Description
Technical field
The present invention relates to the supercharging air method and the device of a kind of raising and controlling combustion engine gas handling system airspeed and flow, belong to the core system device of air-intake of combustion engine boosting method.
Background technique
Up to now, more, well-known for the method that improves air-intake of combustion engine speed and flow, the work of motor car engine all is to do work at the engine air in-cylinder combustion by fuel, thus externally output power, torque.Under the certain condition of engine displacement, if the output power and the torque of wanting to improve motor, effective method provides fuel combustion exactly.Yet, in cylinder, provide fuel to accomplish easily, but the air that q.s will be provided only depends on the natural aspiration mode of conventional engines and air-flow motion mode to finish to support fuel perfect combustion more.Therefore, how to improve ability that motor the sucks air particular importance that just seems.
Supercharging technology is exactly a kind of raising engine charge effective methods, and exhaust gas turbine is one of method of air intake pressurized, but the exhaust gas turbocharge method and apparatus still has the following disadvantages and defective:
The power that drives the turbine rotation is the 700 degree high-temp waste gas that motor is discharged, in order to improve the turbine rotation efficiency, the design accuracy height of turbine, complex process, floating axle is again to turn round under the harsh harsh conditions of High Temperature And Velocity, the lubricant oil of floating axle continues to be under the high temperature condition, easily gum deposit matter and stop up oil duct causes for want of lubricated generation of floating axle not float and axis.Therefore, the reliability of this device and poor durability, this stuck major defect of floating axle are still a difficulty that is difficult to overcome that faces in the design of exhaust gas turbocharge in the world, production and the application so far.
The exhaust gas turbocharge device volume is big and weigh, also is subjected to the difficulty of engine nacelle layout and thermal radiation, the transmission of heat influence to surrounding environment simultaneously, causes other main parts size to improve resistance to heat again and difficult.The required air inflow of gas compressor that exhaust gas turbine drove when this device also existed the slow-speed of revolution of motor place, acceleration and motor real-time working condition can't be mated.The engine exhaust energy that its reason is all got owing to the power of gas compressor fan blade, and in the synchronization of motor, linear.Therefore, using this kind principle and method air is carried out the air pressure and the flow velocity of the pressurized air that supercharging produced, is to link with corresponding exhaust pressure of the rotating speed of motor and power transmission shaft change in rotational speed to change.
And the speed range of motor car engine is very wide, is in operation, and the operating mode of moment and rotation speed change can't provide suitable, stable pressurized air stream.Yet the synchronization of pressurized machine sharply rises when the high rotating speed in motor place, makes overpressure.Although adopt vacuum valve, solenoid valve with bypass mode exhaust pressure limiting when anxious acceleration, high rotating speed, this kind regulation and control lag behind all the time, cause oil supply system correctly quantitatively to mate, and cause the imbalance of supercharging air fuel ratio, burn deterioration, power decline, blowdown to increase.
In addition then, traditional exhaust-gas turbocharger is because transmission of heat and high rotating speed supercharging, the air that makes supercharging be heated and expand, density is low, reduced air inflow, must resupply intake duct after another intercooler unit cooling.At this moment, because vapour lock increases, have a strong impact on charge air flow speed, in order to drive the exhaust gas turbine high speed rotating, motor has increased exhaust back pressure, makes cost with the energy and the power of a working stroke in the direct loss.Moreover the engine exhaust back pressure is too high, causes exhaust unclean, has directly influenced air charge coefficient and air inlet ability.Package unit is subjected to the restriction of its principle, structure, makes system complex, and the cabin is difficult to arrange, installation is difficult, workload is huge, matching is poor, the expense costliness.
In order to solve this technology barrier, the international monopoly PCT/US97/12477 (international publication number WO98/02652) of California, USA Turbodyne Systems Inc application discloses a kind of turbo charging installation that uses with internal-combustion engine, see also Fig. 1, he comprises improved and the electric rotating machine member, and provides a kind of improved exhaust gas turbine and compressor apparatus to improve the performance of exhaust gas turbine gas compressor boosting internal combustion engine.This improved exhaust gas turbine 10, gas compressor 61, comprise some magnet 12, they are installed in the roughly circumference range of compressor impeller 13 back peripheries.One stator winding 14 is installed in motor magnet and becomes opposed relationship.When stator is excitatory by suitable exciting circuit, can be to the magnet effect, thereby can apply moment to compressor impeller, thereby, especially when low engine speed, improved the performance of motor.
The technological scheme of this invention is intended to adopt waste gas power and external electric energy to drive a gas compressor job with the supercharging of exciting electric motor speedup, overcome that exhaust gas turbine is subjected to low engine speed, the shortcoming of the air demand deficiency of the gas compressor that restriction causes of exhaust energy when quickening, a kind of positive technological scheme of taking for the needs that satisfy the engine booster air inflow.
Yet, reason owing to its structural design, electric motor is built among exhaust gas turbine and the gas compressor, make the magnet and the electromagnetic wire isolation layer of motor be under hyperthermia radiation and the heat conducting influence, temperature rise when the surrounding environment basal temperature is superimposed with machine operation, the magnet that causes motor surpasses curie temperature and loss of excitation is difficult to bear proper functioning under this environment.Even take cooling scheme, because too near and of no avail apart from the high exhaust temperatures source.
