如果空气进入燃油系统,在起动发动机之前,必须排出空气。 发生以下事件时,空气可能会进入燃油系统:
- 正常工作期间排空燃油箱或部分排放燃油箱。
- 断开低压燃油管。
- 发动机运转过程中低压燃油系统发生泄漏。
- 更换燃油滤清器或燃油泵。
- 断开高压燃油管。
按照以下步骤,排出燃油系统中的空气:
- 拆下燃油喷嘴的盖。
- 将钥匙开关转到运转位置保持三分钟,使注油泵通电。 不要起动发动机。 然后将钥匙开关转到断开位置。
- 松开高压燃油管 (1) 的接头。

- 操作电动起动马达直至接头处流出无空气的燃油。
- 拧紧高压燃油管的接头至扭矩为 30 N·m (22 lb ft)。
- 起动发动机并检查有无泄漏。
- 安装燃油喷嘴的盖。
