Background technology
Turbocharger is broadly divided into constant cross-section booster and the major class of variable cross-section pressure booster two.
It is changeless, and the capacity of engine that the volute waste gas of the turbine of constant cross-section booster, which flows through passage,
What it is with rotating speed is not both change, therefore constant cross-section turbocharger can only be in operating point for design efficient operation, this kind of whirlpool
Wheel booster can not take into account high low-speed performance simultaneously, otherwise low-speed performance is poor, or by high speed stage, abandoning a part
Exhaust energy, to improve low-speed performance.
Variable section turbocharger can effectively take into account high low-speed performance, but complicated, to parts machining precision with
Craft precision requires all very high；Its structure has many kinds, and the structure of main flow is variable-nozzle ring type, and it is arranged on whirlpool by one group
The movable guide vane of leading edge is taken turns, to change direction and the area of section of the gas for flowing to turbine, so that variable geometry turbocharger
The booster moment is operated in high efficient area, has taken into account low speed and large torque, the requirement of high-speed high-power.
