Description
Technical field
The utility model is a kind of dynamic power machine, and this device can utilize the SHOCK ENERGY of gaseous fuel in the knocking combustion generation of firing chamber, is used for the turbine of auxiliary drive exhaust-gas turbocharger, belongs to the Thermal Energy and Power Engineering field.
Background technique
Turbosupercharger is a kind of technology of utilizing the exhaust gas driven air compressor of internal-combustion engine generation, and turbo charging installation is exactly a kind of air compressor in fact, increases the air inflow of motor by pressurized air.Turbosupercharging all is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, and turbine drives coaxial impeller again, and the impeller force feed is made it supercharging and entered cylinder by fresh air, realizes the supercharging purpose.The use of turbosupercharger helps improving engine power performance, at present in the extensive use Vehicular internal combustion engine.
When turbosupercharger is used on motor, it be not at any time all startup play a role.In the vehicle start stage, engine speed is low, operating temperature is low, the exhausted air quantity that motor is discharged is less, this moment, temperature cylinder was relatively low, the contained very most heat of waste gas dissipates through transmission of heat, and low-energy waste gas does not have enough to promote the effectively inertia impulsive force of running of turbine after entering the booster turbine chamber naturally, and this moment, turbine was difficult to start.Therefore, do not work substantially, do not realize the purpose of supercharging this moment in vehicle start stage turbosupercharger.
In order to solve exhaust-gas turbocharger in the problem that is difficult to start in vehicle starting stage, the purpose of this utility model is that a kind of motive power machine device of exploitation is used for the startup of assisted turbocharger in the vehicle starting stage.
The model utility content
The utility model device is to develop a kind of novel auxiliary power unit for solving exhaust-gas turbocharger in the problem that is difficult to start in vehicle starting stage, this apparatus structure is comparatively simple, burning can effectively utilize the energy of fuel combustion rapidly, has greater efficiency.It is characterized in that: the SHOCK ENERGY that will utilize the gaseous fuel knocking combustion to produce drives the turbine of turbosupercharger.
The turbosupercharger auxiliary power unit sketch of the utility model design is seen accompanying drawing 1, comprises air inlet pipe 7, gas fuel inlet pipe 8, air intake control valve 6, flame tube 9, igniter 5 and flame tube control valve 10; Flame tube 9 is long tubes that one one end seals an end opening, is provided with igniter 5 at closed end, and opening end is communicated with the turbine inner chamber, and opening end is equipped with flame tube control valve 10; Below flame tube 9 closed ends, be provided with air inlet pipe 7 and gaseous fuel inlet duct 8; Be provided with air intake control valve 6 between air inlet pipe 7 and the flame tube 9.
The utility model is by gaseous fuel (can be rock gas or hydrogen) and air mixing and light, the detonation in shock tube of the gas of burning produces shock wave, and gas is through shock wave compression excitation, its pressure, density, temperature all can suddenly raise, high temperature and high pressure gas can drive the turbine high-efficient operation forcefully, assisted turbocharger can normally play a role in low temperature slow-speed of revolution operating mode, improves engine power performance.
The utility model and not this device relatively can effectively utilize the energy of fuel combustion, engine power performance can improve 15-20%, has greater efficiency.

Embodiment
Describe the utility model in detail below in conjunction with Fig. 1～3.
Present embodiment mainly is made up of gas handling system (air inlet pipe 7, gas fuel inlet pipe 8 and air intake control valve 6), combustion system (flame tube 9, igniter 5 and flame tube control valve 10).
Embodiment of the present utility model is:
During original state, two control valves, promptly air intake control valve 6 and flame tube control valve 10 are all closed, turbine 1 transfixion.When engine start, turbine speed sensor 12 begins to survey secondary speed, and when the signal that returns ECU when turbine speed sensor started rotating speed less than turbine, ECU sent instruction, and the turbine auxiliary power unit starts, and starts working.
Air inlet: the turbine auxiliary power unit starts initial, from the gaseous fuel of gas fuel inlet pipe 8 with even from the air mixing of air inlet pipe.Then, open air intake control valve 6, fuel-air mixture 3 enters flame tube 9.After fuel-air mixture was full of flame tube 9, air intake control valve 6 was closed, and intake process finishes.
Burning: open igniter 5 when air intake control valve 6 is closed, igniter 5 is lighted formation flame with the fuel and the Air mixing gas that mix.Flame forms knocking combustion after the propagation of flame tube 9 through a segment distance, and produces shock wave.Shock wave makes and produces high pressure in the catchment of flame tube, and promptly gas velocity, the temperature in the outlet port of flame tube 9 raises.Simultaneously, the flame tube control valve 10 that is positioned at the flame tube end is opened, and is communicated with turbine inner chamber 11 and flame tube 9.High temperature and high speed gas flows out also from flame tube 9 and enters rapidly the turbine inner chamber 11, under the driving of the energy of gas of combustion, waste gas acts on and produces a moment (driving moment) on the turbine blade 2, and this driving moment is ordered about turbine blade and rotated, and turbosupercharger is started working like this.
Stop: when turbine speed sensor 12 measures secondary speed when reaching the startup rotating speed of its design, ECU sends instruction and cuts off gaseous fuel and supply with, and closes flame tube control valve 10 simultaneously, and burning stops, and auxiliary power unit quits work.This moment, the rotating speed of motor improved, and the exhaust gas temperature that motor is discharged raises, engine exhaust energy drives turbine fast rotational.After this, turbine proper functioning.
