Abstract
The utility model relates to a lemniscate helical air-intake pressurizer, which comprises an air compressor air-intake port, an air compressor wind guide wheel, an air compressor wind guide wheel front section, an air-intake channel, an intermediate body and a turbine shell, wherein the air compressor air-intake port adopts a lemniscate air-intake path, and the air compressor wind guide wheel front section is provided with at least one helical air entraining groove. According to the lemniscate helical air-intake pressurizer, the air-intake channel of the pressurizer is creatively designed under the conditions of not changing the integral structure of the pressurizer and not increasing any parts and components, the flow resistance and the flow energy loss of air intake are reduced, so that prewhirl is generated during air intake, the air flow is increased and the efficiency of the pressurizer is improved.
Description
[technical field]
The utility model relates to a kind of engine pack, particularly a kind of lemniscate spirally inlet air pressurized machine.
[background technique]
Turbosupercharger is a kind of device that can improve engine power, reduce engine emission, is widely used on the various motors.Along with the implementation of Europe IV, Europe V discharging, require the more air demand of air supply system ability of motor, because the cylinder volume is certain, increase air demand, have only the further compression of air inlet with the raising air inflow.Therefore, require pressurized machine that higher efficient is arranged, to satisfy the requirement of motor.At present common pressurized machine is because efficient is not high, and air demand is limited, can not satisfy the requirement of Europe IV, Europe V motor, has limited the development of pressurized machine.
[summary of the invention]
In view of the problem that present known technology exists, the technical problem that the utility model will solve just provides a kind of high efficiency, can satisfy the requirement of IV Europe, Europe V discharging motor, can satisfy the pressurized machine of the lemniscate spirally inlet air of pressurized machine development simultaneously.
For solving the problems of the technologies described above; The utility model takes following technological scheme to realize: a kind of lemniscate spirally inlet air pressurized machine; Comprise compressor air inlet machine mouth, gas compressor inducer, gas compressor inducer leading portion, intake duct, intermediate, turbine case, it is characterized in that: said compressor air inlet machine mouth adopts lemniscate air inlet path.Tradition compressor casing of pressurizer suction port is to adopt right angle or obtuse angle linear structure, and this structure is hindered air flow to here the time, produces eddy current, increases air flow resistance, thereby has reduced the air inflow of pressurized machine, has reduced the efficient of pressurized machine.The utility model product is through utilizing the calculating of aerodynamic principle and fluid mechanics principle, and air gets into the resistance minimum of the air inlet section of compressor casing of pressurizer along the lemniscate path flow, and the energy of flow loss is also minimum.Therefore, this invention is designed to the path of lemniscate form with the compressor casing suction port, has reduced the loss of inlet stream dynamic resistance and energy of flow; Increased air inflow, improved efficiency of turbocharger, thereby improved pressure ratio; Increase engine power; Reduce engine emission, satisfy stricter emission request, like the requirement of IV Europe, Europe V Abgasgesetz.
The utility model product gas compressor inducer leading portion is designed to spiral bleed groove structure, and this structure guiding air gets into gas compressor along the compressor impeller sense of rotation, has produced and has prewhirled, and has increased air mass flow, thereby has increased engine power, has improved engine emission.
The beneficial effect of the utility model is: do not changing supercharger integrated structure, do not increasing under the situation of any component the intake duct of innovative design pressurized machine; Realized having reduced the loss of inlet stream dynamic resistance and energy of flow, generation is prewhirled, and has increased air mass flow; Improve efficiency of turbocharger; Improve engine efficiency, satisfied the requirement of Europe IV, Europe V motor, helped the pressurized machine better development.
Below in conjunction with accompanying drawing the utility model is further specified:
[description of drawings]
Fig. 1 is plain edition pressurized machine assembly figure;
Fig. 2 is the utility model pressurized machine assembly figure;
Among the figure: 1. compressor air inlet machine mouth, 2. gas compressor inducer leading portion, 3. gas compressor inducer, 4. intake duct, 5. spiral bleed groove, 6. intermediate, 7. turbine case.
[embodiment]
Like Fig. 1, the described a kind of lemniscate spirally inlet air pressurized machine of Fig. 2; Comprise compressor air inlet machine mouth 1, gas compressor inducer leading portion 2, gas compressor inducer 3, intake duct 4, intermediate 6, turbine case 7; Compressor air inlet machine mouth 1 adopts lemniscate air inlet path, and what adopt like the compressor air inlet machine mouth 1 of traditional pressurized machine of Fig. 1 is right angle or obtuse angle linear structure, and this air intake structure is hindered air flow to here the time; Produce eddy current; Increase air flow resistance, thereby reduced the air inflow of pressurized machine, reduced the efficient of pressurized machine.And the utility model is through utilizing the calculating of aerodynamic principle and fluid mechanics principle, and along the lemniscate path flow, the resistance that receives was minimum when air got into supercharger air compressor suction port 1; The energy of flow loss is also minimum, therefore can improve the efficient of pressurized machine, in the present embodiment; Gas compressor inducer 3 leading portions also are provided with 4 road spiral bleed grooves 5; This structure guiding air gets into gas compressor along gas compressor inducer 3 sense of rotation, has produced and has prewhirled, and has increased air mass flow; Thereby the increase engine power has been improved engine emission.
