Abstract

Die vorliegende Erfindung betrifft eine turboaufgeladene Hubkolbenkraftmaschine mit mehreren zylindrischen Brennkammern sowie ein Verfahren zum Betrieb derselben, welche je mindestens ein Einlassventil (10), ein Auslassventil (13) und mindestens ein zusätzliches Ladeventil (11) zur zusätzlichen Zufuhr von Druckluft zur Überbrückung des Turbolochs besitzen. Alle Ventile sind über Nockenwellen mit der Kurbelwelle (25) verbunden, wobei die Verbindung der Ladeventile zur Kurbelwelle deaktiviert werden kann, so dass diese Ladeventile geschlossen bleiben. Die richtige Dosierung der Luft für ein stöchiometrisches oder nahezu stöchiometrisches Verbrennungsgemisch wird zusätzlich durch einen Turbolader (4) und eine Drosselklappe (8) erreicht. Durch Verschiebung des Öffnungszeitpunkts der Ladeventile kann Luft von den zylindrischen Brennkammern in den Drucklufttank (14) gepumpt werden, statt solche aus diesen zu entnehmen. Ferner kann ein zusätzlicher Kompressor (24), angetrieben durch die Kurbelwelle (25), ebenfalls Luft in den Drucklufttank (14) befördern.The present invention relates to a turbo-charged reciprocating piston engine having a plurality of cylindrical combustion chambers and a method for operating the same, each having at least one inlet valve (10), an outlet valve (13) and at least one additional charging valve (11) for additional supply of compressed air to bridge the turbo lag , All valves are connected via camshafts with the crankshaft (25), whereby the connection of the charging valves to the crankshaft can be deactivated, so that these charging valves remain closed. The correct metering of air for a stoichiometric or near-stoichiometric combustion mixture is additionally achieved by a turbocharger (4) and a throttle valve (8). By shifting the opening timing of the charging valves, air can be pumped from the cylindrical combustion chambers into the compressed air tank (14), instead of taking them out of them. Further, an additional compressor (24) driven by the crankshaft (25) may also convey air into the compressed air tank (14).
