漏轮增压的好与坏,这个问题的争议性早已不似当年。不过在具体的技术应用上,还是存在着一个矛盾点——性能与迟滞。从结构上这很好理解:想缓解迟滞得用小涡轮,但这显然不利于提升功率。如何更好地平衡这二者,正是目前各路厂商工程师主攻的课题。方法已经有很多了,例如早期的可变翼涡轮、双涡轮、机械+涡轮、单涡轮双涡管等等,不一而足。就在最近,奥迪又整出个新花样——三增压(首台机型为SQ7上
Turbocharged good and bad, the controversy of this issue has long been similar to the year. However, in the specific application of technology, there is still a contradiction - performance and delay. This is well understood from a structural point of view: to ease the hysteresis of a small turbine, it is obviously not conducive to increasing power. How to better balance these two is the subject of the current engineers of various manufacturers. There are already many ways, such as early variable-wing turbines, twin turbines, mechanical + turbines, single-turbine twin-scroll and so on. Just recently, Audi put out a new pattern - three supercharged (the first model for the SQ7
