Newly bought cars have a break-in period. In the meantime, if it is used improperly, the fuel consumption, driving performance and even the service life of the car will be affected. However, it is almost impossible to buy a new car without a break-in period. This is the information that was learned at the inaugural meeting of the Sino-German Cooperation Coordinates Testing Center.
Sun Xueming, dean of the Institute of Metrology and Quality Testing of the Chinese partner of the center, told reporters that the automobile running-in period exists because the precision of the three-coordinate measuring instrument for measuring automobile parts is not high, resulting in the shaft and shaft used in the automobile engine. The set is caused by deviations. This deviation must be removed after a period of travel, due to friction between the shaft and the bushing. In fact, some cars produced in some developed countries have long had no running-in period. The high-precision testing of the center will enable the running-in period of the car to be completed before leaving the factory, which is of special significance to the development of Shenzhen's economy.
Coordinate measuring machines are widely used in machinery manufacturing, electronics, light industry, automotive and other industries. The three-coordinate measuring machine introduced by the center has the world's leading precision and is the leader of similar measuring machines in China. This is undoubtedly a blessing for the Shenzhen machinery industry with an annual output value of 12 billion.
