Embodiment
Embodiment oneA kind of three case turbocharging mechanisms
As shown in Figure 1, three case turbocharging mechanisms that present embodiment provides, comprise the parallel turbine group that is formed by be in parallel the first little turbosupercharger 4 and the second little turbosupercharger 5, also comprise the large turbosupercharger 6 that is in series with this parallel turbine group, between the gas inlet end of parallel turbine group and waste gas outlet side, be provided with exhaust gas by-pass valve 7, between the air inlet end of parallel turbine group and air outlet side, be provided with air bypass valve 8, between the gas inlet end of large turbosupercharger 6 and waste gas outlet side, be provided with bleed valve 9.
When exhaust gas by-pass valve 7 is closed, waste gas must flow through fully the first little turbosupercharger 4 and the second little turbosupercharger 5, thereby can drive parallel turbine group quick rotation, guarantee the low speed response performance, when air bypass valve 8 is opened, fresh air need not pass through the parallel turbine group, can not increase at a high speed by the time resistance, can guarantee high speed performance, when bleed valve 9 is opened, can bleed off part waste gas, avoid the rotating speed of large turbosupercharger 6 too fast.
Embodiment twoA kind of turbosupercharged engine
As shown in Figure 2, the turbosupercharged engine that present embodiment provides comprises the engine body 1 with suction tude 2 and steam outlet pipe 3, also comprises three case turbocharging mechanisms that embodiment one provides.Its air outlet side by the parallel turbine group that the first little turbosupercharger 4 and the second little turbosupercharger 5 form links to each other with the suction tude 2 of engine body 1, and the gas inlet end of parallel turbine group links to each other with the steam outlet pipe 3 of engine body 1.By the control to air bypass valve 8, exhaust gas by-pass valve 7 and bleed valve 9, can adapt to the whole speed range of motor.
Its concrete adjustment process is as follows:
When motor is in low speed, exhaust gas by-pass valve 7, air bypass valve 8 and bleed valve 9 Close Alls, the flow direction of fresh air as shown by the arrows in Figure 2 at this moment, the flow direction of waste gas is shown in the arrow among Fig. 3, and waste gas arrives its waste gas outlet side by the gas inlet end by the parallel turbine group, promotes the work of parallel turbine group in this process, guaranteed its low speed response performance, subsequently, waste gas is entered by the gas inlet end of large turbosupercharger 6, promotes large turbosupercharger 6 work.Fresh air is then behind process air-strainer 10, arrive the air inlet end of large turbosupercharger 6, be subject to being assigned to again after the supercharging of large turbosupercharger 6 the air inlet end of parallel turbine group, be subject to arriving behind the secondary booster of parallel turbine group the suction tude 2 of engine body 1.
When motor was in middle and slow speed of revolution, bleed valve 9 and air bypass valve 8 were closed, and exhaust gas by-pass valve 7 parts are opened, and as shown in Figure 4, identical when the flow direction of fresh air is with low speed at this moment, waste gas then can partly pass through exhaust gas by-pass valve 7.When waste gas process exhaust gas by-pass valve 7, it can increase the rotating speed of large turbosupercharger 6, thereby improves the FAI Fresh Air Intake amount, satisfies the air inlet requirement of motor middle and slow speed of revolution.
As shown in Figure 5, when motor is in middle high rotating speed, exhaust gas by-pass valve 7 and air bypass valve 8 standard-sized sheets, bleed valve 9 cuts out, at this moment, exhaust gas flow through exhaust gas by-pass valve 7 further increases, can improve the rotating speed of large turbosupercharger 6, mainly calm the anger by large turbosupercharger 6 this moment, can reduce the intake resistance that the parallel turbine group causes after air bypass valve 8 is opened when high speed, further improve air inflow, satisfy high-revolving air inlet requirement in the motor.
As shown in Figure 6, when motor was in high speed operation, exhaust gas by-pass valve 7, bleed valve 9 and air bypass valve 8 were all opened, and can prevent that the rotating speed of large turbosupercharger 6 is too fast after bleed valve 9 is opened, and made the motor stable operation.According to prior art, present embodiment also arranges intercooler between the suction tude 2 of the air outlet side of parallel turbine group and engine body 1, fresh air is lowered the temperature.
