Referring to accompanying drawing 1 and accompanying drawing 5, it is existing six cylinder bypass type turbosupercharger.This turbocharger arrangement is comparatively simple, the waste gas inlet of turbosupercharger is made of runner A 2 and runner B 3, turbosupercharger is opened venting valve 12 by bypass valve 5 and is drained a certain amount of waste gas from exhausting waste gas hole 4 under the high engine speeds state, prevents pressurized machine hypervelocity.
Referring to accompanying drawing 2-accompanying drawing 6, it is schematic representation of the present utility model.Its structure is: it comprises gas compressor part and turbine part, described gas compressor partly comprises compressor housings 13, compressor impeller, air inlet 29 and air outlet slit pipe 14, described turbine portion branch comprises turbine shroud 1, turbine and the double flow channel waste gas inlet that is formed by runner A 2 and runner B 3, the coaxial installation of compressor impeller and turbine, key improvements make and also comprise the regulating device that is fixed in the circulation area that is used for adjusting turbine exhaust suction port runner on the turbine shroud 1.
Described regulating device comprises the waste gas guide plate 7 of being located at runner A 2 or runner B 3 places, first rocking arm 8 that is connected with the rotating shaft 9 of waste gas guide plate 7 and the exhaust gas flow controller 6 hinged with first rocking arm 8, described exhaust gas flow controller 6 is communicated with compressed air outlet pipe 14, the top of described first rocking arm 8 is provided with for the rocking arm position limit pin 28 of setting turbine box maximum flow sectional area, and described rocking arm position limit pin 28 is located on the turbine shroud 1.Described exhaust gas flow controller 6 is positioned on the turbine shroud 1 by mounting bracket 16.Rocking arm position limit pin 28 is to change in the scope of a setting for the runner that limits the turbosupercharger waste gas inlet, can set as required when pressure acquires a certain degree, and the aperture of waste gas guide plate 7 no longer increases.
The structure of the above exhaust gas flow controller 6 has dual mode: a kind of is directly to adopt bypass valve I (perhaps being final controlling element), and the push rod 15 of described bypass valve I and first rocking arm 8 are hinged.
Another kind of mode is that the bypass valve I is once improved, set up for the control handle 25 of controlling its initial pressure on the top of bypass valve I, the upper shell 26 that described control handle 25 passes the bypass valve I is pressed on the flexible sheet 24 of bypass valve I, and the push rod 15 of described bypass valve I and first rocking arm 8 are hinged.Referring to accompanying drawing 6, the structure of exhaust gas flow controller 6 is: described exhaust gas flow controller 6 comprises the cavity that is formed by upper shell 26 and lower shell body 20, pierce into the control handle 25 of cavity and the push rod that upwards pierces into cavity from lower shell body from upper shell, be provided with flexible sheet 24 between described control handle 25 and the push rod 15, be provided with the pad 23 that is sheathed on the push rod 15 in the cavity from top to bottom successively, diaphragm seat 22, spring 21, lower spring cup 19, felt 18 and positioning plate 17, described upper shell 26 sides are provided with valve 27, and this valve 27 is communicated with by pipe with compressed air outlet pipe position.
Referring to accompanying drawing 3, turbosupercharger is under waste gas situation less under the motor slow-speed of revolution, and exhaust gas flow controller 6 drives first rocking arm 8, and then drives rotating shaft 9 and drive waste gas guide plate 7 state as shown in Figure 3 of working.Have only runner A2 to carry out work under this state, thereby the turbine rotor rotating speed of turbosupercharger can improve, can bring more high pressure ratio fresh air to motor, thereby oil inflame is more abundant under the low engine speed operating mode, the fuel economy of motor, power character all can rise, and discharging also can be better.Exhaust gas flow controller 6 has a pretightening force, be to hold first rocking arm 8 with push rod 15 under the turbocharger low speed state, and after supercharger speed raises, stream pressure in the gas compressor raises, when equal pressure is increased to limit value, the exhaust gas flow controller has overcome previous pretightening force by push rod, drives waste gas guide plate 7 and begins the exhaust gas flow that enters turbosupercharger is adjusted.
