[0007] As a preferred solution of the present invention, a plurality of limiting holes distributed in an annular shape are provided on the bottom of the cylinder head body.

[0008] As a preferred solution of the present invention, an air inlet is provided on the front side of the cylinder head body, and an air outlet is provided on the rear side of the cylinder head body.

[0009] As a preferred solution of the present invention, the air inlet and the air outlet are both connected to the combustion chamber.

[0010] Compared with the prior art, the beneficial effect of the present invention is that the present invention provides a notch so that after the cylinder head body is installed, the staff can judge whether the cylinder gasket is installed through the notch without disassembling the cylinder head body for observation, thereby improving the installation efficiency of the cylinder head body, and the provided indicator mark allows the staff to quickly find the position of the notch.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6The utility model provides a technical solution: an engine cylinder head, comprising a cylinder head body 1, and a cylinder head mounting surface 10 arranged at the bottom of the cylinder head body 1. The cylinder head mounting surface 10 is a plane to ensure the sealing of the cylinder head body 1. The interior of the cylinder head body 1 is provided with a plurality of combustion chambers 11. The inner side wall of the cylinder head body 1 is integrally formed with a fixing column 4. The fixing column 4 is penetrated by a second mounting hole 5. The bottom of the second mounting hole 5 is provided with a notch 7. When the cylinder head body 1 is installed on the cylinder block, the staff can directly observe whether the cylinder gasket is installed through the notch 7 without having to disassemble the cylinder head body 1 to confirm , which improves the installation efficiency of the cylinder head main body 1. An indicator mark 6 is provided on the outside of the second mounting hole 5. The indicator mark 6 helps the staff to quickly find the position of the notch 7. The indicator mark 6 can be a raised setting or a recessed setting. A plurality of first mounting holes 3 distributed in a rectangular shape are provided on the cylinder head main body 1. When installing the cylinder head main body 1, the bolts are passed through the first mounting holes 3 and the second mounting holes 5 to fix the cylinder head main body 1 on the cylinder block. The first mounting holes 3 and the second mounting holes 5 are respectively along the edge of the cylinder head mounting surface 10, thereby ensuring that the bolts fixing the cylinder head main body 1 are evenly force applied, making the installation of the cylinder head main body 1 more stable.

[0020] Among them, the cylinder head body 1 is provided with an injection hole 9 inside, which is used to install the injector. The fuel enters the combustion chamber 11 in the form of atomization through the injector, and is fully mixed with the air to form a uniform mixture, providing good conditions for the combustion process. The injection hole 9 is located in the center of multiple combustion chambers 11.

[0021] The bottom of the cylinder head body 1 is provided with a plurality of limiting holes 8 distributed in a ring shape, and the limiting holes 8 are used to limit the cylinder head body 1 so that the cylinder head body 1 will not deviate after being installed on the cylinder block.

[0022] Among them, the front side of the cylinder head body 1 is provided with an air inlet 2, which is used to introduce air into the combustion chamber 11, and the rear side of the cylinder head body 1 is provided with an air outlet 12, which is used to discharge the exhaust gas after combustion.

[0023] The air inlet 2 and the air outlet 12 are both connected to the combustion chamber 11 .

[0024] Specifically, when installing the cylinder head body 1, the bolts are passed through the first mounting hole 3 and the second mounting hole 5, so that the cylinder head body 1 can be fixed to the cylinder block. Then, the position of the notch 7 can be quickly found according to the indication of the indicator mark 6. By observing through the notch 7, it can be determined whether the cylinder gasket is installed, without the need to disassemble the cylinder head body 1 for observation.
