Automobile cylinder cover

Abstract

The invention provides an automobile cylinder cover. The outer part of the automobile cylinder cover comprises a body, a plurality of cooling liquid inlets and a cooling liquid outlet, wherein the cooling liquid inlets and the cooling liquid outlet are connected through a water cavity which is formed in the body; the cooling liquid inlets are formed in a heat concentration region; the cooling liquid outlet is formed at the rear end of the cylinder cover; an anti-freezing plug is also arranged in the water cavity and consists of a hollow plug body and a plug head of which one end is connected with the plug body; the other end of the plug head is connected with a water cavity hole of the water cavity; and the plug head is provided with a through hole which is communicated with the cavity of the plug body. Through the technical scheme provided by the invention, temperature in the cylinder cover can be rapidly and uniformly reduced, the cooling effect can be improved, and expansion pressure caused by freezing the cooling liquid can be released to protect the cylinder cover from damage.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile cylinder head. Background technique [0002] The cylinder head of a car engine is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. [0003] It is often in contact with high-temperature and high-pressure gas, so it bears a large thermal load and mechanical load. Therefore, the cooling problem of the cylinder head of the automobile engine must be considered. In order to keep the engine working at a suitable temperature, the car engine has a cooling system to reduce the combustion chamber and exhaust temperature. [0004] The water-cooled engine cooling system uses coolant as the cooling medium. The low-temperature coolant is extracted from the radiator by the water pump. After pressurization, it enters the cooling water jacket of the engine block through the pipeline. The coolant absorbs heat from the engi...

AI Technical Summary

Problems solved by technology

The cooling system of the cylinder head generally has two return water chambers, which can easily cause the flow and circulation of the coolant to be disturbed and the cooling temperature to be uneven, thus affecting the cooling effect

[0006] In addition, the cooling system of the engine cylinder head uses coolant for cooling. When the temperature of the coolant is too low, it will freeze and expand. engine failure

[0007] Therefore, in the process of carrying out the invention of the present invention, the inventor found that there are at least the following problems in the prior art: the existing cylinder head cooling system has two return water chambers, the cooling temperature is uneven, the cooling effect is affected, and it is easy to Malfunction due to low coolant temperature
