摘要
将已定型的50mL两轮摩托车最快、最经济地改进成两轮轻便型摩托车的方法有:改变传动比、限制节气门开度和改变点火器的点火提前角。通过分析,这三种方法中,只有改变点火提前角,使发动机外特性曲线左移才能达到降低最高车速、保证后备功率的目的。这种方法较另两种方法简单易实现。
The faster and more economic ways of changing the 50mL two-wheeled motorcycle into a two-wheeled moped are (1) change the gear ratio, (2) limit the throttle opening. (3) adjust the ignition advance angle,which is considered the best way a-mong the three for by moving the external characteristic of the engine left,lowing the max speed and keeping the reserve horsepower could be realized.
