With the continuous strengthening of the internal combustion engine, the working conditions of the main components of the gas distribution system are increasingly harsh. In order to better adapt to this situation, measures must be taken to make the relevant parts or related parts of the organization meet the requirements of intensified internal combustion engines. In recent years, at home and abroad to strengthen the internal combustion engine, the valve with the measures adopted by the body, involving new materials, new structures, new technologies and new processes. The truth of these measures
