起动发动机

电子控制模块(ECM)将会自动提供起动发动机所需的正确的油量。 盘车起动发动机时不应踩下油门。 如果发动机在 30 秒钟内无法起动,应释放起动马达开关。 再次使用之前,应使起动马达冷却两分钟。


注意

过量使用乙醚会造成活塞和活塞环损坏。 只在寒冷天气起动时才使用乙醚。


冷起动模式操作

当冷却液温度低于 18 °C (64 °F) 时,ECM 将会制定冷起动策略。

启动冷起动策略时,低怠速转速将会被提高到1000 rpm,发动机的功率将会被限制。

符合下述任一情况时,冷起动模式操作就会停用:

  • 冷却液温度达到 18 °C (64 °F)

  • 发动机已经运转了 14 分钟。

冷起动模式操作改变喷油量以清除白烟。 冷起动模式操作也通过改变正时以清除白烟。 通常在绕机检查结束之前就可以达到发动机工作温度。

冷起动模式结束之后,发动机应在低转速运转,直到发动机达到正常工作温度。 当发动机运行在额定转速和低功率需求时,达到正常工作温度的时间要快些。

客户指定参数

可以针对几个用户指定参数对发动机进行编程。 有关每一个客户指定参数的简述,请参阅操作和保养手册。
