Since the distance between these two points is 182 units, the fundamental frequency is fs/(182/5)= 16000/(182/5)= 439.56 Hz, which is equal to 68.9827 semitones.

在上述范例中，上图红线的位置代表音框的位置，下图即是 256 点的音框，其中红线部分包含了 5 个基本周期，总共占掉了 182 单位点，因此对应的基本频率是 fs/(182/5)= 16000/(182/5)= 439.56 Hz，相当於 68.9827 半音，其中由基本频率至半音的转换公式如下

When the swirl variable device is part-opened, because swirl has some effect on the second injection, second injection timing has distinctly effect on fuel consumption, and the fuel consumption change fluctuantly with twice injection timing. When the tumble variable device is adopted, second injection timing also has effect on fuel consumption, but there is only one point that the fuel consumption is lowest. When the load is bigger, the second injection point where the fuel consumption is lowest is earlier than the smaller load.

在可变涡流结构中，当阀片处于非全开状态时，由于涡流运动对二次喷油的作用，二次喷油正时对发动机的比油耗存在明显影响，发动机比油耗随喷油正时改变呈较明显的波动状；在可变滚流结构中，二次喷油正时对发动机比油耗同样存在影响，但最低油耗点只有一个，当负荷较大时，最低比油耗所对应的喷油正时要更早一些。
