Description

Aerodynamic turbosupercharging devic 3

The present invention relates to a kind of aerodynamic turbosupercharging devic 3, the device that its blower outlet end is connected with the air inlet nose end of diesel engine or is connected with petrolic vaporizer mouth end, various motors are loaded onto it can both be increased output power, reduces oil consumption and improve blowdown.

The engine booster apparatus has several, and the device of finalizing the design both at home and abroad mainly is the product of the H series of exhaust-gas turbocharger device at present, and the motor that operates at the plateau section is because atmospheric pressure is low, and engine output all is lower than the power of declared working condition.As: the motor that operates at China Tibet plateau area only can be exported about 70% of declared working condition power, and various motors are loaded onto it, can both solve the problem of the low output power deficiency of plateau section atmospheric pressure.But the problem that the exhaust-gas turbocharger device exists is the power that drives the turbine rotation is that waste gas for this reason for the motor high temperature (about 700 ℃) of discharging, turbine and floating axle must adopt high-quality heat resisting alloy steel, in order to improve the turbine rotation efficiency, the design accuracy height of turbine, complex process, floating axle is in high temperature (about 700 ℃) and (120000r/min) running event down at a high speed, the easy gum deposit matter of the oil channel hole of floating axle is stopped up oil duct, causes the floating axle in the device not float and axis.For this reason, the durable and poor reliability of device, this problem that floating axle is stuck also is a problem that is difficult to resolve of domestic and international exhaust-gas turbocharger device factory so far.For this reason, on the operating instruction of device, emphasize that all device proper must install filter., the fault of axis also remains unsurmountable fault so far, the big and Heavy Weight of device proper volume.

Solve the problem that the exhaust-gas turbocharger device exists: the delivery temperature of general reduction motor still, the row temperature of motor under declared working condition be low more also to be not less than hundreds of degree centigrade.So, the potentiality that reduce row's temperature are also little, especially the factory of the famous brand exhaust-gas turbocharger device produced of China, all be to buy the factory that Britain Hall plug secret service journey Co., Ltd (Holset EngineeingCompany Limited) technology transfer license is made H series exhaust-gas turbocharger device, do not allow to change drawing.The patent that Korea S declares: whirlwind supercharger arrangement, feature are to be provided with the fixing spiral leaf of several leaves in the fixing cylindrical sleeve, and it is contained in the air-strainer of various motors.

The purpose of this invention is to provide a kind of aerodynamic turbosupercharging devic 3, the power that has fundamentally solved driving turbine rotation in the device is the air in the atmosphere, the air that is pressed into outlet end in the device is a swirling eddy, removed the effect of high temperature (700 ℃) waste gas of motor discharge, thereby effectively solved the durable and reliability of device proper, part material is common, and the device that makes simple in structure has obtained popularization and application.

The object of the present invention is achieved like this: the turbine chamber in the device is a communication chamber with the unit room of calming the anger, the suction port end sucks in the device when motor one running, and to be that air in the atmosphere enters gas compressor along the axial blade of turbine indoor, produce swirling eddy, be pressed into the outlet end of device, because the device that the outlet end of device is connected with the air inlet nose end of diesel engine or is connected with petrolic vaporizer mouth end.So, being pressed into the air of outlet end in the device, the suction pressure (P1) that has not only improved motor has entered in the gas handling system of motor for swirling eddy again simultaneously.

The starting point of the present invention is that aerodynamic turbosupercharging devic 3 is on structural design, the power that emphasis has solved the turbine rotation is that the effect of the high-temp waste gas of discharging of air and the motor in the inletting device has nothing to do, so because the rotation of centripetal turbine in the device, air enters that gas compressor is indoor to have produced the outlet end that swirling eddy is pressed into device.

The concrete theoretical foundation of device of the present invention: the motor of supercharger arrangement is housed, effective compression ratio (ε _e) and (P1/T1) increased scavenging efficiency (η _a) improved, thereby reduced the coefficient of residual gas (γ of motor _R).So, the charging efficiency (η of motor _v) improved.

η_{v_} = \frac{ϵ_{e}}{ϵ - 1} \times \frac{P 1}{T 1} \times \frac{Ts}{Ps} \times (1 - (1 - η_{s})) \times \frac{\Pr}{Tr} \times \frac{T 1}{P 1} \times \frac{1}{ϵ_{e}} - - - - (1)

Because η _vSo improved, the mean effective pressure of motor (Pe) value has also just improved.

Pe = 1.46 \frac{η_{v} \times Hu \times η_{e} \times Ps}{λ \times Lo \times Ts} (KPa) - - - - (2)

So because the Pe value has improved, the useful horsepower of motor (Ne) value has also improved.

Ne = \frac{Pe \times Vh \times n \times i}{450} (kw) - - - - (3)

Because (3) thus the raising of formula Ne value, the specific fuel consumption of motor (ge) value has also just improved.

ge = \frac{1000 G}{Ne} (g / kw \cdot h) - - - - (4)

Shown by above-mentioned mathematical expression demonstration: aerodynamic turbosupercharging devic 3, being contained on the various motors to increase output power, reduces oil consumption and improves blowdown.

Apparatus structure of the present invention is simple especially, and part material is common to have durable preferably and reliability, the popularization and application that has solved supercharger arrangement.

Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the complete section plan view of the aerodynamic turbosupercharging devic 3 of proposition according to the present invention.
