低油压的迹象
If you notice any of these symptoms, you will want to know how to check the oil pressure in a car before any further damage occurs.
警告灯打开
Your vehicle’s warning light is the first sign that something is wrong. This light connects to a sensor in charge of monitoring oil levels. When the pressure becomes too low, your light should alert you. When you see this indicator, don’t mess around. Have your vehicle serviced immediately.
燃烧的油味
每当您闻到石油燃烧的时间，您都会立即采取行动。这可能是机油泄漏在发动机组件上滴落的迹象。让发动机冷却，然后检查石油水平。如果它很低，则可以将其放在上面，但是您需要查看压力问题或泄漏。
Deep knocking or thumping sound
当您的车辆运行时，没有适当的油压，就会发生敲击声音。声音来自润滑不足的阀门和凸轮轴，最终导致更大的问题。不要只是扔best oil additive for engine knock, but resolve to find the condition causing the noise.
闲置时汽车问题
每当发动机未收到所需的石油量时，它都会导致性能问题。在大多数情况下，这些性能问题将在空转时揭示自己。在低速和空转时，请注意车辆的声音和感觉。
低发动机压力的常见原因
Low level of engine oil
您遇到低油压的第一原因是因为没有足够的油。定期检查和调整，除非系统泄漏，否则这不是问题。最好每月至少检查一次油水平。
引擎磨损
If your oil level is where it should be, the problem might be engine wear instead. Worn engine bearings in high-mileage motors often cause trouble with oil pressure because the flow is restricted. When this occurs, you most likely need an引擎重建or replacement.
损坏的油压量表
学习如何检查油压力表并不难。如果您的警告灯亮起，但是级别是正确的，则要检查有缺陷的发送单元。这也可能需要您更换油压传感器或油泵。很难弄清楚如何在没有规格的情况下检查油压，因此请不要犹豫将其签出。
肮脏的机油滤清器
Oil is a lubricant that must reach the engine. However, the机油滤清器阻碍。正常工作时，它允许使用适量的油。如果它被堵塞并且旁路阀无法正常工作，则您的发动机将无法收到所需的机油并开始遭受损失。
石油粘度
选择机油时，必须选择正确的粘度。机油粘度取决于您驾驶的车辆类型及其使用的电动机。当您选择粘度高于所需的粘度时，油可能会变得太厚，无法正确地通过系统移动。
Worn Out Oil Pump
车辆的油泵将油通过系统移动。如果油泵无法正常工作，则可能无法为发动机提供所需的润滑剂。有时，由于安装不良或维护故障，泵会失败，但绝对不能忽略它，否则您可能会遇到严重的发动机损坏。
引擎过热
As the engine overheats, the oil also gets hotter. This causes the oil to get thinner than intended. Just like thick oil can create problems, so can thinner viscosity oil. The lubricant might not properly work around the components and prevent engine damage from occurring.
How to Diagnose Low Oil Pressure
如果你想学习如何检查油压a car, all you need to do is look at the pressure gauge. If you receive a zero reading, there is something significantly wrong. Either no oil is being pumped into the system, or your gauge is faulty.
As you learn how to check low oil pressure and notice a low reading on the gauge, it could be a leak or worn out part. You shouldn’t run your engine any longer with low or non-existent pressure unless you want to deal with expensive engine repairs. However, you might also notice a consistently high oil pressure reading. This can also indicate trouble with your oil filter or a blockage in a delivery line.
Once you know how to check oil pressure manually and notice a problem, you want to take action. First, check the oil level to make sure it doesn’t require a top-off. You should also check the system for leaks. If you need professional help, a mechanic can run further tests.
对低油压进行故障排除
You want to know how to check the pressure and also how to check if an oil pressure sensor is bad. Follow these steps if you plan to do it on your own.
-
1启动您的车辆并将其放在地面上。
-
2观察油压力表。
-
3Check the engine oil level with the dipstick. Fill up if needed.
-
4卸下油压开关，并使用发动机的手动量规检查读数。您应该看到25至45磅。
-
5The oil pump screen could be contaminated. Drop the engine oil pan to clean the screen. You may also need to replace the oil pump.
Aside from these steps, you are looking at a major problem causing your low oil pressure, such as a faulty engine bearing or oil pressure relief valve.
人们也问（常见问题解答）
您可以用低油压驾驶汽车吗？
您绝对不要以低油压驾驶车辆，否则可能会造成严重的发动机损坏。取而代之的是，了解如何检查汽车上的油压并解决问题。
我可以在我的车上加新油吗？
当较低水平良好时，在汽车上添加一点油时，这并不是您所做的。切记进行定期换油以保持发动机的运转状态。
发动机可以用低油运行多长时间？
The effects of running a vehicle without the right amount of oil are disastrous to car engines. Without any oil, an engine would run for a few minutes before completely failing.
是什么导致柴油发动机以低油压运行？
无论您使用汽油还是柴油发动机都没关系。低油压的原因保持不变。检查系统中的油量，寻找泄漏并排除任何机械问题。
结论
是什么导致油压低？我们已经回顾了最高问题，并向您展示了如何解决问题。无论您做什么，都不要以低油压驾驶车辆，否则您可能会破坏发动机。
