Description

The calm the anger air-intake of combustion engine pressurized machine of progression of axial flow aerodynamic force combination in any

Technical field

The utility model belongs to the pressurized machine technical field, especially relates to the calm the anger air-intake of combustion engine pressurized machine of progression of a kind of axial flow aerodynamic force combination in any.

Background technique

Along with the development of technology, the requirement of people's combustion motor is also more and more harsher, not only will have powerful power, also must have high efficient and the discharging of clean enough.This just requires internal-combustion engine can both reach its most efficient working state under various operating modes, therefore just must satisfy internal-combustion engine demand for air inflow under each working state.This just requires each parts of internal-combustion engine to satisfy condition under different operating modes by " variable ".Such as Variable Valve Timing that we were familiar with, variable cross section turbocharging technology, variable intake manifold technology etc.

Existing internal-combustion engine generally adopts traditional natural aspiration mode, deficiency of air, fuel atomization and incomplete combustion, the tail gas severe contamination of discharge environment.How improving the efficient of internal-combustion engine and the discharging of minimizing tail gas is that pendulum is in the problem of auto industry field.

Summary of the invention

The utility model namely is for the problems referred to above, provide a kind of structure simple especially, the calm the anger pressurized machine of progression of the axial flow aerodynamic force combination in any of only having 8 Component to form, thereby its Component material is common to have preferably durability and reliability and has eliminated defective in the above-mentioned background technology, has solved the popularization and application problem of supercharger arrangement.

The calm the anger air-intake of combustion engine pressurized machine of progression of axial flow aerodynamic force combination in any, comprise diffusion barrel (1), connecting shaft impeller (2), bearing (3), M6 screw mandrel (4), floor clip (5), silica gel sealing ring (6), at diffusion barrel one end internal thread silk mouth is set, at the diffusion barrel the other end body external thread wire mouth and seal groove are set, on the connecting shaft impeller, impeller and axle are arranged to one, and each blade structure of axial flow turbine leaf is comprised of blade radial part and blade axial component.

When internal combustion engine operation, enter the air push first order blade radial part of suction port, when making blade rotary, again along sharf to the radial component that forms rotation forced air promotion second level blade, can make the rotating forced air thrust that superposeed again remove subordinate's turbine blade of promoting to intend combining, so analogize, make the device outlet end be input to air in the induction system of internal combustion engine, be not only greater than atmospheric pressure and be again the air-flow of High Rotation Speed. effectively improved the combustion performance of internal-combustion engine.When internal-combustion engine rotational speed strengthened or reduces, the variation of air pressure value can make the rotating speed of Multistage Axial Flow Turbines flabellum also will or reduce along with increase.

Electric turbine is the lifting power of dynamics greatly, exactly because but like this, the infringement of combustion motor is very large, a large amount of kinetic energy of its generation need to consume combustion engine powered, if the discharge capacity of internal-combustion engine own is low, can't consume the kinetic energy of its generation, this combustion motor is to have increased load, can produce potential impact.Secondly the cost long-life of electric turbocharger is short.

Exhaust gas turbine can be extraordinary lifting power, but the design accuracy of turbine height, complex manufacturing technology, bulky heaviness, price is high.The problem that exhaust gas turbine exists is that the power of driving turbine rotation is the high-temp waste gas (about 700 ℃) that internal-combustion engine is discharged, turbine and floating axle must use the high duty alloy material for this reason, the floating axle very easily axis of at high temperature working, this axis fault remains unsurmountable fault so far.

Because the internal-combustion engine natural inflow is subjected to the constraint of factors, general air inflow can only reach 65～90% of designing institute needs, and therefore internal-combustion engine also can only send 65～90% of former design power under the natural inflow state.Use the burning that has improved mixed gas behind this device, improve fuel economy and reduced the discharge amount of exhaust pollutant, therefore internal-combustion engine can send the peak output that former designing institute is demarcated.Simultaneously, it has the unexistent uniqueness of other turbosupercharger " high-speed screw air inlet function " to reach the special effect of " art is good for strength ".

Modern Internal-Combustion Engine is in order to improve natural inflow efficient, adopted many new technologies. such as " improving compression ratio; many valves; variable air inlet length suction tude; spiral hole suction tude, high flow capacity air filtering core, secondary air-in device " etc., but under present technical specifications, the utility model is unique device that can make internal-combustion engine increase output power in the constant situation of machinery, circuit, discharge capacity and operating mode.And to dispatch from the factory with in the old internal-combustion engine of inefficiency, the utility model may be to allow internal-combustion engine send one of best solution that former design demarcates peak output.

Compare with other turbosupercharger and the utlity model has that (only being made of 8 Component) simple in structure, easy to manufacture, cost lowly are convenient to popularize, long service life, advantage that cost performance is high.Be applicable to use various types of internal-combustion engines such as gasoline, diesel oil, ethanol petrol, rock gas.Every one-level can both be to prime conveying screw wind energy during work, and the plural serial stage combination just can be satisfied the demand of various internal-combustion engines, has solved the popularization and application problem of supercharger arrangement.
