Air Inlet and Exhaust System - Inspect
应对进排气系统进行综合性目视检查。 确保系统中没有泄漏迹象。
如果进气系统或排气系统中存在阻塞，则发动机的性能就会降低。
- 检查发动机空气滤清器进气口和进气管道以确保通道没有被阻塞或压扁。
- 检查发动机空气滤清器滤芯。 用清洁的发动机空气滤清器滤芯更换脏的发动机空气滤清器滤芯。
- 检查发动机空气滤清器滤芯清洁的一侧有无灰尘的踪迹 。 如果观察到灰尘的踪迹，说明污染物正流过发动机空气滤清器滤芯和/或发动机空气滤清器滤芯密封件。
- 对于配备塑料气门机构盖的发动机，如果曲轴箱压力过大，则拆下气门机构盖。 请参考拆解和组装, "气门机构盖 - 拆卸和安装"以了解正确步骤。 检查气门机构盖的内部有无碎屑。 确保清除了所有碎屑。
