Background technique
Because power character, fuel economy and minimizing exhaust pollution that exhaust gas turbine can improve motor significantly, so it has obtained using widely on various motors.
Exhaust-gas turbocharger has experienced low speed (high workload rotation speed n
Max≤ 40000r/min) to common high speed (n
Max〉=100000r/min), regulate the development in four generations of stepless continuous can regulate to single-stage.Wherein: the low speed exhaust-gas turbocharger of the first generation has only obtained application in marine engine and part generator set; The invention of wholly floating bearing in 1958 after making the rotating speed of exhaust-gas turbocharger reach and surpassing 100000r/min, has just been drawn back the prelude that exhaust-gas turbocharger is used on Vehicular internal combustion engine.Because common high-speed exhaust gas turbosupercharger (hereinafter to be referred as the common exhaust turbosupercharger) exists: pressurized effect deficiency when the little load operation of low engine speed, pressurized effect is crossed strong shortcoming during the motor large load operation; So the band bypass valve formula exhaust-gas turbocharger (being commonly called as band bypass valve formula exhaust-gas turbocharger) that it is regulated by single-stage gradually replaces.In order to adapt to the requirement of automobile emission regulation day with strictness, each state is all greatly developing the adjustable automatically controlled variable voluted type exhaust-gas turbocharger of stepless continuous (being called for short automatically controlled variable voluted type exhaust-gas turbocharger) at present.
The common feature of band bypass valve formula exhaust-gas turbocharger and automatically controlled variable whirlpool formula exhaust gas turbine is: the supercharging needs of looking after the little load of low engine speed on structural design as much as possible, to avoid the surge of motor, and along with the increase of engine load or rotating speed, in case pressurized effect occurs when excessive, for band bypass valve formula exhaust-gas turbocharger, then open bypass valve, the exhausted air quantity that enters into exhaust-gas turbocharger is reduced, to reduce the pressurized effect of pressurized machine; For automatically controlled variable voluted type exhaust-gas turbocharger, then increase the flow area of volute, reduce utilization, to reduce the pressurized effect of pressurized machine to the waste gas energy.
This shows, no matter be the exhaust-gas turbocharger of band bypass valve, or automatically controlled variable voluted type exhaust-gas turbocharger, its method of regulating pressurized effect all is the utilizations that reduce motor combustion gas energy, and the regulation range that is automatically controlled variable voluted type exhaust-gas turbocharger is bigger, degree of regulation is higher.
