| Abstract:Based on detailed analyses of imported engine valve from varied aspects, the domestically produced valve was developed, which met with the same requirements as the imported ones. The imported valves and the domestically produced valves were all installed into the same cylinder and operated for 6 000 h before comparative test. The test results show that the quality of domestically produced valves enjoy the same quality as the imported valves, yet boast much lower price and quicker and easier manufacturing. |
