Abstract
The present invention relates to a turbocharged reciprocating piston engine, and to a method for operating said engine. The combustion chamber includes at least one inlet valve (), one outlet valve () and at least one additional charging valve (), for the additional feed of compressed air to bridge the turbo lag, that are each operatively connected to the crankshaft via a camshaft and the operative connection of the charging valves to the crankshaft can be deactivated, with the result that the at least one charging valve () remains closed. An approximately stoichiometric combustion mixture is achieved by a turbocharger () and a throttle valve (). By displacement of the opening instant of the charging valves (), air can be pumped from the cylindrical combustion chambers into the compressed air tank (). An additional compressor () can likewise deliver air into the compressed air tank ().
