Yes, this is the pic that I mentioned...
There is a control valve to passby the supercharge..Since there is a lot of coordination between electric clutch and control valve...Not sure if it will make the output power not stable...
I guess the working mechanism between the control valve and the electromagnetic clutch may not be as complicated as we had been thinking.........possibly it would just operate simultaneously with the cluth so as to provide a direct inlet of fresh air without going through the "fans" of the supercharger.
Actually the writer had provided a description on the working logic:
" 具体来说,TSI的涡轮是根据以下逻辑进行动作的:
1.在低转速时,由于废气涡轮的迟滞效应,大部分的增压压力都由机械增压器产生。发动机低转响应性更好,废气涡轮增压器的启动更加平顺。
2.当转速达到1500rpm时,两个增压器同时产生作用,总增压值达到2.5bar。随着转速提高,废气涡轮增压器使发动机获得更大的动力,而机械增压器由于摩擦的增大,增压效果逐渐降低。
3.当转速超过3500rpm时,发动机管理系统控制电磁离合器分离,使得机械增压器退出工作,减少摩擦损耗。此时,废气涡轮增压器完全提供发动机的增压压力。"
The control of the valve should be critical in the old design of Lancia, but for Volkswagen one I think the timing and rpm level setting of the electromagnetic clutch should play the most important role......
No matter how...I only interested if those changeover between supercharge/electric clutch/turbo/valve is smooth or not...
