Engine Actuators
It’s all in the mix
The valve angle is monitored by throttle electronics, which remain in constant communication with the engine management system.
Overview
Our engine actuator products maximise the potential of modern engine management, offering consistency and good performance. Before fuel can release its energy, it must be combined with air. The resulting mix can then be ignited by using a carefully timed high-voltage spark.
Electromotive Throttle Valves
The valve angle is monitored by throttle electronics, which remain in constant communication with the engine management system. The resulting data is compared in real-time. The optimum throttle position is calculated by the engine management system with regard to both fuel economy and emissions. The information is then fed back to the throttle electronics, which adjust the throttle angle accordingly.

Electronic Throttle Valves
The engine management system compares the position of the accelerator with other on-board sensor data. The optimum throttle angle is then calculated based on current engine conditions. This data is sent to the throttle and the valve is positioned accordingly, i.e. the throttle is controlled solely by means of an electronic signal from the engine management system. Key benefits include improved efficiency under all load conditions.

Idle-Speed Controllers
Idle-speed controllers provide dynamic adjustment of airflow in the throttle bypass valve, ensuring optimal idling at all times. Working in conjunction with the corresponding sensors and an electronic control unit, these devices provide a rapid response to any variation in idle speed.

Digital Linear Actuators
Digital linear actuators provide incremental adjustment of airflow in the throttle bypass valve, ensuring optimal idling at all times. These devices provide a quick response to any variation in idle speed, working in conjunction with the corresponding sensors.

Air control valves
In the intake system of diesel engines, our ACVs (with or without integrated control electronics) use an electric motor to restrict the intake air so that a precisely controlled exhaust gas recirculation system is possible (stricter exhaust standards) and to remedy the annoying shake that occurs when shutting down diesel engines.

Air flap actuators
The electric actuator with integrated position sensor and optional integrated electronics allows intake manifold throttles or turbo charge guide vanes for example to be continuously adjusted. Its more precise control means that it is taking the place of standard pneumatic drives which can no longer satisfy the more stringent requirements.

Exhaust gas recirculation valves
Compared with traditional valves, the electrically actu-ated exhaust recirculation valves enable even more accurate control of the exhaust recirculation rates in Diesel engines and directinjection gasoline engines. This way they make an important contribution towards meeting ever stricter exhaust emission standards.
