Electronic Actuators (Hella)

Electronic Actuators (Actuation) in comparison to pneumatic actuators provide a much faster response and a more responsive, precise control for VNT turbochargers.

Electronic actuation is a growing trait of turbocharger control for both passenger and commercial vehicles with diesel engines from 1.4L. Modern turbochargers tend to have electronic actuators and they can be identified as a ‘black box’ which would be mounted onto the compressor housing of the turbocharger which would be connected to the VNT.

This type of actuation offers faster response then its pneumatic opposite. Turbo control is a lot more precise due to the position sensing. This therefore helps to improve engine performance and fuel economy.
