| 事件代码 | ||
|---|---|---|
| 说明 | 产生此代码的情况 | 系统响应 |
| E092 增压压力高于正常值 | 实际增压压力高于所需增压压力。 | 记录此代码，且此代码处于当前状态。 |
可能的原因
- 废气门膜片泄漏
- 供气
- 满负荷油量设置 (FLS) 有误
建议措施
废气门膜片泄漏
确认废气门的排气旁通阀能够打开。 使用卡特彼勒电子技师（ET）将废气门设为完全打开。 进行变矩器失速测试。 30 秒后，应该会出现增压过低事件。 如果发生增压过低事件，则说明废气门可正常开启。
供气
确认废气门控制阀的供气不低于 345 千帕 (50 磅/平方英尺)。
FLS 有误
确保 FLS 正确。
