For modern combustion engines, the ever tighter demands on lower emissions and consumption as well as new application areas lead to a considerably complex air path management. Especially the various sizes of throttle valves play a crucial role and with this also the actuators that drive them. Against the backdrop of these challenges, HEINZMANN developed its StG 3 actuator – a new generation of actuators for diesel, gas and dual-fuel engines in mobile and stationary applications.
The development focussed on the following applications: speed, torque and gas flow control of gas and diesel engines; turbo bypass valves for boost pressure control; wastegate valves for boost pressure control; actuators for EGR-control and exhaust gas throttle valves for increasing exhaust gas temperature.
