Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
The engine charge assembly 100 for vehicle according to the embodiment of the present invention is described in detail referring to Fig. 1-Fig. 4.
As Figure 1-Figure 4, the engine charge assembly 100 for vehicle comprises gas compressor 120, compressor air inlet machine pipe 110, gas compressor steam outlet pipe 130, relief tube 140 and gas bleeder valve 150.
Wherein, gas compressor 120 is for the air inlet of compression engine 1000, to increase the density entering the gas of motor 1000, gas compressor 120 has inlet end 121 and outlet side 122, the inlet end 121 of gas compressor 120 is connected with compressor air inlet machine pipe 110, the outlet side 122 of gas compressor 120 is connected with gas compressor steam outlet pipe 130, relief tube 140 is connected between compressor air inlet machine pipe 110 and gas compressor steam outlet pipe 130, gas bleeder valve 150 is located on gas compressor steam outlet pipe 130, and with relief tube 140, gas bleeder valve 150 is connected that the gas in gas compressor steam outlet pipe 130 is expelled to compressor air inlet machine pipe 110 by relief tube 140.
Be understandable that, gas bleeder valve 150 optionally can control relief tube 140 and be communicated with compressor air inlet machine pipe 110 and gas compressor steam outlet pipe 130 or disconnect being communicated with of compressor air inlet machine pipe 110 and gas compressor steam outlet pipe 130.When force value in gas compressor steam outlet pipe 130 is excessive (closure 520 of such as motor 1000 is closed), gas bleeder valve 150 is opened, gas in gas compressor steam outlet pipe 130 can enter compressor air inlet machine pipe 110 by relief tube 140, to reduce the force value in gas compressor steam outlet pipe 130.
When high vehicle speeds, gas bleeder valve 150 is in closed condition, and gas from gas compressor suction tude 110 flows into gas compressor 120, and is compressed in gas compressor 120, then passes through the cylinder 510 of gas compressor steam outlet pipe 130 inflow engine 1000; When reducing throttle or braking, gas from gas compressor suction tude 110 flows into gas compressor 120, gas is compressed in gas compressor 120, pressurized gas flows into gas compressor steam outlet pipe 130, now the closure 520 of motor 1000 is in closed condition or opening is less, gas bleeder valve 150 is opened, and pressurized gas enters compressor air inlet machine pipe 110 by relief tube 140, prevents the force value in gas compressor steam outlet pipe 130 excessive.
According to the engine charge assembly 100 for vehicle of the embodiment of the present invention, by gas bleeder valve 150 is located on gas compressor steam outlet pipe 130, make the specification of gas bleeder valve 150 not by the restriction of gas compressor 120 structure, thus the larynx footpath of gas bleeder valve 150 can be increased, like this when opening gas bleeder valve 150 and losing heart, can greatly reduce disappointing noise.
As shown in Figure 1, gas compressor 120 can be the gas compressor 120 of turbosupercharger 200.
In preferred embodiments more of the present invention, shown in Fig. 1-Fig. 3, engine charge assembly 100 for vehicle can also comprise pressure-maintaining structure 160, and pressure-maintaining structure 160 can be located between the outlet of gas bleeder valve 150 and relief tube 140 with the preset pressure value making the force value of gas compressor steam outlet pipe 130 be more than or equal to gas compressor steam outlet pipe 130.
Be understandable that, the outlet of gas bleeder valve 150 can be connected by pressure-maintaining structure 160 with relief tube 140, after gas bleeder valve 150 is opened, gas in gas compressor steam outlet pipe 130 flows into compressor air inlet machine pipe 110 by relief tube 140 makes the force value in gas compressor steam outlet pipe 130 decline, when vehicle accelerates again, need the force value strengthening gas compressor steam outlet pipe 130, to increase the gas density entering cylinder 510.The force value in gas compressor steam outlet pipe 130 can be made to remain on preset pressure value or be greater than preset pressure value by arranging pressure-maintaining structure 160, being conducive to the acceleration again of vehicle, can providing air inflow to maximum flow, reduce the time for acceleration.
In a concrete example of the present invention, as shown in Figure 1-Figure 3, pressure-maintaining structure 160 can comprise housing 161 and pressure valve 162, to limit pressurize chamber I with the tube wall 131 of gas compressor steam outlet pipe 130 outside the tube wall 131 that housing 161 can be fixed on gas compressor steam outlet pipe 130.
After gas bleeder valve 150 is opened, the force value in pressurize chamber I becomes large, and pressure valve 162 is optionally communicated with according to the force value in pressurize chamber I or disconnects relief tube 140 and pressurize chamber I.
