Description
Technical field
The present invention relates to a kind of exhaust-gas turbocharger system with three grades of adjustable nozzles, belong to field of mechanical technique.
Background technique
Current exhaust-gas turbocharger technology has been widely used on internal-combustion engine, can improve output power of internal combustion engine, reduces the discharge of specific power oil consumption and minimizing harmful gas and deleterious particle thing.But to vehicular engine because of its variable working condition continually, the pressurized machine some work period can be made to be in the work of non-efficient district, thus to reduce pressurized effect, not reach energy-saving and emission-reduction index.
In order to the reality making pressurized machine adapt to vehicular engine variable working condition, the measure now adopted the on-bladed runner turbine case 4 in original structure is changed into form three grades of nozzles by adjustable 1,2,3 mechanisms of blade, jet area is changed with the needs of motor variable working condition, to expand pressurized machine efficient district operating range, reach energy-conservation, increase output power, the object of emissions reduction.
Adopt adjustable nozzle structure to be improve the effective ways of turbine pneumatic performance, one of energy-conservation, main environmental protection solution that each pressurized machine specialized factory of the Ye Shi world generally acknowledges, and progressively promotion and implementation, have several different technological scheme at present:
First be exactly the variable-nozzle method adopting rotor blade angle by Honeywell Int Inc of U.S. patent applied for number 200710152744.5 " vane group of variable nozzle turbocharger and the assembling methods of blade assembly ".Its advantage is that the cross-section area of nozzle reduces with blade rotating angle and reduces, and nozzle area slip can reach more than 70%, and pressurized machine thermal efficiency when low high operating mode work is declined.
Also have by the variable cross section structure of the French Honeywell Garrett Co., Ltd number of applying for a patent 00819834.9 " the form-varied turbosupercharger with sliding piston " simple, nozzle half is by stator blade, and second half forms by without leaf air flue.Adjustable area only has this half of air flue.But its aeroperformance is bad.When opening without leaf passage, air-flow will flow through from blade path with without leaf passage simultaneously, because the flow angle of two passages is not identical, will cause the air turbulence after nozzle, increase air current flow loss, reduce turbine heat efficiency.
The turbosupercharger of the double-vane nozzle systems applied for by Chinese Wuxi Kaidi Booster deler Co., Ltd., the patent No. 201110233106.2; International application no PCT/CN2012/001087; The U. S. application number of accepting 9376.
The turbosupercharger of the double-vane nozzle systems that Wuxi Kaidi Booster deler Co., Ltd. of China proposes, along the new blade placed in nozzle flow channel, can reduce cross section of fluid channel and amass, again former nozzle is separated into two air flues, to reduce gas flow sideways loss.Air-flow still moves by intrinsic best air-flow angular flux simultaneously, improves the expansion in efficient turbine district.
But the above technological scheme, cannot meet and regulate runner scope, regulate runner scope extremely important to working state when improving motor ultra high speed, low speed.
