Embodiment one:
As shown in Figure 3, Figure 4, waste expansion mechanism comprises first, second turbo machine 22,23 being separately positioned on turbine shaft 21 two ends, the suction port of the first turbo machine 22 is connected with master cylinder gas exhaust manifold 17 by the first pipeline 24, the relief opening of the first turbo machine 22 is communicated with the suction port of the second turbo machine 23 by second pipe 25, and the relief opening of the second turbo machine 23 is communicated with air.
Further, the neutral position of turbine shaft 21 is coaxially provided with gear 26, and gear 26 is connected with the gear of master cylinder bent axle 13 by retarder 27.
Preferably, as shown in Figure 5, master cylinder 1 is set up in parallel two, and two master cylinder gas exhaust manifolds 17 are connected with the first pipeline 24 respectively.The advantage arranging two master cylinders is that twin-tub can to the continuous air feed of turbine mechanism, and turbine efficiency is relatively high, and exhaust pressure wave can not produce interference to the scavenging later stage simultaneously, can not produce waste gas refluence phenomenon.More preferred, two master cylinders 1 are symmetrical arranged, and the master cylinder valve 16 on two master cylinders 1 is near arranging.The side of oil nozzle and spray oxygen mouth master cylinder valve, when selecting two master cylinder arrangement, two master cylinders are symmetrical arranged, namely two master cylinder valves are pressed close to arrange mutually, distance between such two master cylinder valves is little, make two master cylinder gas exhaust manifolds to be communicated with setting, two master cylinder gas exhaust manifolds can share first pipeline and be connected with the suction port of the first turbo machine, the more compact structure of motor.