Be understandable that, pressure valve 162 has threshold value, when the force value in pressurize chamber I is greater than the threshold value of pressure valve 162, pressure valve 162 can be opened under the effect of pressure reduction, to make relief tube 140 be communicated with pressurize chamber I, the gas in pressurize chamber I and gas compressor steam outlet pipe 130 can leak into compressor air inlet machine pipe 110 to reduce the force value in pressurize chamber I and gas compressor steam outlet pipe 130 by relief tube 140; When the force value in pressurize chamber I is less than the threshold value of pressure valve 162, pressure valve 162 is closed, to disconnect being communicated with between relief tube 140 with pressurize chamber I, gas in pressurize chamber I and gas compressor steam outlet pipe 130 cannot be released by relief tube 140, remain on preset pressure value to make the force value in pressurize chamber I and gas compressor steam outlet pipe 130, in other words, the threshold value of pressure valve 162 can be more than or equal to preset pressure value.
Thus, by arranging pressure valve 162, make engine charge assembly 100 can remain on more than preset pressure value after gas bleeder valve 150 is opened, be conducive to the acceleration again of vehicle, there is provided air inflow with maximum flow, reduce the time for acceleration, and pressure leak process is pressure release step by step, namely gas compressor steam outlet pipe 130 is let out to pressurize chamber I, pressurize chamber I lets out to relief tube 140, can reduce noise when gas bleeder valve 150 is opened further.
Alternatively, as shown in Figure 1-Figure 3, pressure valve 162 can be located at the joint in relief tube 140 and pressurize chamber I.Thus, facilitate installation and the maintenance of pressure valve 162, and when pressure valve 162 is opened, the gas be beneficial in pressurize chamber I flows into relief tube 140, can reduce noise during cracking pressure valve 162.
Pressurize chamber I is limited jointly by the tube wall 131 of housing 161 with gas compressor steam outlet pipe 130, housing 161 can be configured to various structures, such as housing 161 can be configured to square, and housing 161 can be located at the side of gas compressor steam outlet pipe 130, or housing 161 can be configured to cylindrical, columniform housing 161 can limit annular pressurize chamber I with the tube wall 131 of gas compressor steam outlet pipe 130.
Pressurize chamber I can be optionally communicated with gas compressor steam outlet pipe 130 by gas bleeder valve 150 or be disconnected, in other words, open gas bleeder valve 150, pressurize chamber I can be communicated with gas compressor steam outlet pipe 130, close gas bleeder valve 150, pressurize chamber I and gas compressor steam outlet pipe 130 disconnect.
Preferably, the volume in pressurize chamber I is α with the ratio of the volume of gas compressor steam outlet pipe 130, and α can meet: 1≤α≤1.2.Be understandable that, open gas bleeder valve 150, pressurize chamber I can be communicated with gas compressor steam outlet pipe 130, namely pressurized gas in gas compressor steam outlet pipe 130 flows into pressurize chamber I by gas bleeder valve 150, the air pressure of gas compressor steam outlet pipe 130 can be reduced thus, the volume in pressurize chamber I and the ratio of the volume of gas compressor steam outlet pipe 130 are limited to the air pressure that above-mentioned scope contributes to reducing rapidly gas compressor steam outlet pipe 130, and the volume in pressurize chamber I is larger, when opening gas bleeder valve 150, the noise of gas flow is less.Alternatively, the volume in pressurize chamber I is equal with the volume of gas compressor steam outlet pipe 130.
Further, the valve seat 152 of gas bleeder valve 150 can be located on the tube wall 131 of gas compressor steam outlet pipe 130, and the spool 151 of gas bleeder valve 150 is removable to be located in pressurize chamber I to open or close valve seat 152.Be understandable that, valve seat 152 is parts of valve body, and be that valve body and being tightly connected of spool 151 are located, i.e. larynx footpath place, when spool 151 seals with valve seat 152, gas bleeder valve 150 cuts out, when spool 151 moves, produce gap between spool 151 and valve seat 152, now gas bleeder valve 150 is in open mode.
In other words, the valve seat 152 of gas bleeder valve 150 can be integrated with the tube wall 131 of gas compressor steam outlet pipe 130, the spool 151 of mobile gas bleeder valve 150, can open valve seat 152 to be communicated with pressurize chamber I and gas compressor steam outlet pipe 130.Said structure contributes to the area of the valve seat 152 expanding gas bleeder valve 150, and then can reduce the noise opening gas bleeder valve 150.
Particularly, gas bleeder valve 150 can be solenoid valve, spool 151 is closed valve seat 152 under the action of the spring, when gas bleeder valve 150 is energized, the spool 151 of gas bleeder valve 150 can overcome spring force and shrink to open gas bleeder valve 150, gas bleeder valve 150 can be communicated with pressurize chamber I and gas compressor steam outlet pipe 130, and the gas now in gas compressor steam outlet pipe 130 flows into pressurize chamber I to reduce the force value in gas compressor steam outlet pipe 130; During gas bleeder valve 150 power-off, the spool 151 of gas bleeder valve 150 closes gas bleeder valve 150 under the effect of spring force, and then disconnects gas compressor steam outlet pipe 130 and pressurize chamber I.
Preferably, gas bleeder valve 150 can be connected with the ECU of vehicle so that the ECU of vehicle controls gas bleeder valve 150 according to the working condition signal of vehicle and is energized.
