Abstract
The utility model discloses a double-impeller combined turbocharging apparatus which belongs to the turbocharger technology field. The double-impeller combined turbocharger comprises a motor impeller, a motor, a storage battery, and an exhaust gas turbocharger. The double-impeller combined turbocharging apparatus is characterized in that the impeller driven through the motor is added on a conventional exhaust gas turbocharger, wherein the switch of the motor is controlled through an ECU, the motor is automatically turned on through the ECU when the engine is running at a low speed, the electric energy of the motor comes form the storage battery, the motor impeller is driven through the motor to rotate and the air is compressed, and therefore inlet air of the engine is supercharged when the engine is running at a low speed. When the engine runs at a high speed, the exhaust gas turbine is driven through the exhaust gas of the engine to rotate at a high speed, and therefore the exhaust gas impeller is driven to rotate through a supercharger shaft, and the inlet air of the engine is supercharged. Then the engine is turned off through the control of the ECU, the motor impeller rotate passively in the air compressed through the exhaust gas impeller, and therefore the rotor inside the motor is driven to rotate, and electricity is stored in the storage battery through the motor which serves as an electric generator. The supercharger is characterized by improvement in the turbine delay phenomenon of a conventional exhaust gas turbocharger, assisting supercharging system power coming from the storage battery of the supercharger, engine power which is not shared, and energy-saving and high efficiency effects.
Description
Technical field
The utility model relates to the technical field of a turbosupercharger, especially a kind of bilobed wheel composite turbocharging device.
Background technique
Exhaust gas turbocharge is a kind of technology of utilizing internal-combustion engine to operate the exhaust gas driven air compressor that produces, has both utilized combustion gas to drive turbosupercharger, and fresh air is injected in the internal-combustion engine, reaches the horsepower output effect that promotes internal-combustion engine.Turbo charged Main Function improves air input of engine by air exactly, thereby improves power and the moment of torsion of motor.After a motor was loaded onto turbosupercharger, its peak output is compared when being unkitted pressurized machine can increase by 40% even higher.Just meaning that so also same one motor can produce larger power through after the supercharging, is exactly to improve fuel economy and reduce exhaust emissions in addition.
Traditional exhaust-gas turbocharger critical piece is exhaust gas turbine, and pressurized machine axle, waste gas impeller are done, and can not drive simultaneously turbo driving when motor just starts, can make motor the start up period produce the deficiency of having an effect and be turbo lag; Turbo lag is large to indicate that it may have an effect suddenly, will be difficult to grasp for usual driving, drive difficulty even potential safety hazard is arranged, on the impact in working life of supercharging device itself greatly, increase regular maintenance and maintenance cost.
Thus, the inventor considers traditional supercharging device is improved, and this case produces thus.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, convenient to use, pressurized effect is good, long service life, efficient is higher and cost is low bilobed wheel composite turbocharging device.
For achieving the above object, the utility model is achieved through the following technical solutions:
Bilobed wheel composite turbocharging device comprises electric motor with vane wheel, motor, storage battery and exhaust-gas turbocharger; Described electric motor with vane wheel is located between exhaust-gas turbocharger and the motor, and described motor one end is connected with storage battery, and this motor is by the ECU control switch,
Exhaust-gas turbocharger described above mainly comprises spiral case and the exhaust gas turbine, pressurized machine axle and the waste gas impeller that connect successively.
Electric motor with vane wheel described above is connected with motor, this electric motor with vane wheel when the motor slow-speed of revolution by motor driving rotation and motor is entered gas carry out supercharging, this electric motor with vane wheel when the high rotating speed of motor by air driven and the drive motor generating of exhaust gas turbine compression.
Motor described above is a kind of multi-rotor motor-driven, power generation all-in-one machine, its power resources are in storage battery, when motor is in high rotating speed, and the passive rotation in the air of waste gas impeller compression of electric motor with vane wheel this moment, thereby the rotation of drive motor internal rotor, motor transfers generator to storage battery is carried out electric power storage.
Advantage of the present utility model:
The inventor has increased by one by motor-driven electric motor with vane wheel at traditional exhaust-gas turbocharger, motor is by the ECU control switch, by the ECU(vehicle-mounted computer) at low engine speed state control motor driving electric motor with vane wheel motor is entered gas and carry out supercharging, when motor reaches high rotating speed, the waste gas impeller that is driven by exhaust gas turbine enters the gas supercharging to motor, simultaneously, waste gas impeller compressed air-driven electric motor with vane wheel rotates, thereby the drive motor rotor makes electric power generation, to the storage battery electric power storage.This pressurized machine has improved the defective of conventional turbine pressurized machine supercharging deficiency when low engine speed, take full advantage of exhaust energy, and do not share the power of motor, not only solved the turbo lag phenomenon, and has certain energy-conserving action, have suitable Practical significance and market value, reach the purpose of motor being carried out supercharging.
