Main Function: The wastegate actuator controls the turbocharging output and discharges excess exhaust gas from the turbine wheel. It has a spring and a diaphragm. The spring keeps the wastegate closed until the boost pressure reaches the set value, then opens to allow the gas to escape and reduce the boost pressure. 4. Safety Enhancement: Turbo wastegate actuator can control the speed of the turbine, prevent the turbine from overspeed, and regulate the speed of the compressor. This helps protect the turbocharger from unnecessary wear by limiting the maximum boost pressure of the turbocharger to a safe level. 5. Direct Replacement: Simple and fast installation, does not require complicated operations, which is convenient to install and use, effectively saving your time and effort.