Concrete, the working condition signal of vehicle comprises in engine rotational speed signal, plenum pressure signal, throttle position signal, vehicle speed signal, brake signal.Be understandable that, when motor 1000 reaches certain rotating speed, gas compressor 120 is just started working and is thought that motor 1000 provides pressurized gas, according to plenum pressure signal, the ECU of vehicle can judge that gas compressor 120 is in running order, particularly, plenum pressure signal represents the force value of the intake manifold of motor 1000, when gas compressor 120 is in running order, if reduction throttle, or the speed of a motor vehicle declines, or during to car brakeing, the air inflow that motor 1000 needs tails off, even the closure 520 of motor 1000 is closed, the ECU of vehicle can in conjunction with plenum pressure signal, throttle position signal, vehicle speed signal and brake signal control gas bleeder valve 150 and are energized, be communicated with pressurize chamber I to make gas compressor steam outlet pipe 130, thus the force value reduced in gas compressor steam outlet pipe 130, prevent gas compressor 120 and closure 520 under high pressure damaging.
Further, when plenum pressure signal is reduced to the force value of setting, the ECU of vehicle can control gas bleeder valve 150 power-off according to plenum pressure signal, and the force value of setting is less than preset pressure value.When the force value of the intake manifold of plenum pressure signal display motor 1000 is reduced to force value (the approximating atmospheric pressure) of setting, now gas compressor 120 quits work, the ECU of vehicle can control gas bleeder valve 150 power-off according to this plenum pressure signal, to disconnect gas compressor steam outlet pipe 130 and pressurize chamber I, now motor 1000 is equivalent to naturally aspirated engine.
The ECU of vehicle can also control gas bleeder valve 150 power-off according to plenum pressure signal, engine rotational speed signal, throttle position signal and vehicle speed signal.Particularly, after gas bleeder valve 150 is energized, the force value of the intake manifold of motor 1000 declines, but this force value does not also drop to the force value (approximating atmospheric pressure) of setting, namely when plenum pressure signal is higher than the force value set, if now open the throttle, the air inlet quantitative change that motor 1000 needs is many, the ECU of vehicle can control gas bleeder valve 150 power-off in conjunction with plenum pressure signal, engine rotational speed signal, throttle position signal and vehicle speed signal, to disconnect gas compressor steam outlet pipe 130 and pressurize chamber I, thus promote the force value of gas compressor steam outlet pipe 130.
Thus, the unlatching as required of gas bleeder valve 150 can be realized simply, to reduce the force value in gas compressor steam outlet pipe 130 in time.
According to the engine charge assembly 100 for vehicle of the embodiment of the present invention, the inlet end 121 of gas compressor 120 is connected with compressor air inlet machine pipe 110, the outlet side 122 of gas compressor 120 is connected with gas compressor steam outlet pipe 130, the tube wall 131 of gas compressor steam outlet pipe 130 and be fixed on gas compressor steam outlet pipe 130 tube wall 131 outside housing 161 jointly limit pressurize chamber I, and the volume of the volume in pressurize chamber I and gas compressor steam outlet pipe 130 is roughly equal, gas bleeder valve 150 can be provided with between pressurize chamber I and gas compressor steam outlet pipe 130, and the valve seat 152 of gas bleeder valve 150 can be located on the tube wall 131 of gas compressor steam outlet pipe 130, gas bleeder valve 150 can be connected with the ECU of vehicle, and the ECU of vehicle can be energized or power-off according to the working condition signal control gas bleeder valve 150 of vehicle, relief tube 140 is connected between compressor air inlet machine pipe 110 and gas compressor steam outlet pipe 130, and relief tube 140 is provided with pressure valve 162 with the joint in pressurize chamber I, pressure valve 162 has threshold value, during the threshold value of the force value in pressurize chamber I higher than pressure valve 162, pressure valve 162 is opened, during the threshold value of the force value in pressurize chamber I lower than pressure valve 162, pressure valve 162 is closed.
As shown in Figure 4, the working principle of the engine charge assembly 100 for vehicle according to the embodiment of the present invention is described below:
When high vehicle speeds, gas bleeder valve 150 is in closed condition, and gas from gas compressor suction tude 110 enters gas compressor 120, and is compressed in gas compressor 120, then flows into cylinder 510 by gas compressor steam outlet pipe 130.
To car brakeing, or reduction throttle, or when reducing the speed of a motor vehicle, the ECU of vehicle controls gas bleeder valve 150 according to the working condition signal of vehicle and is energized, gas bleeder valve 150 is opened, and the gas now in gas compressor steam outlet pipe 130 flows into pressurize chamber I to reduce the force value in gas compressor steam outlet pipe 130.
If the force value in pressurize chamber I is higher than the threshold value of pressure valve 162, then pressure valve 162 is opened under the effect of pressure difference, relief tube 140 is communicated with pressurize chamber I, and the gas in pressurize chamber I and gas compressor steam outlet pipe 130 can leak into compressor air inlet machine pipe 110 to reduce the force value in gas compressor steam outlet pipe 130 further by relief tube 140.
