Emission control

Electric actuators for emission control on truck and off-highway engines

We believe in producing sustainable mechatronics to preserve the environment through the development of proven, robust actuation solutions for powertrains. Our expertise covers the entire powertrain, from air intake to exhaust pipe, including the combustion chamber environment.

The Sonceboz approach

Controlling gas or PM emissions, or dosing an air flow require an accurate and quick motion system. Our electronically commutated actuators enable precise positioning of a valve. They have integrated CAN bus control electronics and they operate in a supply voltage range between 9V and 60V.

Our mechatronic solutions can deliver high peak torque values – up to 20 Nm. Their compact size makes them easy to integrate into a narrow engine compartment. Some variants to be discussed include mechanical interfaces, temperature management or ad-hoc connectors.
