遵循此程序中的所有步骤获得可用的机油压力读数。
- 确保发动机用 SAE 10W-30 机油加注至正确油位。 如果使用粘度不正确的机油,则发动机机油压力图表可能不准确。
- 拆卸机油压力开关。 将 1U-5470 发动机压力总成 连接至主机油歧管。 使用机油压力开关位置 (1) 处的接头。
- 运转发动机。 使发动机机油温度升至 99°C (210°F)。
注: 发动机机油温度每升高 3°C (5°F),将使发动机机油压力降低 7 kPa (1 psi)。
注: 确保发动机机油温度不升至 115°C (239°F) 以上。
- 使发动机机油温度在发动机额定转速下保持不变,然后读取压力表。
- 根据发动机转速和机油压力,找到发动机机油压力图表中的交叉点。
- 结果应在图表可接受的范围内。 如果结果不可接受,找到问题原因并修正问题。 发动机故障和发动机使用寿命缩短,可能是在机油压力超出可接受范围时持续运行造成的。
注: 保持规定间隔的发动机机油压力记录。 该记录可指示可能的发动机故障或损坏。 机油压力突然升高或突然降低 70 kPa (10 psi) 时,应进行检查,即使处于发动机机油压力图表的可接受范围。
