An important development goal in motor engineering is the improvement of torque and responsiveness.MANN+HUMMEL is striving to achieve this goal by pursuing an innovative impulse charging concept that intensifies the gas dynamics processes at the charge cycle and allows an additional degree of freedom in the valve timing. A substantial increase can be achieved in the frequently used range from 1000 to 3000 rpm.The aim of the project is to develop a fast-moving flap for an intake manifold. In this project, the flap itself is being developed by MANN+HUMMEL together with an OEM, and an actuator is being developed by MANN+HUMMEL alone. The flap actuates in the same cycle as the intake valve. This results in a higher torque at lower rpm levels and no power loss at higher rpm levels.Possible applications are gasoline / diesel engines with / without superchargers, and DI / MPI engines with an increase in torque or compensation for turbo lag.This presentation shows the development of the actuator, the requirements and first results achieved with an actuator prototype and a prototype flap
