Description
Technical field
The present invention relates to engine art, particularly a kind of engine power turbine power recovering device.
Background technique
Available engine power turbine energy recycle device mainly comprises power turbine and clutch mechanism, and power turbine is mechanical work drives external loading turbomachine by clutch mechanism by engine exhaust Conversion of Energy.Power turbine is arranged on turbosupercharger rear portion, connects with turbosupercharger.First engine exhaust passes through turbosupercharger, part discarded energy is recycled by turbosupercharger, the turbine end that remaining exhaust energy enters power turbine, the rotation of promotion turbine, turbine rotarily drive the clutch mechanism work engaging with crankshaft gear, promote crankshaft rotating output power.
But in the time that exhaust energy utilization ratio is low, clutch mechanism keeps separated state, causes the output work that power turbine can not be bent axle by engine exhaust Conversion of Energy; While only having exhaust energy utilization ratio high, this clutch just engages, the output work that power turbine could be bent axle by engine exhaust Conversion of Energy, therefore, engine power turbine power recovering device only Part load just work and frictional loss large, cause exhaust energy utilization ratio low, and this engine power turbine power recovering device complex structure, parts are many, and cost is high, in addition because clutch mechanism weight is large, be unfavorable for the lightweight of motor.
Summary of the invention
The present invention is in order to overcome defect in above-mentioned prior art, provides a kind of simple and reasonable, and exhaust energy utilization ratio is high, and cost is low, and is beneficial to the light-weighted engine power turbine power of motor recovering device.
For achieving the above object, according to the invention provides a kind of engine power turbine power recovering device, comprising: the first turbine and generator, the first turbine is connected on turbosupercharger rear portion, and be connected the generator power supply that is connected with motor storage battery or circuitry with generator drive.
In technique scheme, turbosupercharger comprises: the second turbine and gas compressor.
In technique scheme, the inlet air after gas compressor supercharging enters combustion system of engine and fuel mix burning after intercooler is cooling.
Compared with prior art, the present invention has following beneficial effect: this engine power turbine power recovering device adopts the power turbine with generator, power turbine directly drives generator generating, the electric energy that generator sends can be stored in storage battery, also can be directly used in the circuitry on motor or car load, omit complicated clutch mechanism, make this engine power turbine power recovering device simple and reasonable, exhaust energy utilization ratio is high, cost is low, and is beneficial to motor lightweight.

Embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technological scheme of the present invention.
Engine power turbine power recovering device of the present invention adopts the power turbine with generator, power turbine directly drives generator generating, the electric energy that generator sends can be stored in storage battery, also can be directly used in the circuitry on motor or car load, omitted complicated clutch mechanism, made this engine power turbine power recovering device simple and reasonable, exhaust energy utilization ratio is high, cost is low, and is beneficial to motor lightweight.
As shown in Figure 1, the concrete structure of this engine power turbine power recovering device comprises: turbine 1 and generator 2, and turbine 1 drives and is connected with generator 2, and the exhaust energy of motor 3 enters the turbine end of turbine 1, the rotation of promotion turbine, turbine drives generator 2 to generate electricity again.
Turbine 1 is arranged on turbocharger of motor rear portion, connects with turbosupercharger.Turbosupercharger is actually a kind of air compressor, increases air inflow by pressurized air, mainly comprises: turbine 4 and gas compressor 5.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the turbine 4 in turbine chamber, then drives the inlet air of gas compressor 5 compression engines, makes it to enter combustion system of engine after cooling by intercooler 6 after supercharging and burns with fuel mix.When engine speed speeds, the waste gas velocity of discharge is also synchronizeed and is speeded with secondary speed, gas compressor 5 just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, the rotating speed of corresponding increase fuel quantity and adjustment motor, just can increase the output power of motor.
Motor 3 waste gas are after the turbine 4 of turbosupercharger, part exhaust energy is recycled by turbosupercharger, the turbine end that remaining exhaust energy enters turbine 1, the rotation of promotion turbine, the generator 2 that rotarily drives of turbine generates electricity, generator 2 is connected with the turbine of power turbine and is connected with the circuitry on storage battery or motor and car load, and the electric energy that generator 2 sends can be stored in storage battery, also can be directly used in the circuitry on motor or car load.Owing to adopting a generator to replace the clutch mechanism of original complexity, this engine power turbine power recovering device is simple in structure, and parts are few, and cost is low.As long as diesel engine operation, generator just can be worked, and modern generator is converted to mechanical energy the efficiency of electric energy up to more than 99%, compares the high rotating speed operating mode work of only having of clutch and mechanical loss and is no less than 10% shortcoming, and exhaust energy utilization ratio is higher; Generator is lighter than clutch configuration, uses and more meets light-weighted demand with the power turbine energy recycle device of generator.
To sum up, this engine power turbine power recovering device adopts the power turbine with generator, power turbine directly drives generator generating, the electric energy that generator sends can be stored in storage battery, also can be directly used in the circuitry on motor or car load, has omitted complicated clutch mechanism, make this engine power turbine power recovering device simple and reasonable, exhaust energy utilization ratio is high, and cost is low, and is beneficial to motor lightweight.
