In the figure: 1. an air inlet pipe; 2. an air outlet pipe; 3. a cylinder cover; 4. a piston; 11. a protrusion; 21. and a diversion trench.
Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.
Referring to fig. 1 to 5, in an embodiment of the present utility model, a combustion chamber structure includes a cylinder body, a cylinder cover 3 is disposed on the top of the cylinder body, the top of the cylinder cover 3 protrudes upwards 11, and the cylinder cover 3 is divided into an air inlet area and an air outlet area;
wherein, the air inlet area of the cylinder cover 3 is provided with a plurality of diversion trenches 21, an air inlet pipe 1 is welded at the diversion trench 21, an air outlet pipe 2 is welded on the air outlet area of the cylinder cover 3, and a bulge 11 is arranged at the welding position of the air inlet pipe 1 and the diversion trench 21; a piston 4 is slidably arranged in the cylinder, the piston 4 having a spherical top surface.
As shown in fig. 4, when the gas enters the cylinder from the gas inlet pipe 1, the protrusion 11 and the flow guiding groove 21 on the gas inlet pipe 1 guide the passing gas, so that the gas more intensively enters the cylinder to form intensively strong gas flow, thereby improving the tumble ratio and the turbulent energy.
As shown in fig. 5, during the compression process, the spherical top surface of the piston 4 can guide the air flow to do circular motion, thereby promoting the formation of tumble and improving the combustion efficiency.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
The foregoing is merely illustrative of the structures of this utility model and various modifications, additions and substitutions for those skilled in the art can be made to the described embodiments without departing from the scope of the utility model or from the scope of the utility model as defined in the accompanying claims.
