Embodiment
Accompanying drawing discloses the structural representation of preferred embodiment involved in the present invention without limitation; Below will combine accompanying drawing that technological scheme of the present invention at length is described.
As shown in Figure 1, petrolic used heat according to the invention utilizes the combined type supercharging device again, comprises exhaust gas turbocharge device, mechanical pressurizing apparatus and the used heat supercharging circulation means that walks abreast and be provided with the exhaust gas turbocharge device; Said mechanical pressurizing apparatus is in series through magnetic clutch 16 and exhaust gas turbocharge device, used heat supercharging circulation means respectively; Said used heat supercharging circulation means comprises that used heat absorbs re-use device 7, steam intensifier 9 and one-level pressurized machine 12; Said exhaust gas turbocharge device comprises exhaust-gas turbocharger 2 and two-stage supercharger 15; It is heat exchanger that said used heat absorbs re-use device 7; The hot-side channel import of this heat exchanger is connected with petrolic radiator 6; And import low-temperature receiver in the cold side passage of heat exchanger; Said low-temperature receiver is critical water-low-pressure water steam mixture in evaporation; And the cold side channel outlet of heat exchanger is connected with the suction port of steam intensifier 9, and the clutch end of steam intensifier 9 is rigidly connected with one-level pressurized machine 12 through the first supercharging rotating shaft 10, and the relief opening of steam intensifier 9 is communicated with the cold side channel entrance of heat exchanger through the exhaust cycle pipe; And air pressure controlled adjuster 5 is installed on this exhaust cycle pipe, and this air pressure controlled adjuster 5 comprises the valve that is used to detect the pressure transducer of exhaust cycle intraductal atmospheric pressure and controls keying according to pressure transducer institute feedback pressure value automatically; Said exhaust gas turbocharge device comprises exhaust-gas turbocharger 2 and two-stage supercharger 15; The suction port of exhaust-gas turbocharger 2 is connected with petrolic waste gas row mouth through waste gas pipeline 1, and the clutch end of exhaust-gas turbocharger 2 is rigidly connected through the second supercharging rotating shaft and two-stage supercharger 15; One-level pressurized machine 12 is communicated with source of the gas through super charge pipe 11, and two-stage supercharger 15 is connected with one-level pressurized machine 12 through connectivity trachea 13, and the relief opening of two-stage supercharger 15 is connected with petrolic oil cylinder through engine air inlet tube 18 simultaneously.
Among the present invention; Said steam intensifier 9, one-level pressurized machine 12, exhaust-gas turbocharger 2, two-stage supercharger 15 include chamber and are installed in the impeller mechanism in the chamber; Wherein, Impeller mechanism in steam intensifier 9, the exhaust-gas turbocharger 2 is a turbine mechanism, and the impeller mechanism in one-level pressurized machine 12, the two-stage supercharger 15 then is a pump impeller mechanism.The pto of said mechanical pressurizing apparatus and the coaxial setting of the second supercharging rotating shaft, and magnetic clutch 16 is installed between the pto of mechanical pressurizing apparatus and the second supercharging rotating shaft; And the pto of mechanical pressurizing apparatus is connected with the first supercharging rotating shaft 10 through universal driving device 14, and between the pto of this universal driving device 14 and mechanical pressurizing apparatus another magnetic clutch 16 is installed.
The waste gas that the present invention discharges during through engine operation promotes the turbine rotation in the exhaust-gas turbocharger 2, rotates and carries out two-stage supercharging, i.e. EGR thereby drive pump impellers in the two-stage supercharger 15.Mechanical pressurizing apparatus when work, rotate through the turbines that transmission device drives in the mechanical supercharger 17 by the bent axle of motor, rotate with pump impellers in the two-stage supercharger 15 and carry out supercharging thereby drive one-level pressurized machine 12.Wherein, Used heat supercharging circulation means is connected for parallel with the exhaust gas turbocharge device; Used heat supercharging circulation means is connected with mechanical pressurizing apparatus through magnetic clutch 16 through universal driving device 14 and exhaust gas turbocharge device again together simultaneously, thereby forms the combined type pressurization system on the whole.
In this process of the little load condition of vehicle starting to low speed; Because the EGT (energy) that engine radiator 6 temperature are not high and automobile tail is discharged is not high yet,, can make engine booster sluggish so used heat supercharging circulation means and turbo charge system all do not have good pressurized effect; So in time, should combine through magnetic clutch 16 control transmission shafts; Make mechanical supercharger 17 performance pressurizations, the gas that suction tude is got into carries out I and II supercharging work, improves engine power.
In the big load operation state of automobile (in) at a high speed (in); Because effects such as friction can make the lifting of mechanical supercharger 17 limiting engine rotating speeds and the raising of power; So should control magnetic clutch 16 this moment transmission shaft is separated; Thereby make used heat supercharging circulation means play the one-level pressurization, exhaust-gas turbocharging system plays the two-stage supercharging effect.Improve through air inflow behind the two-step supercharging, and then improved engine power.
The gas pressure of low-temperature receiver (water vapour exhaust cycle pipe 4 places) originally is lower than the pressure that used heat absorbs re-use device 7, water vapour air inlet Circulation pipe 8 places, but when gather a certain amount of after, it is big that air pressure also can become gradually; The valve open of air pressure controlled adjuster 5 then, gas get into used heat and absorb re-use device 7, and used heat absorbs re-use device 7 place's temperature because conduction of heat; Influenced by radiator 6, approximate identical with radiator 6 temperature, temperature is higher; Because this moment, gas temperature will be lower than used heat absorption re-use device 7 place's temperature; So when gases are heated, they expand, pressure increases, and then drives rotating shaft rotation supercharging through pressure reduction; Because heat can preferentially transmit to the temperature lower, radiator 6 ambient air temperatures are generally higher, so the thermal-arrest operation is not essential, just under the situation that the thermal-arrest operation is arranged, utilization ratio is higher.Here with thermal-protective material radiator 6 and used heat re-use device 7 are encapsulated in a confined space, heat loss is just fewer like this.
