Definitions
- the invention relates to a quantity-controlled internal combustion engine with the features of the preamble of patent claim 1.
- a device for charging an internal combustion engine is known, in particular a four-stroke gasoline engine whose inlet side is supplied from an upstream, with the outlet side of the engine operatively connected to the pressure booster (supercharger system) lying above the atmospheric pressure boost pressure.
- 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 internal combustion engine 1 has at least two cylinders 2 arranged in a row, whose longitudinal axes 2 'span a plane perpendicular to the plane of the drawing of an internal combustion engine longitudinal axis.
- the engine longitudinal axis also corresponds to the extension direction of a crankshaft, not shown.
- the internal combustion engine 1 may also have only one or more cylinders 2 arranged in series.
- a fuel introduction, not shown, can take place in an intake system 3 and / or directly into the cylinder 2, wherein in the intake system 3 as a load control member a Trochoidenmaschine 4 is arranged with a rotary piston 5.
- 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
- the rotary piston 5 describes a planetary motion and rotates at half the speed of rotation about its rotary piston axis 5 ', which in turn rotates with shaft speed and rotationally fixed, for example, with a crankshaft, not shown, of the internal combustion engine or a separate electric machine is coupled. By this rotation, an intake air is compressed or expanded, wherein the amount of air via the rotary valve 11 is adjustable.
- An air flow direction is indicated by thick arrows, in FIG Fig. 1 ie after an axial inflow (perpendicular to the plane of the drawing) radially into the Trochoidenmaschine 4.
- An ignition device for the internal combustion engine 1 is numbered 14.
- a remindströmsperrelement 12 is arranged in the flow direction of the intake after Ansaugluftabriosö réelle 9 in the intake system 3, which may be a flap in the simplest case or controlled or regulated flap mechanisms.
- this remindströmsperrelement 12 also serves as a check valve.
- the intake air in the flow direction in front of the Ansaug Kunststoffzu Kunststoffö réelle 8 can also be heated by an exhaust gas of the internal combustion engine 1 in a heat exchanger.
- the trochoid machine 4 extends in the axial direction across the width of at least one cylinder 2.
- the outer diameter of the trochoid machine can be significantly reduced, which benefits the design, or the package again.
- Fig. 2 schematically shows an inflow A for the intake air over time (or the angle of rotation of the rotary valve 11) in the Trochoidenmaschine 4.
- the line is shown in solid lines and a large load and / or speed, the line is shown in dashed lines.
- a load control according to the invention for the quantity-controlled internal combustion engine 1 is proposed, in which the troubleshooting machine 4, a rotary piston machine, is used as the expander or compressor of the intake air, the throttle-free inlet (essentially over the length of the opening period, see Figure 2) is regulated.
- the Trochoidenmaschine 4 is mechanically coupled to the internal combustion engine 1 or a drive train to those of the z in the partial load. B. from 1 bar to 0.3 bar expanded fresh gases work done decrease.
- the intake air supply opening 8 can also be charged with the internal combustion engine 1 (assuming energy intake from the drive train) with a correspondingly wide inlet cross section become.
- Fig. 1 an exemplary, possible arrangement is shown:
- the matching envelope is also a trochoid in this simple case, namely a subsection of a suitably elongated epitrochoid.
- the degree of slimming is a freely selectable parameter, corresponding to the shortening or lengthening of the trochoid.
- the current position is represented by a solid line, the three further rotated possible positions are shown in dashed lines.
- a black arrow indicates the direction of rotation of the rotary piston 5.
- the inlet control is carried out from radially via a rotating rotary valve, with adjustable cover slide (double arrow), being flowed in the axial direction in the cylindrical or conical rotating rotary valve to be considered.
- a quiescent, coolable seal 10 can be easily attached.
- the proposed geometry is characterized by particularly high air flow in terms of space (only one runner, no inner and outer rotor and housing) and small harmful piston surfaces in cross-section in comparison to higher trochoid.
- the radial inflow of the intake air fits perfectly to the space of a series internal combustion engine, as in the overall length (across the plane) scalable.
- Trochoid machines 4 can be shown with suitable geometry in hot gas material (ceramic o. ⁇ ) with gap seals at the peripheral sealing point and thus allow the use of exhaust heat.
