After Starting Engine
起动后,发动机可保持在低转速高达 30 秒,以便使发动机系统稳定下来。 低速运转时间取决于环境温度,自上次运转的间隔时间及其它因素。
注: 在环境温度为
当发动机暖机怠速时,观察以下情况:
不要在发动机或起动马达运行时检查高压燃油管。 如果您检查正在运行的发动机,请始终使用正确的检查步骤以避免液体穿透危险。 请参考操作和保养手册, "一般危险信息"。
- 带负载运转发动机前,在怠速转速和半最高转速(发动机无负载)下检查是否有油液和空气泄漏。 该检查在部分应用中可能无法进行。
- 让发动机怠速运转 3 到 5 分钟,或让发动机怠速至水温指示开始升高。 在暖机期间,检查所有仪表。
恒速发动机应在低怠速运转 3 分钟之后,再以工作速度运转。 如果没有低怠速选项,则让发动机以工作速度无负载运转 2 分钟。
注: 发动机运行时,应观察仪表读数,经常记录数据。 比较长期数据将有助于确定每一个仪表的正常读数。 比较长期数据也将有助于发觉非正常运行的发展变化。 应调查读数中的明显变化。
