Description
Technical field
The present invention relates to a kind of turbo charge system, in particular to a kind of exhaust gas turbine and the integrated turbine of electric turbine
Pressure charging system can deploy energy flow direction according to secondary speed.
Background technique
Turbocharging technology is the means for promoting engine power.It is different from the maximum feature of naturally aspirated engine, is
With one group of turbocharger, it is used to change the Air intake characteristics of engine.
Currently, any automobile engine all includes air-breathing, compress, acting is vented four circulation steps.Natural aspiration starts
The air inlet power of machine is generally viewed as 1 atmospheric pressure entirely from the machinery inertial after work by combustion.And turbocharged engine
Machine has installed coaxially arranged turbine and compressor additional among exhaust system and gas handling system.When the engine is working, exhaust is dynamic
Dynamic exhaust gas turbine is pushed, the compressor for being connected to gas handling system starts simultaneously at rotation, and air is pressed into cylinder, this leads to same feelings
Under condition, the air pressure in cylinder is got higher, more than 1 atmospheric pressure.It is that the oxygen content in unit volume is promoted that air pressure, which promotes bring,
It allows for burning up more fuel in acting link, it is final to promote power performance.It is identical using the engine of turbocharging technology
The engine size of power becomes smaller, and the engine power of same displacement becomes larger.
But when engine speed is lower, the exhaust gas of engine discharge is not enough to drive exhaust gas turbine, even if can drive
Dynamic exhaust gas turbine, the boost pressure provided are also very limited.In order to solve this problem, automobile current generator engineers design
Electric turbine, when engine is compared with the slow-speed of revolution, exhaust gas turbine and electric turbine are worked together, to improve engine power output water
Flat, in higher engine speeds, the exhaust gas of engine discharge is enough to drive exhaust gas turbine, and exhaust gas turbine works independently at this time,
Electric turbine stops operating, to save electric energy.For this reason, it may be necessary to increase a turbine, such design in turbo charge system
The manufacturing cost of engine can be obviously increased, therefore electric turbine is often luxury car configuration.
Whether traditional exhaust gas turbine or emerging electric turbine, main purpose are to improve the power of engine
(i.e. power), only in the case where design conditions and proper power matching, turbocharging has certain castering action to the thermal efficiency,
Its design conditions is often high speed conditions, but most of passenger car not runs on the operating condition in the most of the time, this is just
Turbo charged actual efficiency is caused to show as higher oil consumption lower than natural aspiration.
With the development of society, fuel economy and the feature of environmental protection are increasingly emphasized in the design of automobile engine.For this this hair
It is bright to propose a kind of hybrid power turbo charge system, to a certain extent the drawbacks of solution conventional turbine pressure charging system.In height
Under revolving speed, exhaust energy is bigger, and compressor can produce very big boost pressure, in conventional turbine pressure charging system, to guarantee
Turbine safety and service life, the boost pressure more than a threshold value are laid down by turbine exhaust by-passing valve, this portion energy
Amount is wasted.The present invention incorporates the electricity that can be used as generator but also as motor in turbo charge system
Machine, motor maintains boost pressure in suitable range by control generated energy, while can not slattern this parts of traditional again
The energy that turbine is laid down, motor functions as a generator at this time, and at the low rotational speed, the finite energy of exhaust ventilation provides
Boost pressure it is also limited, motor plays a role as motor at this time, drive turbine improve boost pressure, improve turbo lag
Problem.
Summary of the invention
The purpose of the present invention is to provide a kind of hybrid power turbines that energy flow direction can be deployed according to secondary speed
Pressure charging system.
What the present invention is realised by adopting the following technical scheme:
A kind of hybrid power turbo charge system, including internal combustion engine, exhaust gas turbine, compressor, motor and battery；Its
In, when work, exhaust gas turbine by internal combustion engine exhaust gas or motor driven；When exhaust gas flow is larger, exhaust gas turbine drives main shaft high
When speed rotation, motor serves as generator, absorbs the energy of a part of exhaust gas, and there are in battery；When exhaust gas flow is smaller, main
When axis low speed rotation, motor serves as motor, converts mechanical energy for the electric energy in battery to drive compressor, guarantees to calm the anger
The supercharging effect of machine.
A further improvement of the present invention lies in that clutch is installed between motor and exhaust gas turbine, the shaft end of compressor
Speed probe is installed, clutch carries out clutch operation according to the revolving speed size that speed probe measures, and controls in engine
Two control revolving speeds are set in system: height control revolving speed and low control revolving speed；When the revolving speed measured is small greater than low control revolving speed
When height controls revolving speed, clutch is disconnected, and motor does not play a role；When the revolving speed measured is less than low control revolving speed, clutch
It closes, motor plays a role as motor；When the revolving speed measured is greater than high control revolving speed, clutch also closes, and motor is made
It plays a role for generator.
The present invention has following beneficial technical effect:
Hybrid power turbo charge system provided by the invention utilizes the direction of a motor allotment energy flow.In height
Under revolving speed, exhaust energy is bigger, also has extra energy for generating specified boost pressure, at this time with exhaust gas turbine phase
Motor even will function as a generator, this portion of energy is stored in Vehicular accumulator cell.Motor passes through control power generation
Amount can not slattern the energy that this parts of traditional exhaust gas turbine is laid down to maintain boost pressure in suitable range again,
Improve the fuel economy and environment-friendly type of generator.At the low rotational speed, the finite energy of exhaust gas, the boost pressure provided is not
Foot, motor plays a role as motor at this time, drives compressor to improve boost pressure, guarantees the same of engine output
When, so that engine is run near optimum thermal efficiency operating condition.It is asked in addition, the incision of motor can also improve turbo lag
Topic.
Further, clutch is installed between motor and exhaust gas turbine, for motor to be cut or cut out from system, is pressed
The shaft end of mechanism of qi is equipped with speed probe, for measuring the revolving speed of main shaft.Clutch is big according to the revolving speed that fast sensor measures
Small carry out clutch operation, there are two control revolving speed for setting in engine control system: height control revolving speed and low control revolving speed.Two
Section between a control revolving speed is referred to as desired speed section, this section compressor supercharging amount close to optimal pressurization
Amount, engine are run near optimal output power and thermal efficiency operating condition.When the revolving speed measured is between desired speed,
Clutch disconnects, and motor does not play a role；When the revolving speed measured is less than low control revolving speed, clutch closes, and motor is as electricity
Motivation plays a role, with revolving speed continuous improvement and approach low control revolving speed, the excitation voltage of motor gradually decreases, reduce electricity
The power of machine output；When the revolving speed measured is greater than control revolving speed, clutch also closes, and motor functions as a generator,
Constantly reducing and approach high control revolving speed with revolving speed, the excitation voltage of motor is gradually lowered, and reduces the power generation function of motor
Rate.
