What are the two types of waste gates?

Explanation:
Waste gates regulate turbo boost by diverting exhaust away from the turbine, and the basic distinction is whether the gate opening is fixed or adjustable. A fixed wastegate uses a pre-set spring to hold the gate at a single opening; once the boost reaches that set point it opens and tends to maintain roughly that level, regardless of further throttle. This setup is simple and reliable but less adaptable across speeds and load. A variable wastegate uses an actuator (vacuum, hydraulic, or electronic) to continuously adjust the gate opening. This allows precision control of boost across the engine’s operating range, providing higher or more stable boost and reducing the risk of over-boost by adapting to changing conditions. Other descriptions like manual vs automatic, or electronic vs hydraulic, refer to how the wastegate is actuated rather than what type of wastegate it is, so they don’t define the fundamental category.
