  • This device for charging is characterized in that the loader is a modified rotary piston machine (Trochoidenmaschine), the input side as a compression machine and at the same output side, each related to the internal combustion engine, works as an expansion machine, the rotary piston machine for their compression range and for their expansion range on each separate Has inlet and outlet openings and wherein the rotary piston machine is rotatably connected to the internal combustion engine.
  • the rotary piston machine is arranged on the front side of the internal combustion engine, resulting in disadvantageously relatively long ways for the intake air or for the exhaust gas.
  • German patent application DE 101 16 264 A1 a method for operating an internal combustion engine, with a arranged in the intake tract mechanical compressor, which is drivable via a coupling device via the crankshaft.
  • combustion air is delivered to an engine intake.
  • a device for the variable adjustment of the compression ratio in the combustion chamber is provided, via which a higher compression ratio can be set in the partial load range of the internal combustion engine and a lower compression ratio in the full load range.
  • the air mass flow to be delivered by the compressor is variably adjustable, being operated in the partial load range below a reference load value of the compressor for adjusting a negative pressure in the air inlet throttle or expander operation.
  • German patent application DE 10 2009 028 086 A1 a rotary piston machine and a charging device known. It is a rotary piston machine with a housing having a chamber in which at least one rotary piston is eccentrically rotatably mounted, which divides the chamber into a first sub-chamber and a second sub-chamber. It is provided that the outer contour of the rotary piston - seen in cross section - is a double-lobed hypotrochoid. Furthermore, such a charging device, in particular for the operation of an internal combustion engine or a fuel cell assembly is described.
  • This charging device is realized with two rotary piston machines.
  • the first rotary piston machine is used in the illustrated example as a compressor and the second rotary piston machine as an expander.
  • the DE 10 2009 028 086 A1 thus discloses a rotary piston machine with which a fluid is compressible or expandable.
  • Object of the present invention is to show a total geometry for a generic internal combustion engine, which works efficiently and compact builds.
  • the intake air amount can be regulated in an advantageous manner, so that the internal combustion engine via a very wide speed and / or load band is operable.
  • the intake air can thus be advantageously expanded (diluted for low load) or compressed (compressed for high load, charge case).
  • this configuration serves as a check valve in the case of charging.
  • the outer radius of the trochoid machine can be significantly reduced, whereby the space is reduced again.
  • Fig. 1 schematically shows a variable-volume internal combustion engine 1 according to the invention, in the present case, a four-stroke reciprocating internal combustion engine.

  • the load is the load on an internal combustion engine between zero load (for example, idle) over the partial load to full load and also the shift operation.
  • the desired load (load control, load control) is set in the conventional gasoline engine by the mixture mass (quantity control or fuel / air mass flow rate control).
  • the mixture mass in turn is specified by a control element.
  • the control member is usually a throttle flap, in the present case according to the invention, the trochoidal machine 4 in conjunction with a rotary valve 11th
