Background
With the development of the times, the requirements of end customers on the power performance, the oil consumption and the post-treatment of the engine are more and more strict, which also prompts the generation of the bypass supercharger. Compared with the traditional supercharger with a fixed cross section and without bypass, the supercharger with the bypass valve can allow a smaller volute to be selected to improve the operation efficiency of the supercharger, so that the performance of an engine is improved, and the oil consumption is reduced. Meanwhile, the supercharger capable of being bypassed can bypass partial waste gas under the condition of high expansion ratio of the engine to reduce the rotating speed of the supercharger, so that the low-cycle fatigue failure of the supercharger is reduced, and the durable service life of the supercharger is prolonged.
In order to achieve the above function, an exact match between the supercharger and the engine is required to determine when the wastegate valve should perform the bypass function, i.e., to determine the pressure at which the bypass valve opens. If the waste gate valve opens too early, the low speed performance of the engine will be affected, otherwise there will be the risk of overspeed of the supercharger, increasing the risk of low cycle fatigue failure. After the matching of the supercharger and the calibration of the engine are completed, the performance of the engine is completely fixed, and the opening pressure of the waste gas bypass valve is determined accordingly.
In order to control the opening pressure of the bypass valve of the volume production supercharger to be consistent with the original matching, the precision of the setting pressure of the production line supercharger needs to be strictly controlled, and meanwhile, the production efficiency cannot be influenced.
