Description
Technical field
Invention relates to automobile-used variable nozzle turbocharger technical field, is specifically related to a kind of variable nozzle turbocharger controlling mechanism that is integrated on the turbine shroud.
Background technique
Internal-combustion engine develops into more than 100 year later today from invention, and correlation technique is constantly brought forth new ideas and moved to maturity.But internal-combustion engine still faces problems as automobile power: the thermal efficiency not high (particularly petrol engine); The petroleum resources that rely on reduce gradually; The pollution from exhaust emission atmosphere environment, and be difficult to concentrate improvement etc.Engine booster mainly improves density of the induced air by gas compressor, and this technology is used widely as the important measures that improve HP, hp/litre, improve Economy and emission performance.According to the difference that drives the gas compressor mode, engine booster can be divided into engine driven supercharging, complex supercharge and three kinds of basic modes of exhaust gas turbocharge.
The waste gas with certain energy that motor is discharged in exhaust gas turbocharge is introduced turbine and the acting of expanding, whole power of exhaust gas turbine are used for the gas compressor running wheel of driving and turbo machine coaxial rotating, will send into cylinder after the compresses fresh air in gas compressor again.Exhaust gas turbocharge has improved the export ratio of useful horsepower owing to having utilized exhaust energy, therefore the motor Economy obviously improves, and can reduce significantly discharging and the noise level of harmful gas.
Vehicular engine is motive power machine device, output high torque (HT) when requiring low speed.For exhaust gas turbocharge, because turbo machine is fluid machinery, its boosting capability depends on the rotating speed of pressurized machine.The raising of supercharger speed is to promote vane rotary by the energy that the waste gas that motor is discharged has at turbo machine to obtain.During low engine speed, the little and energy shortage of extraction flow, secondary speed is low to cause the pressurized effect of gas compressor not obvious, and engine torque increases few, the mutual contradiction of engine torque characteristic that requires with vehicle.Internal-combustion engine is to the rapid response of load with rotating speed, and is very important to Security and the Economy of Vehicle Driving Cycle.When engine operating condition changes, the inertia of turbosupercharger self makes its transient response characteristic relatively poor, need the regular hour from the foundation that changes to suction pressure of exhaust energy, not only affect the booster response characteristic of motor to mutational load, and caused emission performance and economic performance variation when accelerating because transient process is spun out.
In order to guarantee that motor has higher boost pressure and higher torque when the low speed, guarantee that simultaneously motor boost pressure when high speed is unlikely too high again, prevent the too high and turbosupercharger of engine heat load hypervelocity, should take corresponding technical measures to improve the torque characteristics of automobile-used turbosupercharged engine.
Regulate the method for nozzle blade aperture because of with the obvious advantage being widely applied of its engine performance improvement.Adopt variable nozzle turbocharger to compare with common pressurized machine, the low speed torque of motor, oil consumption, smoke intensity and transiting performance etc. have all obtained improvement to a certain degree.Variable nozzle turbocharger is when low engine speed, nozzle ring adjustable vane aperture is reduced, thereby improved the gas pressure of turbine inlet, namely improved the acting ability of turbine inlet gas, increased turbine drives moment, so the exhaust-gas turbocharger rotating speed is improved, boost pressure also improves; Otherwise when high engine speeds, nozzle ring adjustable vane aperture increases, and boost pressure then reduces relatively, and boost pressure is too high when preventing high speed.
The major defect of at present variable nozzle turbocharger existence is as follows:
1) traditional variable nozzle turbocharger nozzle ring adjustable vane drive unit all is installed on the intermediate part, transform fixed nozzle turbosupercharger modification as variable nozzle turbocharger if want, need intermediate and turbine part are carried out structural change simultaneously, complex manufacturing, commutative rate and the versatility of part are low, improve cost of production, be difficult for realizing industrialization production.
2) aperture of each nozzle ring adjustable vane of traditional variable nozzle turbocharger when design in full accord, be not inconsistent with the inlet air flow angle Changing Pattern of vehicular engine real work, increased energy loss.
3) in the part variable nozzle turbocharger, although the aperture of nozzle ring adjustable vane can be made along with the change of engine speed corresponding adjustment, but in use its performance is extremely unstable, reliability is relatively poor, may occur in the using process nozzle ring adjustable vane can not be fully by the situation of default regular movement, even stuck.Therefore, the application area of variable nozzle turbocharger is restricted, and is difficult to promote the use of on a large scale in vehicular engine.
