Description
Technical field
The invention belongs to engine turbine supercharging technology field, it is related to a kind of turbocharger in axially variable section.
Background technology
Turbocharger be it is a kind of increase the device of air inflow by compressed air, it be using engine discharge it is useless
Gas inertia impulsive force promotes the turbine in turbine room, and turbine drives coaxial compressor impeller again, compressor impeller force feed is by sky
The air that air cleaner pipeline is sent, is allowed to supercharging and enters cylinder.When the engine rotational speed is increased, the waste gas velocity of discharge and turbine
Rotating speed also synchronously increases, and compressor impeller just compresses more air and enters cylinder, and pressure and the density increase of air can fire
More fuel are burnt, the rotating speed of fuel quantity and engine are correspondingly increased, and then increase the power output of engine.Due to car
The different road conditions of adaptation and load are needed with engine, its working condition is often continually changing, and this is accomplished by matching with it
Turbocharger the features such as there is wide operating flow range, small turbo lag and big high efficiency region.
Common turbocharger is matched according to the rated power of engine, when engine is transported in low operating mode
During row state, because rotating speed is low, the pressure at expulsion of engine is low, causes turbocharger generation compressed air density also low, hair
The inlet air charge number of motivation can be reduced quickly, cause deficiency of air so that the fuel in cylinder can not be abundant
Burning, not only fuel consumption is high, and occurs that over-emitting black exhaust, excessive discharge temperature, noxious gas emission be exceeded, low speed torque
The defect such as small.In order that engine can meet the requirement of full combustion of fuel under different working conditions, existing whirlpool is solved
The problems such as pressurized effect is not obvious when taking turns the turbo lag of booster generally existing, engine power output nonlinear, the slow-speed of revolution,
The exhaust gas intake port section timely adjustment of turbocharger must be enable, the turbocharger of variable cross section is then just generated.
At present, the turbocharger of variable cross section in actual applications, can still come with some shortcomings in terms of Performance Match.
The aperture of variable-vane in variable-area turbocharger nozzle ring is adjusted external control system, engine discharge
Waste gas obtains certain speed of prewhirling by jet blade, then flows into turbo blade, to obtain higher efficiency.But, its
Regulative mode is essentially stage regulation, i.e., only two or limited work aperture gear, it is difficult in whole service operating mode all
High efficiency is kept, and variable nozzle ring reliability is poor, requires high to the accuracy of manufacture, and due to the nozzle ring leaf of common material
Piece can not adapt to the high-temperature exhaust air of engine, thus also there is the deficiencies such as complicated and manufacturing cost is high.
