Description

technical field

[0001] The invention relates to a valve seat ring installation structure and installation method, in particular to a valve seat ring installation structure and installation method that cooperate with an internal combustion engine / engine valve. Background technique

[0002] In the prior art, the common structure of the cylinder head A of the internal combustion engine / engine and the valve seat ring is as follows: figure 1 Shown: the air passage 12 of the cylinder head A is processed at the joint (air outlet) of the engine combustion chamber to form a stepped valve seat ring hole 11. And, if figure 2 As shown, the valve seat ring 13 is pressed into the above-mentioned valve seat ring hole 11 .

[0003] The valve seat ring 13 plays a very important function in the working process of the internal combustion engine-sealing the valve and transferring the heat of the valve. The heat of the valve comes from the combustion of the mixture in the engine cylinder. If...
