之前我们曾经提到过,目前市而上流行的一些变缸技术,实际效果并没有想象中的那么好。与此同时,由于这些技术仍需要通过较为复杂的结构来实现.导致了其“性能成本比”不高、这也是全球范围内采门用变缸技术的厂商并不多的主要原因。最近,丰田的一个小动作引起了我们的关注。在它最新发布的RCF,以及即将上市的NX所配备的发动机上,都采用了一种循环的切换装置——可根据工况选择奥托俯环与阿特金森循环。或许很多人没有意识到,这项切换的功效,其实就等效于、甚至优于主流的变缸技术。
We have mentioned before, the current city of some of the popular cylinder technology, the actual effect is not as good as imagined. At the same time, due to the fact that these technologies still need to be implemented through more complex structures, this results in a low performance-cost ratio, which is also a major reason why there are not many manufacturers of variable-cylinder technology in the world. Recently, a small Toyota action caught our attention. In its latest release of the RCF, as well as the forthcoming NX equipped engines, have adopted a cycle of switching devices - according to the conditions to choose Otto top and Atkinson cycle. Perhaps many people do not realize that the effect of this switch, in fact, equivalent to, or even better than the mainstream variable-cylinder technology.
