| 摘要 |
<p>This invention relates to an apparatus for driving a turbo supercharger in which a negative pressure is generated by accelerating the gas flow in an internal combustion engine (10). A turbine (40) is driven by this negative pressure. A supercharging turbine (50) is operated with this turbine (40), and as the suction air is pressurized beforehand, the energy of the exhaust gas flow acts on the turbine (40) by connecting the upstream side of the turbine (40) to an exhaust system pipe (20). A low-pressure suction air flow acts on the downstream side of the turbine (40). In this way, the exhaust gas flow discharged to the turbine outlet (44) is absorbed, and the turbine (40) is driven by the energy of the exhaust gas which flows through the exhaust system pipe (20) by suction force as well as by a powerful negative pressure, which is generated separately. A negative-pressure generator (30) is provided at the lowermost downstream side of the exhaust system pipe (20) to generate the suction force. <IMAGE></p> |
