其优点如下：Advantages:
1、摩托车怠速3秒自动熄火，有效减少怠速油耗，降低 怠速排放。As the idle time is 3s, the motorcycle will be power off so as to reduce the idle fuel consumption and emission. 2、怠速熄火后，拉油0.5S内完成启动，响应时间短。After idling stop, The starting is finished within 0.5s, the response time is short. 3、磁电机直接拖动，无减速齿轮，启动噪音更小。There is no reduction gear, the starting is by magneto

什么是ACG智能启动技术？What is the ACG intelligent start technology?
ACG智能启动技术是用三相无刷永磁电机取代传统的启动电机（有刷直流电机），在启动时，通过 控制器驱动ACG转动，并拖动发动机运动，已达到发动机启动的目的。 The 3-phases brushless permanent magneto motor replaces the traditional starting motor(brush DC motor), when the engine is starting, the control module drive the ACG to rotate so as to drive the engine move.

什么是怠速停止系统（I-STOP）？What is the idling stop system (I-STOP)?
怠速停止系统是当驾驶者遇到红灯或者道路拥堵而进行制动操作时，发动机自动熄火，再次起步时 自动点火的控制系统。 The idling stop system is a control system that the engine is flameout automatically when the driver does the brake action meet the traffic light or the traffic jam, when starting again, the engine is auto ignited.
3、根据曲轴位置信号输出点火 Based on the
crankshaft’s location, do ignition.
4、检测外部条件完成怠速熄火及拉油启动功能。
Detect the external condition, achieve the
idling stop and starting function.
其优点如下 Advantages：
1、启动电流更小。The starting current is low. 2、取消启动电机、启动继电器、减速齿轮，将整流器、CDI集成到驱动器。 Cancel the starting motor, start relay, reduction gear, integrate the rectifier and CDI into the actuator. 3、使整车结构更简单。The motorcycle’s structure is more simple.
