When the engine speed and load (throttle opening) are low, the amount of waste gas is small, and all the exhaust gas will be guided. Lead to the turbine (Turb i ne) to drive the operation of the turbocharger; when the speed and load (throttle opening) reaches a certain amount, the exhaust gas is large enough to drive the turbine into the optimal efficiency range, driving compression The Compressor qt emits high pressure. Once the target pressure is reached, the wastegate is turned on to adjust the amount of exhaust gas that drives the turbine to prevent the rotation speed and load (throttle opening) from rising continuously, causing the turbine blade tip speed to exceed the speed of sound. The resulting supersonic vibrations damage the turbine blades and casing, and excessive boosting can also burden the engine. The opening of the wastegate opens the pressure guide r of the compression turbine outlet to an actuator, and drives the elastic body as a driving force through the air pressure to actuate the actuator. When the pressure reaches a certain level, the pressure is reached. Acting on the diaphragm inside the actuator, greater than the elastic force of the elastic body, the wastegate can be pushed through a connecting rod. When the pressure is increased, the pressure acting on the actuator is also increased, pushing the exhaust gas. The more exhaust gas that the door exhausts, the more the rotational speed of the drive turbine is controlled. [0003] Please refer to FIG. 1 , which is a schematic structural view of a conventional actuator. As shown in the figure, a conventional actuator 50 includes a bullet form number A0101 connected to an adjustment link 53. / A total of 15 pages M397458 -- November 15, 099 nuclear replacement of the page body pressed diaphragm 51, a pressure-bearing elastic body 52 and a pressurized pressure port 5 5, the adjustment link 53 through the conventional The actuator 50 is coupled to a screw 54 for adjusting the preload of the pressure-receiving elastic body 52. The screw 54 is coupled to a crank 56 at the other end of the adjusting link 53 and is coupled to the crank 56. Driving the turbine wastegate 61 of the turbine 60, when the boost value is too large, the air pressure from the boost pressure port 55 presses the elastomer pressing diaphragm 51 to push the adjusting link 53 to interlock the crank 56 to open the turbine. The wastegate 61 exhausts a portion of the exhaust gas that drives the turbine 60 to control the rotational speed of the turbine. [0004] However, the general turbocharged engine uses a conventional exhaust pressure relief valve. Under a certain negative load, the intake negative pressure is greater than zero, and the pressure is continuously increased as the load becomes larger, thereby affecting fuel consumption. W -Λ-» ^
