Actuators for variable turbine geometry (VTG)

MAHLE electric actuators for turbochargers with variable turbine geometry (VTG) optimally adjust the incident flow from the turbine for current operating conditions, ensuring high performance, low emissions, and low fuel consumption.

Actuators for variable turbine geometry (VTG)

MAHLE has specifically designed these electric actuators to meet the requirements of modern combustion engines: The models for VTG applications are therefore extremely compact and lightweight, weighing in at less than 250 g. They also allow for maximum flexibility in vehicle applications thanks to a generous adjustment angle of up to 130° and an application temperature range of −40°C to +160°C as standard.

The actuators are dust-proof and protected against water ingress during high pressure or vapor cleaning of the engine compartment, for example. The actuator is driven by a DC motor with a three-stage transmission. Position feedback is provided via a contactless Hall sensor system with digital or analog output and control via the engine ECU.
