an oil film, which leads to insufficient combustion, and ...
