Abstract

Ein Lineargenerator für ein Fahrzeug mit einem Verbrennungsraum (3) zwischen zwei einander gegenläufigen Kolben (2a, 2b) in einem Zylinder (1). Die Kolben (2a, 2b) tragen an ihrer Peripherie Permanentmagnete (8) und bewegen sich innerhalb einer Spulenanordnung mit Wicklungskörpern (9a, 9b) hin und her. Der Verbrennungsraum (3) ist mit einer Einspritzdüse (7), einer Zündkerze (6) einem elektrisch angesteuerten Einlassventil (4) und einem elektrisch angesteuerten Auslassventil (5) ausgestattet. Der Aus und Einlasstakt kann, zwecks Temperaturregelung, durch zeitliche Pausen getrennt werden. Die Spulen dieser Spulenanordnung werden mittels einer Regeleinrichtung (14) unter Zuhilfenahme von Positionssensoren (10a, 10b), oder statt diesen mit einer weiteren Recheneinheit die aus der Spulenanordnung die Kolbenposition ermittelt, individuell angesteuert. Die Polteilung der Spulenanordnung und die der Kolbenpole sind, zwecks Geräuschminderung, unterschiedlich ausgeführt. Zur Entlastung des Umrichters (11) sind im Bereich der äußeren Umkehrpunkte der Kolben Luftfedern (15a, 15b) vorgesehen, welche die kinetische Energie der Kolben (2a, 2b) bei der Bewegung nach innen zurück liefern.A linear generator for a vehicle having a combustion chamber (3) between two mutually opposed pistons (2a, 2b) in a cylinder (1). The pistons (2a, 2b) carry on their periphery permanent magnets (8) and move within a coil arrangement with winding bodies (9a, 9b) back and forth. The combustion chamber (3) is equipped with an injection nozzle (7), a spark plug (6) an electrically controlled inlet valve (4) and an electrically controlled outlet valve (5). The off and intake stroke can, for the purpose of temperature control, be separated by time intervals. The coils of this coil arrangement are individually controlled by means of a control device (14) with the aid of position sensors (10a, 10b), or instead of these with a further computing unit which determines the piston position from the coil arrangement. The pole pitch of the coil assembly and the piston poles are designed differently for noise reduction. To relieve the converter (11), air springs (15a, 15b) are provided in the region of the outer points of reversal of the pistons, which return the kinetic energy of the pistons (2a, 2b) to the inside during the movement.
