In the lobed impeller the measuring chambers are the space between the lobes and the meter housing. 叶轮式测量室是叶轮和流量叶壳体间的空间。
The trigger wheel rotates with engine RPMs and causes the speed sensor, or pickup oil, to produce triggering voltage pulses that correspond to engine speed and piston position. 触发叶轮随发动机转速而旋转，使得转速传感器或拾波线圈产生与发动机转速和活塞位置相对应的触发电压脉冲。
The sky overhead is an eight-spoked prayer wheel and the ground below an eight-petalled lotus. 天如八幅轮，地如八瓣莲，吉祥无比。
