Definitions
- the invention relates to a supercharged internal combustion engine with a compressor arranged in the intake path.
- the invention further relates to a slider-controlled screw rotor machine which can be used in particular for use as a supercharger in an internal combustion engine of the aforementioned type.
- Screw compressors of various types can be used for charging, ie for the pre-compression of the combustion air in an internal combustion engine, including screw rotor machines (hereinafter referred to as screw compressors).
- screw compressors screw rotor machines
- Previously known screw compressors are not readily available for use as superchargers suitable because there are some disadvantages:
- the charger power must be taken from the engine crankshaft in both operating modes.
- the pressure in front of the charger must also be reduced in accordance with the built-in pressure ratio of the charger in order to be able to provide the required suction pressure of the engine after the charger. This reduction in pressure leads to a relatively high power loss, which must be applied by the motor.
- the charger is e.g. bypassed and only switched on in compression mode via a clutch, which requires considerable control and construction work, there is a sudden increase in torque of the engine when the charger is switched on.
- the essence of the invention is the teaching to use the slide provided on the suction side of a screw compressor instead of the throttle valve of conventional suction motors and to actuate it accordingly.
- the screw rotor machine 1 shown in FIGS. 1 to 3 has a screw rib rotor or main rotor 2 and a screw groove rotor or secondary rotor 3, which are arranged axially parallel and intermeshing in the working space of a housing 13 formed by two intersecting circular cylinders.
- the main rotor 2 is driven, and the drive is transmitted to the secondary rotor 3 via the synchronizing gears 10 and 9.
- the secondary rotor 3 it is also possible to drive the secondary rotor 3, and furthermore the synchronizing gear 10, 9 can be omitted and the drive can be transmitted directly from one rotor to the other via the intermeshing rotor flanks.
- the suction port 7 and the pressure port 8 on the other side of the housing open into the working area of the housing 13.
- the working area of the housing is at the end assigned to the suction port through the low-pressure-side working area end wall 12 and the end assigned to the pressure port 8 is closed off by the high-pressure side work space end wall 11.
- the peripheral wall of the working space in the intersection area of the two circular cylinders is formed by an axially displaceably guided slide 4.
- the connection of the suction nozzle 7 to the working space of the housing 13 can be completely closed or more or less released by axially adjusting the slide 4.
- the slide 4 On its front face lying in the closing direction at the front, the slide 4 has a dovetail-like contour, which is indicated by the line 4a in FIG. 2a, and which is adapted to the course of the helical head or ridge lines of two intermeshing main and secondary rotor ribs in the region of the slide opening is.
- the slider 4 must be able to be moved beyond the low-pressure side end wall 12 of the working area until the opening between the suction port 7 created by the frontal gusset of the slider 4 and work space is closed. 2, the position of the end face of the slide 4 is indicated by the broken line 4b when the position is completely closed.
- the low pressure side The end wall 12 of the working space must therefore have a recess or pocket which allows the complete closing movement of the slide 4, while the opening movement of the slide is made possible by a corresponding recess in the high-pressure side end wall 11.
- the slide 4 is automatically pressed into its closed position by a coil spring 5 arranged in its interior. It can be counter to the force of the spring 5 by a pulling device 6, e.g. a Bowden cable, are moved in the opening direction to release the connection of the suction nozzle 7 to the work space more or less, possibly up to the full maximum value.
- a pulling device 6 e.g. a Bowden cable
- Fig. 4 shows schematically the arrangement of a screw rotor machine 1 as a loader in the air intake system leading from the air filter 17 to the cylinder chambers of, for example, a four-cylinder internal combustion engine 20.
- the suction line of the charger 1 coming from the air filter 17 is designated by 18, and the suction line to the internal combustion engine 20 which is acted upon by this is indicated by 19.
- the loader 1 is driven by the crankshaft of the engine 20 via, for example, a belt drive 22. 23 is the exhaust pipe of the internal combustion engine.
- the slide 4 of the loader 1 is controlled via the pulling device 6 by the accelerator pedal 21 of the internal combustion engine 20.
- the work taken up by the compression corresponds to the area hatched in FIG. 2.
- the work recovered by the regulated screw loader thus corresponds to the area between points A-B-C-D in the p-V diagram in FIG. 2.
- the independent closing of the slide 4 when the pulling device 6 is relieved can be achieved according to the schematic illustration in FIG. 7 and the constructive embodiment in FIG. 1 by one or more springs 5 which act against the pulling device 6, e.g. can be designed as a Bowden cable, work.
- a hydraulic return system according to the schematic illustration in Fig. 8 can also be used, the slide return e.g. by increasing the pressure of the oil in the slide.
- the pulling device can also be omitted if the slide 4 can be moved in both directions (opening or closing) via the electric motor, which is regulated, for example, as a function of the accelerator pedal position of a vehicle.
- the torque between the main rotor 2 and the secondary rotor 3 can be transmitted either via the synchronization gear 9, 10 or via the profile area of the rotors of the screw loader in order to achieve a shorter construction.
- the internal combustion engine 20 shown schematically in FIG. 4 is preferably a diesel engine or a gasoline engine with injection, so that the charger 1 compresses only the intake air.
- the screw designed according to the invention use pressor as a supercharger in a carburetor engine in such a way that it pre-compresses the mixture coming from the carburetor.
- the supercharger 1 is continuously driven by the crankshaft of the engine 20 via the transmission 22.
