Functions of a turbocharger actuator:

Pressure regulationIt 

Controls the boosting pressure of the turbocharger to ensure that the engine has appropriate intake pressure under different operating conditions.

Exhaust gas bypass control

It determines whether exhaust gas should bypass the turbine by going through a bypass channel to adjust the speed and boosting effect of the turbine. It helps reduce turbo lag under certain operating conditions and improve engine operation smoothness.

Protection function

It prevents the turbocharger from operating under overpressure, and protects the engine and the turbocharger against damage. When the pressure exceeds the safety limit, the actuator will take corresponding actions to reduce the boosting pressure.

Optimization of fuel economy

It realizes efficient combustion of the engine in various operating conditions by precisely controlling the boosting pressure, thereby improving fuel economy.

Adaptation to engine operation conditions

It provides an appropriate boosting pressure level based on different operating modes of the engine (such as cruise, acceleration, and idling).

Common failures of a turbocharger actuator:

Stuck actuator: There is a lack of power during acceleration of the vehicle, and the engine failure indicator will light on.

Electrical failure: There is a failure in the actuator circuit, such as a short circuit, open circuit, or sensor malfunction.

Mechanical part damage: Internal mechanical transmission parts, such as connecting rods and gears, have been damaged or deformed.

Sensor failure: A sensor used to monitor the position or pressure of the actuator has failed, preventing the system from obtaining accurate data.

vika turbocharger actuator:

With a modular design, vika turbocharger actuators can be designed independently of motors, thus meeting platform-based production requirements and leading to more consistent product quality.

The circuit board of a vika turbocharger actuator is positioned and welded together with a motor stator, and the motor commutator brush is fixed to the circuit board to avoid direct contact. The benefits include optimized component design and higher durability.
