Abstract: A device for heating liquids, has a frame in which a container for receiving a liquid medium is arranged, wherein at least some sections of the container are formed of a current-conducting material. The device includes an induction unit generating a magnetic field. The induction unit is arranged outside the container such that it applies a magnetic field to at least one outside wall of the container. At least one section of the container is formed of a composite material, wherein one of the components contains aluminum and the second component contains a material different from aluminum.

Abstract: An arrangement for open-loop control or closed-loop control of a diesel internal combustion engine is described wherein the course of injection is electronically open-loop controllable and/or closed-loop controllable. For this purpose, a metering valve is multiply clocked for each metering cycle. In this way, the course of injection can be formed within wide limits in any desired manner. Furthermore, the unit chamber pressure can be controlled.
