Abstract
Description
Technical Field
[0001] The utility model relates to the field of engines, in particular to a combustion chamber of an engine cylinder. Background Art
[0002] There is a combustion chamber in the cylinder of the engine. The spark plug introduces high voltage electricity into the combustion chamber and makes it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder and driving the piston to reciprocate up and down. Ordinary combustion chambers fail to burn the gas quickly and evenly after the gas burns and expands, resulting in slow flame propagation and incomplete combustion, and failing to generate sufficient thrust, affecting the performance of the engine, resulting in low power and high fuel consumption. Utility Model Content
[0003] In order to solve the above problems, the purpose of the utility model is to provide an engine cylinder combustion chamber with a reasonable and reliable structure and which can effectively improve the gas combustion efficiency, thereby increasing power and reducing fuel consumption.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an engine cylinder combustion chamber, comprising an engine cylinder, a cylinder hole is arranged in the engine cylinder, a piston is arranged in the cylinder hole, a combustion chamber is arranged at the top of the cylinder hole, and a spark plug is arranged at the top of the combustion chamber, characterized in that: the combustion chamber is trumpet-shaped, and the combustion chamber is divided into a first expansion section, a second expansion section and a third expansion section from top to bottom, the inner wall inclination angle of the first expansion section is controlled between 58°-62°, the inner wall inclination angle of the second expansion section is controlled between 35°-40°, and the inner wall inclination angle of the third expansion section is controlled between 10°-13°.
[0005] The bottom cross-sectional area of the first expansion section accounts for a ratio of 0.5-0.6 of the bottom cross-sectional area of the third expansion section.
[0006] The beneficial effects of the utility model are:
[0007] 1. After the gas in the combustion chamber is ignited by the spark plug, it expands rapidly three times in succession, achieving a sound amplification effect similar to that of a speaker, releasing a huge thrust to drive the piston to move;
[0008] Because the combustion chamber is trumpet-shaped, when the piston moves upward to squeeze the combustion chamber gas, the gas is guided along the top of the piston from the third expansion section to the second expansion section, the first expansion section, and then flows along the inner wall of the combustion chamber. The gas generates a vortex during the movement, making the gas in the combustion chamber more uniform in a short time. After the spark plug is ignited, the gas burns more stably and the flame propagates more quickly.
[0009] Therefore, the structure is reasonable and reliable and has the technical effect of effectively improving the gas combustion efficiency, thereby increasing power and reducing fuel consumption.
[0010] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.
[0014] like Figure 1 , Figure 2 As shown, the present embodiment discloses an engine cylinder combustion chamber, comprising an engine cylinder 1, a cylinder hole is arranged in the engine cylinder 1, a piston 2 is arranged in the cylinder hole, a combustion chamber 3 is provided at the top of the cylinder hole, a spark plug 4 is arranged at the top of the combustion chamber 3, the combustion chamber 3 is trumpet-shaped, and the combustion chamber 3 is divided into a first expansion section 31, a second expansion section 32 and a third expansion section 33 from top to bottom, an inner wall inclination angle B of the first expansion section 31 (the angle between the inner wall inclination and the horizontal line) is controlled between 58°-62°, an inner wall inclination angle C of the second expansion section 32 is controlled between 35°-40°, and an inner wall inclination angle D of the third expansion section 33 is controlled between 10°-13°, so that the gas in the combustion chamber 3 is guided to flow efficiently.
[0015] The bottom cross-sectional area of the first expansion section 31 accounts for 0.5-0.6 of the bottom cross-sectional area of the third expansion section 33. This design allows the gas to expand after combustion and flow from the third expansion section 33 to the first expansion section 31 for compression, which has better compression performance and improves the sufficiency of gas combustion.
[0016] With the above technical solution, the gas in the combustion chamber 3 is ignited by the spark plug 4 and then expands rapidly three times in succession through the first, second and third expansion sections, obtaining a similar sound amplification effect as a speaker, releasing a huge thrust to push the piston 2 to move; because the combustion chamber 3 is in the shape of a trumpet, when the piston 2 moves upward to squeeze the gas in the combustion chamber 3, the gas is guided to flow along the top of the piston 2 from the third expansion section 33 to the second expansion section 32 and the first expansion section 31, and then flows along the inner wall of the combustion chamber 3. The gas generates a vortex during the movement, making the gas in the combustion chamber 3 more uniform in a short time. After the spark plug 4 is ignited, the gas burns more stably and the flame propagates more rapidly; therefore, the structure is reasonable and reliable and effectively improves the technical effect of gas combustion efficiency, thereby increasing power and reducing fuel consumption.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0018] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
