A compressor system and a method for operating a compressor system is provided. The system includes an air compressor and a planetary gear train having an input shaft connected to a planetary carrier of the gear train and an output shaft connected the compressor and a sun gear of the gear train. A first switchable fixing device fixes one of means of which the planet carrier, the sun gear and a ring gear of the gear train with respect to an outer support, and a second switchable fixing device fixes relative to one another the two of components not fixed by the first switchable fixing device of the planetary gear train.

Compressor system and method for operating a compessor system

A process is provided for starting an internal-combustion engine, particularly a Diesel engine, having an exhaust gas turbocharger and an inlet gas supply device with at least one compressed-air reservoir which is connected with an intake pipe of the internal-combustion engine. During the starting of the internal-combustion engine, additional air is blown from the inlet gas supply device into the intake pipe until a rotational speed of the internal-combustion engine reaches a previously definable idling speed.

A fresh gas supply device is provided for an internal combustion engine having a turbocharger. The device includes a charge-air inlet for taking in charge-air from the exhaust gas turbocharger, a compressed air inlet for taking in compressed air, an outlet connectable to the charge-air inlet via a flap element and to the compressed air inlet via a flow regulating device, and a control unit for controlling the flap element and the flow regulating device. The flow regulating device has at least one valve for opening and closing the compressed air inlet and a proportional valve connected downstream in the direction of flow for setting a pressure in the outlet.
